Abstract
PURPOSE OF REVIEW Hip arthroscopy is widely used for the management of intra-articular pathology and there has been growing interest in strategies for management of the hip capsule during surgery. The hip capsule is an essential structure that provides stability to the joint and it is necessarily violated during procedures that address intra-articular pathology. This article reviews different approaches to capsular management during hip arthroscopy including anatomical considerations for capsulotomy, techniques, clinical outcomes, and the role of routine capsular repair. This article also reviews the concept of hip microinstability and its potential impact on capsular management options as well as iatrogenic complications that can occur as a result of poor capsular management. RECENT FINDINGS Current research highlights the key functional role of the hip capsule and the importance of preserving its anatomy during surgery. Capsulotomies that involve less tissue violation (periportal and puncture-type approaches) do not appear to require routine capsular repair to achieve good outcomes. Many studies have investigated the role of capsular repair following more extensive capsulotomy types (interportal and T-type), with most authors reporting superior outcomes with routine capsular repair. Strategies for capsular management during hip arthroscopy range from conservative capsulotomy techniques aimed to minimize capsular violation to more extensive capsulotomies with routine capsule closure, all of which have good short- to mid-term outcomes. There is a growing trend towards decreasing iatrogenic capsular tissue injury when possible and fully repairing the capsule when larger capsulotomies are utilized. Future research may reveal that patients with microinstability may require a more specific approach to capsular management.

Abstract
PURPOSE Larger-than-planned capsulotomies can occur, yet their association with age and eye parameters remains poorly understood. This study aimed to assess capsulotomy enlargement after femtosecond laser treatment in cataract surgery and to explore a possible correlation of capsulotomy enlargement with age and eye parameters. METHODS This retrospective case series included consecutive patients diagnosed with cataracts between 05/2018 and 11/2019. Among them, patients within the age ranges of <18, 18-49, and ≥50 years were assigned to the childhood cataract (CC), young adult cataract (YAC), and age-related cataract (ARC) groups, respectively. The capsulotomy enlargement ratio (CER), age, degree of cataract, lens thickness (LT), axial length, and anterior chamber depth were recorded and analyzed. RESULTS A total of 155 participants (179 eyes) were enrolled. The CER was significantly different among the three groups (CC: 1.245 vs. YAC: 1.060 vs. ARC: 1.029, P<0.001). The CER was found to be independently associated with both age (β=-0.011 (0.001), P<0.001) and LT (β=-0.049 (0.017), P=0.006) in the CC group, but it was only independently correlated with age (β=-0.004 (0.001), P=0.002) in the YAC group and LT (β=-0.014 (0.007), P=0.048) in the ARC group. CONCLUSIONS Capsulotomy enlargement can occur after femtosecond laser treatment in cataract surgery, especially in the non-adult group. Age was a determinant of the CER in CC and YAC groups, while LT was an independent determinant of the CER in CC and ARC groups. These two factors should be taken into consideration for more precise sized capsulotomy.

Abstract
BACKGROUND Decision making is frequently associated with risk taking under uncertainty. Elevated intolerance of uncertainty is suggested to be a critical feature of obsessive-compulsive disorder (OCD). However, impairments of latent constructs of uncertainty processing and its neural correlates remain unclear in OCD. METHODS In 83 participants (24 OCD patients treated with capsulotomy, 28 OCD control participants, and 31 healthy control participants), we performed magnetic resonance imaging using a card gambling task in which participants made decisions whether to bet or not that the next card would be larger than the current one. A hierarchical drift diffusion model was used to dissociate speed and amount of evidence accumulated before a decisional threshold (i.e., betting or no betting) was reached. RESULTS High uncertainty was characterized by a smaller amount of evidence accumulation (lower thresholds), thus dissociating uncertainty from conflict tasks and highlighting the specificity of this task to test value-based uncertainty. OCD patients exhibited greater caution with poor performance and greater evidence accumulation overall along with slower speed of accumulation, particularly under low uncertainty. Bilateral dorsal anterior cingulate and anterior insula distinguished high- and low-uncertainty decision processes in healthy control participants but not in the OCD groups, indicating impairments in anticipation of differences in outcome variance and salience network activity. There were no behavioral or imaging differences relating to capsulotomy despite improvements in OCD symptoms. CONCLUSIONS Our findings highlight greater impairments particularly in more certain trials in the OCD groups along with impaired neural differentiation of high and low uncertainty and suggest uncertainty processing as a trait cognitive endophenotype rather than a state-specific factor.

Abstract
PURPOSE The purpose of the study was the clinical evaluation of the capsular management with arthroscopic treatment of femoroacetabular impingement and labral tears by comparing the functional outcomes of closed versus open capsule. METHODS Patients with a median age of 38 years (18-55), clinical and radiological features of FAI and/or labral tear, and non-arthritic non-dysplastic hips were selected for arthroscopic treatment. Capsulotomy was performed primarily as an interportal section, then a distal extension preserving the zona orbicularis was added. The study compared two matched groups: patients with open capsule versus patients with closed capsule. Clinical outcomes were assessed by Non-Arthritic Hip Score, hip outcome scores of daily living activities and sports-specific scales. Scores were collected preoperatively and 6 months, 2 years and 5 years postoperatively. Rate of revision arthroscopy and conversion to total hip arthroplasty were used for comparing groups. Minimal clinically important differences were calculated for both groups. RESULTS The study included 42 patients in the OC group and 44 patients in the CC group. Significant improvement of postoperative PROMs was recorded in both groups compared to preoperative scores. CC group significantly improved more than the OC group based on NAHS, HOS-ADL and HOS-SSS over all check points except for NAHS and HOS-ADL at 6 months, which were statistically non-significant. A non-significant difference was observed in the percentage of patients who met the MCID for all reported outcome scores at 5 years in both groups. The rate of reoperation was similar in both groups, but with different indications. CONCLUSION Arthroscopic treatment of FAI and labral repair with complete closure of the hip capsule led to significantly improved functional outcomes after 5 years follow-up compared with open capsule. Closed capsule can provide greater improvement in the sports-specific outcomes at early follow-up. Controlled capsulotomy limited by zona orbicularis did not produce instability at any postoperative stage. Similar proportions of patients achieved minimal clinically important difference, and similar rates of reoperation were reported in both groups. LEVEL OF EVIDENCE III.

Abstract
Neurosurgery is a therapeutic option for patients with refractory obsessive-compulsive disorder who do not respond to previous treatments. Although its efficacy in reducing clinical symptomatology has been proven, few studies have analyzed its effects at the cognitive level. The aim of this systematic review was to describe the cognitive outcomes of functional neurosurgery in patients that went through capsulotomies or cingulotomies. PubMed, Medline, Scopus, PsycInfo, PsyArticles, and Web of Knowledge were searched for studies reporting cognitive outcomes in refractory obsessive-compulsive patients after capsulotomies and cingulotomies. The risk of bias was assessed with the Assessment Tool for Before-After (Pre-Post) Studies With No Control Group tool; 13 studies met inclusion criteria, including 205 refractory obsessive-compulsive disorder patients for both surgical procedures. Results showed a substantial number of studies that did report significant cognitive improvement after surgery, being this improvement specially related to memory and executive functions. The second-most frequent finding is the maintenance of cognitive performance (nor improvement or worsening). From a neuropsychological point of view, this outcome might be considered a success, given that it is accompanied by amelioration of obsessive-compulsive symptoms. Subtle cognitive adverse effects have also been reported. Neurosurgery procedures appear to be safe from a cognitive point of view. Methodological issues must be improved to draw clearer conclusions, but capsulotomies and cingulotomies constitute an effective alternative treatment for refractory obsessive-compulsive disorder patients.

Abstract
In neurosurgery, spatial normalization emerged as a tool to minimize inter-subject variability and study target point locations based on standard coordinates. The Montreal Neurological Institute's 152 brain template (MNI152) has become the most widely utilized in neuroimaging studies, but has been noted to introduce partial volume effects, distortions, and increase structure size in all directions (x/y/z axes). These discrepancies question the accuracy of the MNI template, as well as its utility for studies that examine and form conclusions from group-level data. Given that surgical precision in obsessive-compulsive disorder is essential to patient outcomes, we retrospectively investigated lesion size and location in patients (n = 21) who underwent capsulotomy for intractable OCD, comparing deviations in the native scans to those in standard space. MNI measurements were significantly larger than native measurements across several structures in both coronal and axial slices, and we found that MNI transformation increases the size of many subcortical structures in a significant and proportional way for both females and males. These findings urge caution when using MNI as a reference space, as well as a stronger consideration of population-specific brain templates when examining connectivity-based networks.

Abstract
Purpose The Argentinian flag sign, or radial capsular tear extensions, is a rare complication when performing capsulorhexis during cataract surgery. Identifying and managing this complication early is important to prevent the tear from propagating around the periphery leading to posterior capsular rupture or vitreous loss. Observations The Argentinian flag sign was previously reported in a case of femtosecond laser-assisted cataract surgery (FLACS). However, our report presents the first case after FLACS using the Catalys™ Precision Laser System, a platform which has been associated with a larger percentage of complete capsulotomies when compared to other platforms. Radial extensions of the capsular tear were observed in a 27-year-old male patient with an intumescent cataract in left eye. The complication was managed by manually redirecting and completing the radial extension flaps, along with delicate phacoemulsification and manual cutting of capsular edge in areas with significant capsular-IOL overlap. Conclusions and importance Our case report highlights that despite the Catalys™ Precision Laser System success rates, radial tears may occur, especially in highly pressurized intumescent cataract. Therefore, surgeons must be prepared to optimize the surgical techniques to prevent the occurrence of this complication, as well as identify and manage it when it presents.

Abstract
Capsulorhexis in white intumescent cataract is often associated with extension leading to radial tears or biradial extension "Argentinian flag sign" and associated complications. We describe a novel technique of managing this situation. Vacuum rhexis is performed with a 24 G bent cannula attached to a 10-ml syringe. The flap is lifted and then caught using 24 G cannula. The suction is manually controlled by the surgeon, and the rhexis is completed using circumferential movement. The chamber stability is well maintained as there is no leakage, and the bent tip gives excellent fulcrum for movement. The advantage of this technique is that a single port is used for maintaining the chamber stability and it needs no special surgical instruments. Vacuum rhexis is a novel surgical technique used for performing successful continuous curvilinear capsulorhexis (CCC) of adequate size in white and intumescent cataracts, with a consistent and predictable outcome.

Abstract
BACKGROUND AND OBJECTIVES Ablative lesion procedures remain as the last option in treatment of refractory depression. Contemporary ablative psychosurgeries involve producing lesions in the anterior limb of the internal capsule (bilateral anterior capsulotomy - BAC), the supragenual anterior cingulate gyrus and cingulum (bilateral anterior cingulotomy - BACING), and subgenual anterior cingulate gyrus and subcortical orbitofrontal white matter (bilateral subcaudate tractotomy - BST). A combination of BACING and BST is known as limbic leukotomy (bilateral limbic leukotomy - BLL). All procedures claim some success, but cohorts are small, depression assessment instruments differ, and inclusion and outcome criteria and follow-up duration vary. In some cohorts, more than one type of surgery was performed in several patients, further confounding interpreting the available data. Current evidence is equivocal on which surgical target works best. Method and Aim: This systematic review and meta-analysis using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) standard on published cohorts was conducted to review and identify which is the best standalone ablative procedure for treatment-resistant depression (TRD) based on response rate (event rate) and adverse-effect profile using the Comprehensive Meta-Analysis software. RESULTS AND CONCLUSION As a standalone neurosurgical procedure, we found that BAC appears to be the most effective and safest of all the ablative targets for TRD. A major limitation of this conclusion is the paucity of published case series where sample sizes are small and all are open label.

Abstract
Autism spectrum disorder (ASD) is a developmental disability of the brain that can be associated to severe conductual alterations, such as self or heteroaggression and obsessive and compulsive behavior. Many of these patients do not improve with any pharmacological or behavioral therapy and represent a major social problem. We describe the outcome of patients with ASD, treated with radiofrequency brain lesions combined with Gamma Knife radiosurgery for therapy-resistant aggressiveness, obsessive thoughts, and compulsions. The ASD adapted YBOCS, PCQ and EAE scales assessed the therapeutic effect on symptoms. All patients had a significant reduction of their symptoms (YBOCS:34 and 22 PCQ 42 and 35, EAE 11 and 5.5, respectively), although all needed more than one treatment to maintain this improvement. The treatments resulted very safe for the patients and their neurological status has not change. We conclude that in these patients after surgery, there is a marked improvement in behavior, quality of life and relationship with the environment, with no evidence of secondary damage. Changes in connectivity might mediate the clinical improvement, although it is necessary to confirm these results with further studies.

Abstract
PURPOSE To assess the recovery of extension and improvement in functional scores after an arthroscopic or open posterior knee capsulotomy in the setting of an extension deficit. METHODS A systematic search of articles published between 1980 and 2020 was performed in the MEDLINE/PubMed database, EMBASE/Ovid database and Web of Science database. The inclusion criteria consisted of patients with primary extension deficits > 5° who underwent an arthroscopic or open posterior knee capsulotomy. The assessed outcomes were preoperative and postoperative range of motion and functional outcome scores. Randomized controlled trials, cohort studies and case series with a follow-up longer than 6 months were included. The risk of bias was assessed using the Joanna Briggs Institute critical appraisal tool for case series. The certainty of evidence was assessed using the GRADE approach. RESULTS Of 226 records identified through database searching, 7 studies were included in the final analysis. The outcomes of 107 patients with a mean age of 34.1 (range 15-63) years were available. In all the included studies, a posterior capsulotomy resulted in the restoration of knee extension to normal or nearly normal values (mean postoperative extension deficit: 0.4-4.2 degrees) with a significant increase in functional outcome scores. No neurovascular complications were reported within the studies. Due to the diverse methodology of studies, the direct comparison of arthroscopic versus open approaches was not possible. Concerning the risk of bias assessment, the greatest concerns raised the selection of participants among the included studies and the methods of outcome measurement. The certainty of evidence was very low according to the GRADE. CONCLUSIONS Both arthroscopic and open posterior capsulotomy of the knee results in restoration of normal or nearly normal knee extension and significant improvement in functional outcomes. LEVEL OF EVIDENCE IV.

Abstract
Making lesions in the brain to relieve the distress of mental illness has had a checkered career due to a mixture of misuse and also caution about making permanent lesions in the brain where there was no physical abnormality. However, over the last 10 years a more flexible approach has developed. The method is still in its infancy and very little used. However, GKNS has been shown to be useful for OCD and also some cases of sever anxiety. It has been attempted for depression and anorexia nervosa but at present its role for these conditions remains to be determined.

Abstract
BACKGROUND Psychiatric surgery is an important domain of functional neurosurgery and involves deep brain stimulation (DBS) or lesional procedures performed for treatment-resistant psychiatric illness. It has recently become possible to use magnetic-guided focused ultrasound (MRgFUS) to perform bilateral capsulotomy, a lesional technique commonly carried out with surgical radiofrequency ablation or stereotactic radiosurgery. MRgFUS offers several advantages, including improved safety and real-time imaging of the lesions. OBJECTIVE To describe the clinical and technical aspects of performing bilateral MRgFUS capsulotomy in patients with severe refractory depression and obsessive-compulsive disorder. METHODS We describe the clinical and technical considerations of performing MRgFUS capsulotomy. Topics discussed include patient selection, headframe application, targeting, sonication strategies, and follow-up procedures. RESULTS MRgFUS capsulotomy was performed in 16 patients without serious clinical or radiographic adverse events. CONCLUSION MRgFUS allows for a safe, less invasive technique for performing a well-studied psychiatric surgery procedure-the anterior capsulotomy.

Abstract
INTRODUCTION A subgroup of patients with autism spectrum disorder (ASD) show self or heteroaggression, dyscontrol episodes, and others are of obsessive-compulsive disorder (OCD) profile; some of them are resistant to medical and behavioural treatment. We describe the long-term outcome in a group of these patients, treated with radiofrequency brain lesions or combined stereotactic surgery and Gamma Knife (GK) radiosurgery. METHODS We reviewed the medical records of 10 ASD patients with pathological aggressiveness and OCD, who had undergone radiofrequency lesions and/or radiosurgery with GK in our institution. RESULTS The 10 patients had a significant reduction of their symptoms (PCQ 39.9 and 33, OAS 11.8 and 5, CYBOCS-ASD 30.4 and 20), preoperatively and in the last follow-up, respectively; p < 0.005 (in all cases), although all but 2 needed more than 1 treatment to maintain this improvement. CONCLUSIONS We observed a marked improvement in behaviour, quality of life, and relationship with the environment in all our 10 patients after the lesioning treatments, without long-lasting side effects.

Abstract
BACKGROUND Bilateral anterior capsulotomy (BAC) is an effective surgical option for patients with treatment-resistant major depression (TRMD) and treatment-resistant obsessive-compulsive disorder (TROCD). The size of the lesion and its precise dorsal-ventral location within the anterior limb of the internal capsule (ALIC) remain undefined. OBJECTIVE To present a method to identify the trajectories of the associative and limbic white matter pathways within the ALIC for targeting in BAC surgery. METHODS Using high-definition tractography, we prospectively tested the feasibility of this method in 2 patients with TRMD and TROCD to tailor the capsulotomy lesion to their limbic pathway. RESULTS The trajectories of the associative and limbic pathways were identified in the ALIC of both patients and we targeted the limbic pathways by defining the dorsal limit of the lesion in a way to minimize the damage to the associative pathways. The final lesions were smaller than those that have been previously published. This individualized procedure was associated with long-term benefit in both patients. CONCLUSION Tractography-guided capsulotomy is feasible and was associated with long-term benefit in patients with TRMD and TROCD.

Abstract
BACKGROUND Obsessive-compulsive disorder (OCD) is a disabling condition characterized by intrusive thoughts and repetitive behaviors. A subset of individuals have severe, treatment-resistant illness and are nonresponsive to medication or behavioral therapies. Without response to conventional therapeutic options, surgical intervention becomes an appropriate consideration. OBJECTIVE To report clinical outcomes and the safety profile of bilateral ventral anterior capsulotomy for OCD using magnetic resonance (MR)-guided laser interstitial thermal therapy (LITT) in 10 patients followed for 6 to 24 mo. METHODS A total of 10 patients underwent LITT for severe OCD; 1 patient withdrew prior to follow-up. LITT is a minimally invasive ablative technique performed with precise targeting and use of thermography under MR guidance. Lesions of the ventral anterior limb of the internal capsule by other techniques have been shown to be efficacious in prior studies. RESULTS A total of 7 of the 9 patients were considered full responders (77.8%; Yale-Brown Obsessive-Compulsive Scale change ≥35%). Adverse effects included transient apathy/amotivation postsurgery (2 patients). One patient had a small tract hemorrhage where the laser fiber traversed the cerebral cortex as well as persistent insomnia postsurgery. One individual died after a drug overdose 7 mo postsurgery, which was judged unrelated to the surgery. CONCLUSION LITT ventral capsulotomy was generally well tolerated, with promising evidence of effectiveness in the largest such series to date. Results were comparable to those after gamma knife ventral capsulotomy, as well as ventral anterior limb deep brain stimulation.

Abstract
Creating pleasing breast aesthetics after an explantation can be challenging, especially when performed with a total capsulectomy. The necessity of a capsulectomy for a variety of breast issues is not completely agreed on and can increase adverse events, patient morbidity, and cost of the operation and often impairs the final aesthetic result. In this article, an algorithm for the management of explantation patients provides a framework for treatment of the capsule and the breast to optimize outcomes.

Abstract
BACKGROUND AND OBJECTIVE During capsulotomy, the force applied to the anterior capsule is a crucial parameter controlling capsule tears, that affects the clinical performance. This study aims to investigate the tear force in capsulotomy and analyze the effects of different tearing conditions on the tear force. METHODS A three-dimensional model of the human lens was constructed based on published clinical data using the finite element (FE) method. The lens model consisted of four layers: the anterior and posterior lens capsule, the cortex, and the nucleus. Distortion energy failure criterion combined with the bilinear interface law was used to express the crack propagation process at the edge of the anterior lens capsule. At the clamping position, a local coordinate system was established to parameterize the capsule tearing. The simulation results were then validated by conducting a capsulorhexis experiment using isolated porcine eyes with force-sensing forceps. RESULTS The simulation results showed a good agreement with the experimental data of two porcine specimens (No. 6 and 9) during a stable tearing process (p-values = 0.76 and 0.10). The mean force differences between the experimental data and the simulation were 3.10 ± 2.24 mN and 2.14 ± 1.73 mN, respectively. The tear direction with a minimum mean tear force was at θ1 = 0° and θ2 = 30°. The tear velocity was not significantly different to the variation in the tear force. However, an appropriate capsulorhexis diameter was found to contribute to the reduction of tear force. CONCLUSIONS The outcome of this paper demonstrates that our FE model could be used in modeling lens capsule tearing and the theoretical study of tear mechanism.

Abstract
We describe a case of radial extension and its management during femtosecond laser-assisted cataract surgery (FLACS) in a patient with intumescent cataracts. Radial extension was observed after injection of trypan blue into the anterior chamber. Management of the extension was achieved by separation of adhesions between the incomplete capsulotomy, along with manual completion at the areas of extensions. Careful observation during FLACS capsulotomy is advised in cases of intumescent cataracts due to the release of cortex into the anterior chamber which may interfere with the delivery of the laser treatment resulting in incomplete capsulotomy patterns. Furthermore, trypan blue staining is essential to identify possible incomplete capsulotomy patterns and extensions. The Argentinian flag sign may occur after femtosecond laser-assisted capsulotomy in cases of intumescent cataracts. Proper identification of incomplete capsulotomy patterns and radial extensions should be managed with careful manual completion of the capsulotomy.

Abstract
Background A prospective cohort study was performed to evaluate whether the Optical Quality Analysis System (OQAS) can serve as a valuable additional indicator for appropriate posterior capsulotomy referral. Methods One hundred and five eyes from 96 patients undergoing capsulotomy were divided into precapsulotomy logMAR CDVA ≤0.1 group and logMAR CDVA > 0.1 group. CDVA, and the Visual Function 14 index (VF-14) score were estimated before and 1 month after capsulotomy. The objective scattering index (OSI) value was measured by using the OQAS. Posterior capsule opacification (PCO) severity was assessed with Evaluation of PCO 2000 (EPCO 2000) software. Results In logMAR CDVA > 0.1 group, the correlations of OSI, logMAR CDVA, EPCO score and VF-14 score were very strong preoperatively. In logMAR CDVA ≤0.1 group, preoperatively, OSI was correlated with logMAR CDVA (r = 0.451), EPCO score (r = 0.789), and VF-14 score (r = 0.852). LogMAR CDVA has weak correlation with VF-14 score (r = − 0.384) and EPCO score (r = 0.566). VF-14 score was correlated with EPCO score (r = − 0.669). In the logMAR CDVA ≤0.1 group, there was no significant difference in logMAR CDVA between precapsulotomy and postcapsulotomy (P > 0.05). In the two groups, all the other optical quality parameters were significantly improved after capsulotomy (P < 0.05). In logMAR CDVA > 0.1 group, the area under the curve of the ROC of the OSI was 0.996 (P = 0.000). In logMAR CDVA ≤0.1 group, the area under the curve of the ROC of the OSI was 0.943 (P = 0.000). Conclusions The OSI was useful for evaluating of PCO and prediction of beneficial capsulotomy. Especially for patients with slight PCO and better visual acuity, OSI is more valuable than CDVA and completely objective examination. Trial registration The study protocol was registered at the Chinese Clinical Trial Registry. Register: ChiCTR1800018842 (Registered Date: October 13th, 2018).

Abstract
Using a cadaver study, we described a new dorsal approach to the wrist joint using a "U-shaped with proximal base" capsulotomy. Six fresh adult cadaveric wrists were dissected after intra-arterial silicone injection. We did a dorsal approach to expose the dorsal joint capsule. It was then possible to identify the dorsal radiocarpal and intercarpal ligaments, the dorsal radiocarpal and intercarpal arterial arches, the dorsal branch of the anterior interosseous artery and the terminal branch of the posterior interosseous nerve. Wrist arthrotomy was done using our capsulotomy. In each dissected capsular flap, we always found the individual ligament, vascular, and nerve structures, implying they were intact over their trajectories. The mean surface area of the articular exposure was 945 mm2 (range 725-1102 mm2) allowing easy access to the carpal bones and the radiocarpal and midcarpal joint spaces. This surgical approach to the wrist is technically feasible and avoids damaging the dorsal extrinsic ligaments fibers. Keeping the vascularization intact could improve capsular healing, while preserving innervation could maintain wrist proprioception.

Abstract
BACKGROUND The perfection and high reproducibility of capsulotomy in femtosecond laser-assisted cataract surgery (FLACS) lead to the possibility of new intraocular lens (IOL) designs for capsulotomy fixed implantation. ISSUE Which different designs have so far been presented for which problems in capsulotomy fixation? MATERIAL AND METHOD An evaluation of the literature and conference data was carried out. RESULTS Currently four different types of femtolenses for capsulotomy fixation are described in the literature or are commercially available. The first described was the lens in the bag or Tassignon IOL, which was developed for secondary cataract prevention, the second was the Masket IOL for reduction of negative dysphotopsia and third the 90F designed by Dick. All three types are or will be produced by Morcher. The fourth lens is the Femtis from Oculentis. All lenses are characterized by a high level of safety during implantation, The Tassignon lens leads to reduction of secondary cataract, especially in juvenile cataract because of the additional posterior capsulotomy. In studies the Masket IOL could show a decrease of negative dysphotopsia. In comparison to standard lenses, the 90F and Femtis in particular showed better results with respect to tilt, rotation and decentration. CONCLUSION The new IOL designs for capsulotomy fixation show a safe implantation procedure and indications for a very stable position in the capsular sac. Further studies must be carried out to confirm the possible advantages in comparison to standard IOL with respect to postoperative results for refraction, tilt, rotation and decentration and possible induction of aberrations.

Abstract
BACKGROUND Modern laser surgery uses Nd:YAG laser capsulotomy for posterior capsule opacification (PCO) and Nd:YAG laser vitreolysis for symptomatic vitreous floaters (VF). We report a case of acute retinal detachment seven days after Nd:YAG laser capsulotomy combined with Nd:YAG laser vitreolysis and analyze the cause of this complication. CASE PRESENTATION A 58-year-old myopic woman complained of decreased visual acuity and symptomatic floaters with her left eye for 3 months. We found she had significant PCO and VF in the posterior vitreous. She underwent neodymium-doped yttrium aluminum (Nd:YAG) laser vitreolysis immediately after Nd:YAG capsulotomy. After 7 days, she complained of rapid vision decline and dark shadows in her treated eye. We found she had a acute severe rhegmentogenous retinal detachment (RD) involving the macula. Then she underwent vitrectomy, retinal reattchment and silicone oil tamponade surgery immediately. Six months later, silicone oil was removed and the best corrected visual acuity (BCVA) of her left eye gradually improved to 10/20 and maintained during a 1-year follow-up period. CONCLUSION As myopic patients are at risk of developing retinal detachment, Nd:YAG vitreolysis and capsulotomy should be performed with caution. The laser energy should be as low as possible and careful focus is necessary to reduce interference to the retina.

Abstract
Background We investigated the incidence and location of heterotopic ossification (HO) following hip arthroscopy. Methods This retrospective study enrolled 327 patients who underwent hip arthroscopy from January 2010 to December 2015. From this cohort, we extracted an HO group with simple radiographs or three-dimensional computed tomography (3D CT). Findings consistent with HO were classified according to the Brooker classification aided with 3D CT for the location of HO. The indication for revision arthroscopic excision of HO was painful, functional impairment of the hip. Patient clinical outcomes were assessed pre- and postoperatively, with modified Harris Hip Scores (mHHS), a visual analogue scale (VAS) for pain, and the Hip Outcome Score-Activity of Daily Living (HOS-ADL) and Sport Specific Subscales (HOS-SSS). Results In all, 14 (4.28%) of the 327 patients had confirmed HO radiographically. The mean follow-up was 39 months. In 13 patients, HO formed in the central area of the arthroscopic portals or capsulotomy. Ten patients had Brooker Grade 1 and four had Grade 2. At the last follow-up, 12 asymptomatic patients had significant (P < 0.001) improvements in all clinical outcome scores (mHHS, pain VAS, HOS-ADL, and HOS-SSS). Two patients developed symptoms sufficient to require revision hip arthroscopy for HO excision. After revision hip arthroscopy, both symptomatic patients had improved significantly in all clinical outcomes at the final follow-up. Conclusions HO is a minor complication of hip arthroscopy, but sometimes induces severe pain and functional impairment. Usually, HO forms in the arthroscopic portal or capsulotomy area.

Abstract
BACKGROUND Given that anorexia nervosa (AN) is a life-threatening mental disorder and has poor clinical outcomes, novel effective treatments are warranted, especially for severe and persistent cases. OBJECTIVE To investigate the safety, feasibility, and clinical outcomes of using deep brain stimulation (DBS) of the nucleus accumbens (NAcc) in treatment-refractory AN patients. METHODS A total of 28 women with refractory AN underwent NAcc-DBS and completed this 2-year follow-up study. The clinical outcomes, including body mass index (BMI) and mood, anxiety, and obsessive symptoms, were assessed using a series of psychiatric scales at 6 and 24 months post operation. RESULTS While no fatalities were reported during this study, 1 patient showed device rejection. The most common short-term side effect observed was varying degrees of pain at the incision sites (n = 22), which usually disappeared 3-4 days following the operation. No severe surgical adverse events were observed. Compared to presurgical levels, significant increases in BMI and improvement in psychiatric scale scores were noted during the 6-month follow-up and were maintained at the 2-year review. Finally, a post-hoc analysis revealed that the NAcc-DBS was less effective for weight restoration in patients with the binge-eating/purge subtype of AN than in those with the restricting subtype (R-AN). CONCLUSION Our long-term follow-up study suggests that NAcc-DBS is safe and effective for improving the BMI and psychiatric symptoms of patients with refractory AN. Although NAcc-DBS appears to be more suitable for patients with R-AN, strict inclusion criteria must be applied considering surgery-related complications.

Abstract
Tourette syndrome (TS) is a childhood-onset neuropsychiatric disorder characterized by the presence of multiple motor and vocal tics. TS usually co-occurs with one or multiple psychiatric disorders. Although behavioral and pharmacological treatments for TS are available, some patients do not respond to the available treatments. For these patients, TS is a severe, chronic, and disabling disorder. In recent years, deep brain stimulation (DBS) of basal ganglia-thalamocortical networks has emerged as a promising intervention for refractory TS with or without psychiatric comorbidities. Three major challenges need to be addressed to move the field of DBS treatment for TS forward: (1) patient and DBS target selection, (2) ethical concerns with treating pediatric patients, and (3) DBS treatment optimization and improvement of individual patient outcomes (motor and phonic tics, as well as functioning and quality of life). The Tourette Association of America and the American Academy of Neurology have recently released their recommendations regarding surgical treatment for refractory TS. Here, we describe the challenges, advancements, and promises of the use of DBS in the treatment of TS. We summarize the results of clinical studies and discuss the ethical issues involved in treating pediatric patients. Our aim is to provide a better understanding of the feasibility, safety, selection process, and clinical effectiveness of DBS treatment for select cases of severe and medically intractable TS.

Abstract
Background Patients affected by coxarthrosis may be treated surgically with total hip arthroplasty (THA). During the surgical intervention, the hip joint capsule can be completely removed, performing a capsulectomy. Otherwise it's possible to perform a capsulotomy, which allows for capsular conservation. Since there is no scientific evidence demonstrating the superiority of one method over the other, the choice whether to remove or conserve the capsule is at the surgeon's discretion and both procedures are actually accepted.The purpose of our study is to evaluate the differences in functional activities and proprioception in patients who underwent THA and capsulotomy with capsular conservation versus patients who underwent THA with capsulectomy. Methods In order to compare the two surgical techniques of capsulotomy with capsular conservation and capsulectomy, we created a randomized, controlled, double-blind, single-centre, non-pharmacological, interventional, superiority, parallel-group trial. The primary outcome of our study is evaluated using the HOOS scale (Hip disability and Osteoarthritis Outcome Score). Secondary outcomes are: the proprioceptive sensitivity, the postoperative bleeding, the surgical time, the active range of motion, and the ability to walk, sit and stand. The proprioception study is carried out through active and passive repositioning tests. THA is performed through the minimally invasive direct anterior approach. The evaluation tests are carried out in the 15 days preceding the intervention (T0), at 50-day post-operative (T1), and finally at three months after surgery (T2). Discussion Considering that the hip joint capsule is innervated by proprioceptive nerve endings, while the psuedocapsule that replaces the native capsule following a THA with capsulectomy doesn't have any active neurophysiological role, we hypothesize that capsulotomy with capsular conservation at the time of primary THA may lead to better proprioception and therefore better functional recovery.

Abstract
The operative treatment of stiff shoulder using arthroscopically assisted arthrolysis is indicated in patients with persistent, symptomatic and therapy-resistant movement restrictions. Patients should be informed about relevant risks, supervised rehabilitation and possible recurrences. The surgical procedure provides a precise and controlled semicircular capsulotomy and is followed by an intensive rehabilitation program in order to minimize the risk of recurrences.

Abstract
Background: The role of tractography in gamma ventral capsulotomy (GVC) planning is still unclear. This paper aims to describe the spatial distribution of medial orbitofrontal cortex (OFC) and lateral OFC fibers passing through the anterior limb of the internal capsule (ALIC) and analyze quantitative tractography parameters that differentiate obsessive-compulsive disorder (OCD) individuals from other neurosurgery functional patients (morbid obesity and Parkinson’s disease [PD]). Methods: Twenty patients undergoing functional stereotactic procedures, between 2013 and 2016, were included in this study. OCD patients underwent GVC (single shot 150 Gy and 4-mm collimators). PD and morbid obesity patients were submitted to deep brain stimulation implants. Diffusion tensor image tractography was reconstructed using Brainlab Elements software (Brainlab AG, Munich, Germany). Results: Nine PD, six morbid obesity, and five OCD patients were included with a mean age of 65.4 ± 9.1, 41.0 ± 8.2, and 31.2 ± 5.5, respectively, which are statistically different from each other (P < 0.001). Fourteen patients (70%) were men. A total of 40 cerebral hemispheres were analyzed. Medial OFC fibers are localized more inferior in the ALIC than the lateral OFC fibers in all hemispheres, but the level of intersection and exact topography of fiber bundles are variable among individuals. Both medial and lateral OFC fiber tracts of PD and morbid obesity patients have lower volume than, respectively, medial and lateral counterparts of OCD patients (P < 0.001). Conclusions: Medial and lateral OFC tract fibers have a general standard distribution in the anterior internal capsule (lateral OFC higher than medial OFC fibers). There are differences between obesity, Parkinson, and OCD patients regarding fiber tract statistics.

Abstract
Purpose To present the clinical value of femtosecond laser assisted cataract surgery (FLACS) in eyes with compromised zonules. Observations We present two cases of femtosecond laser assisted cataract surgery (FLACS) in eyes with compromised zonules. Three eyes from two patients with zonular weakness and cataract underwent FLACS (Alcon LenSx Lasers Inc., Aliso Viejo, CA). One patient underwent bilateral FLACS in the setting of spherophakia with zonular weakness. The other patient had Marfan's syndrome with associated ectopia lentis. Laser assisted capsulotomy was achieved in all eyes. One eye had vitreous prolapse during surgery and required an iris-sutured lens. All eyes had a postoperative corrected distance visual acuity of 20/25 or better. Conclusions and Importance FLACS is a safe and effective alternative to conventional phacoemulsification cataract surgery in patients with zonular weakness.

Abstract
"Stiff finger," defined as a finger with decreased range of motion in one or more joints, is commonly found after hand injury and is classified into flexion or extension deformities. Pathogenesis is due to dysfunction in one or more of the following anatomic components: (1) osseous and articular; (2) capsuloligamentous; (3) musculotendinous units; (4) soft tissue and fascia. Evaluation and treatment are based on accurate identification and correction of pathologic structures. The mainstay of treatment is directed hand therapy with exercises and splinting to mobilize stiff joints. Operative interventions are offered after gains from therapy have been exhausted.

Abstract
Background Nd: YAG capsulotomy is the treatment of choice for posterior capsular opacification after cataract surgery. We report a case of corneal perforation following Nd:YAG capsulotomy in a patient with systemic scleroderma. Case Presentation A 69-year-old woman presented with acute onset of blurred vision 2 weeks following Nd:YAG laser capsulotomy for posterior subcapsular opacification. On examination, her best-corrected visual acuity was 1/120, and bio-microscopy revealed a central full-thickness corneal laceration. Conservative treatment consisted of topical ocular antibiotics, cycloplegics, hypotensive drops and a soft therapeutic contact lens. Her final visual acuity improved to 6/18 with resolution of the corneal laceration. Conclusion The possibility of corneal perforation after Nd-YAG capsulotomy in patients with systemic scleroderma and connective tissue disease should be borne in mind when treating such patients.

Abstract
Purpose and hypothesis The aim of this study was to evaluate the hip joint range of motion after different capsular plication. The study hypothesis proposed that capsular plication after hip arthroscopy may reduce hip external rotation and thus prevent the hip joint instability created by arthroscopic capsulotomies. Methods Six fresh frozen human cadavers were studied in the intact state (5 males, 1 females) for a total of 12 non-deformity hips tested. They were fixed to the operating room table using a custom-made apparatus. Three Steinman pins were inserted, the first into ASIS, a parallel pin into the distal femur proximal to inter-epicondylar axis and the third pin into the lateral epicondyle. Simulation of arthroscopic capsulotomies was done progressively with simulation of three capsular plication techniques. The first plication technique consisted of a primary plication shift of the antero-lateral capsule. The distal-medial arm of the iliofemoral ligament was shifted toward the proximal-lateral arm. The second plication technique consisted in adding a longitudinal arm to the capsulotomy, between the lateral arm and the medial arm of the iliofemoral ligament, to create a T-shaped capsulotomy. The resulting two triangular capsular flaps were overlaid onto each other by approximately 5 mm, plicated fully and tighly sutured in a double-breast manner. The third plication technique, called redrapping, consisted in excising the inferior capsular triangular flap (previously made in the second technique), and suturing the latero-anterior superior capsular flap to the medial arm of the iliofemoral ligament, superimposing the capsular edges for closure. External rotation of the hip at 0°, 15° and 30° of flexion were obtained after the capsulotomy and each capsular plication technique to quantify the increase in hip stability after plication. Data were assessed using a two-way repeated measure analysis of variance (ANOVAs) and Student’s T-test when necessary to determine if the change in external rotation was significantly different. Results After capsulotomy, external rotation averaged 26.3°, 29.1° and 31.1° at 0°, 15° and 30° of flexion. With the primary plication shift, external rotation averaged 24.9°, 30.3° and 34.0°. With the two-triangle technique, external rotation averaged 26.1°, 31.9° and 33.3°. With the re-draping technique, external rotation averaged 25.8°, 30.9° and 32.0°. A significant relationship was found between «Plication Technique» and «Angle of flexion» factors for the measured angle of external rotation (P = 0.04). A decomposition of the interaction showed that external rotation decreased at 0° of hip flexion and increased as the hip flexion angle increased. The only significant difference found corresponded to the two triangles technique at 15° flexion (mean difference compared to the non-repaired state = 2.8° ± 3.8° or 8.8% increase in external rotation; P = 0.03). Conclusions Different techniques of capsular plication result in a non-significant increase in hip external rotation when compared to unrepaired capsulotomies. Therefore, special attention should be paid at the time of capsular plication, which could be disadvantageous when done overzealously aiming to increase postoperative stability.

Abstract
BACKGROUND Little is known about the neural mechanism and response variability underlying neurosurgical interventions for intractable obsessive-compulsive disorder (OCD). METHODS Of 81 OCD patients screened for capsulotomy identified in our institutional database, 36 patients with clinical assessment before and after capsulotomy and imaging data (9 of 36 patients without postoperative imaging data used as an independent test group), and 29 healthy control subjects were retrospectively recruited. Twenty of 36 patients (56%) responded to the lesion procedure (determined as a ≥35% reduction in Yale-Brown Obsessive Compulsive Scale [Y-BOCS] score). Seed-based (i.e., ventral and dorsal caudate, medial dorsal thalamus, and ventral and dorsal putamen) resting-state functional connectivity was used to examine alterations in frontostriatal circuitry after capsulotomy. RESULTS The Y-BOCS score significantly decreased (p < .001) after capsulotomy in OCD patients. Functional connectivity between the ventral striatum/nucleus accumbens and the dorsal anterior cingulate cortex was reduced (p < .05, corrected) after the surgical procedure. Moreover, change in connectivity significantly correlated with alteration in Y-BOCS score (r = .41, p = .033). In addition, preoperative connectivity between the dorsal caudate and the dorsal anterior cingulate cortex could differentiate nonresponders from responders and predict changes in Y-BOCS score (R2 = .23, F1,25 = 7.56, p = .011), which was generalized in an independent test group. CONCLUSIONS We demonstrated that restoration of ventral frontostriatal connectivity was associated with clinical improvement in refractory OCD, suggesting a therapeutic mechanism of capsulotomy. Moreover, preoperative variations in dorsal frontostriatal connectivity predicted clinical response, which may offer a predictor of treatment outcome.

Abstract
We report the first case of a patient with severe, intractable Tourette Syndrome with comorbid Obsessive Compulsive disorder, who recovered from both disorders with gamma-knife (GK) stereotactic radiosurgery following deep brain stimulation (DBS). This case highlights the possible role of the internal capsule within the neural circuitries underlying both TS and OCD, and suggests that in cases of treatment-refractory TS and comorbid OCD, bilateral anterior capsulotomy using stereotactic radiosurgery may be a viable treatment option.

Abstract
PURPOSE The aim of the study was to evaluate the effect of capsulotomy as a measure of pain relief and hemarthrosis prevention in the arthroscopic double-bundle anterior cruciate ligament reconstruction. METHODS This was a case control study conducted between April 2013 and Dec 2013, in which 64 patients were enrolled. Capsulotomy was done at the end of the procedure in 31 patients, who were compared with a control group. Pain score (VAS) and grade of hemarthrosis on post-op day 1 and post-op day 2 were compared between the two groups and patients followed up to a minimum of 24 months. RESULTS There was a statistically significant difference (p value < 0.05) in the pain scores and hemarthrosis grade of the capsulotomy group compared to the control group. The mean pain score on post-op day 1 in the capsulotomy group was 2.71 ± 0.97, whereas it was 4 ± 1.22 in the non-capsulotomy group. The difference between the two groups was statistically significant both at day 1 of post-op and day 2 of post-op (p value < 0.05). The difference between the two groups in terms of hemarthrosis grading was statistically significant both at day 1 of post-op and day 2 of post-op (p value < 0.05). The difference between the two groups in terms of thigh circumference measurements was statistically significant both on day 1 and day 2 of post-op (p value < 0.05). CONCLUSION We conclude that capsulotomy is a safe and effective measure of pain relief and hemarthrosis management in arthroscopic ACL reconstruction surgeries.

Abstract
Background To report the negative effect of Nd: Yag (Neodymium-doped: Yttrium Aluminium Garnet) laser capsulotomy on the intraocular pressure (IOP) and the trabeculectomy bleb integrity, in a small series of eyes, both trabeculectomised and pseudophakic, following the laser application for the management of posterior capsular opacification (PCO). Methods This is a retrospective, non-comparative interventional case series study, in which 20 trabeculectomised and pseudophakic eyes from 15 patients, with otherwise well functioning blebs, were presented with uncontrolled IOP, in a variable distance of time following the application of YAG laser capsulotomy. Student paired t-test confirmed a statistically significant difference (P < 0.05) between IOP before Nd: YAG laser capsulotomy (16 mmHg ± 3 mmHg) and the respective one, 2 to 6 months after Nd: Yag capsulotomy (34.5 ± 11 mmHg). Results All of the cases failed to respond to conservative treatment and were successfully managed with the implantation of Ahmed drainage devices. All patients showed flat filtering bleb and uncontrolled IOP (34.5 ± 11 mmHg), under maximum topical treatment, in a period of 2 to 6 months following Nd: YAG laser caspulotomy. The implantation of Ahmed valve proved to be effective treatment for these patients (IOP < 21 mmHg). Conclusions Although Nd: Yag laser capsulotomy is considered a safe surgical procedure and usually is done without second thought, in this series of eyes, it is postulated that it may be responsible for the deregulation of the filtering bleb and subsequent loss of IOP control. We consider that laser capsulotomy should be performed with caution, especially in eyes with previous trabeculectomy. Also close monitoring of the intraocular pressure and assessment of eventual bleb morphology variations in the follow-up period is mandatory. Further studies are needed in order to confirm our findings.

Abstract
The use of femtosecond laser surgery improves the precision and reproducibility of corneal incisions and the capsular opening; it also reduces the amount of ultrasound energy required for lens nucleus work-up. The rate of complications reported so far appears to be low. There are a number of contraindications such as a history of cornea and/or glaucoma surgery and certain anatomical features like deep-set eyes, kyphosis, tremor, and obesity. Visual recovery and refractive results of both techniques are excellent. Comparing laser cataract surgery (LCS) with manual cataract surgery (conventional phacoemulsification) based on meta-analysis currently reveals slight differences in refractive and visual outcome. Both methods are extremely successful and safe. LCS is a technique still on the rise, with its full potential not yet tapped.

Abstract
BACKGROUND Postoperative extension deficits following anterior cruciate ligament (ACL) reconstruction can cause major limitation during daily life. The purpose of this study was to evaluate the efficiency of an all-arthroscopic approach and posterior capsule release for the treatment of persistent knee extension deficits following ACL reconstruction. METHODS Between 2009 and 2013 a total of 10 patients with knee flexion contractures after ACL reconstruction were assessed following an all-arthroscopic approach and posterior capsulotomy. The clinical outcomes were reviewed using the range of motion (ROM), Tegner Activity Level, Lysholm score and visual analogue pain scale (VAS). RESULTS Four women and six men with a median age of 34years (range: 17 to 49years) were included in the study. The median follow-up period was 25months (range: 14 to 69months). The median preoperative extension deficit was 15° (range: 10 to 20°) compared to the normal contralateral knee. Postoperatively at final follow-up the median extension deficit was one degree (range: 0 to five degrees) (P<0.01). The median preoperative Lysholm score improved from 52 (range: 32 to 67) to 92 (range: 84 to 100) postoperatively (P<0.01), while the median Tegner Activity Level improved from three (range: two to six) to six (range: three to seven) respectively (P<0.02). The median VAS status for pain decreased from five (range: one to 10) to one (range: 0 to three) (P<0.01). No complications were observed. CONCLUSIONS Arthroscopic posterior capsulotomy is a safe and effective additional procedure in the treatment of persistent knee extension deficits following ACL reconstruction with excellent results regarding ROM and subjective outcomes.

Abstract
PURPOSE Hip arthroscopy is increasingly used to address hip joint pathology. Iatrogenic instability has been reported as a potential complication, leading to the evaluation of various capsular management strategies. The purpose of this review was to (1) report the techniques used for capsulotomy in hip arthroscopy, (2) understand techniques and indications for capsular closure, and (3) report outcomes based on capsular management strategy. METHODS MEDLINE, EMBASE, and PubMed were searched and screened in duplicate for relevant studies. Data regarding patient demographics, indications, surgical technique, rehabilitation strategies, and complication rates were obtained. Study quality was assessed in duplicate using the Methodological Index for Non-Randomized Studies (MINORS) Criteria. RESULTS Eighty-two studies of primarily level IV evidence (80 %) and of fair quality involving 4504 patients with a mean age of 35 years old (range 1.2-82 years) were included. Fifty percent of patients were male. Mean follow-up was 24.9 months (range 5 days to 13 years). Of 68 studies reporting capsulotomy technique (only 7 % of all otherwise eligible studies), 55 % performed an interportal capsulotomy while 24 % performed a T-capsulotomy. Of 36 studies reporting capsular management strategy post-arthroscopy, 22 % did not repair the capsulotomy, 6 % routinely performed partial repair, and 50 % performed complete repair. Of three studies (206 patients) directly comparing capsular management strategies, only one study found a statistically significant difference between complete and partial repair on the Hip Outcome Score-Sport Specific Subscale, though this difference was less than the minimal clinically important difference (83.6 versus 87.3). The total rate of reported post-operative dislocation, instability, or instability was 0.3 % (5 patients). CONCLUSIONS Technical details regarding capsulotomy and capsular management post-hip arthroscopy are not consistently reported in the literature. Capsulotomies are most often performed using an interportal technique, and more recent studies report routine closure. Overall, post-operative instability is rare and there is no consistent trend for capsular management strategy. Given current evidence, there is little basis on which to establish the relationship between surgical technique and post-operative instability or long-term consequences (e.g., kinematic changes). Thus, while capsular closure/plication may be suitable for specific populations (i.e., dysplasia or laxity), evidence-based indications for capsular repair remain unclear.

Abstract
Posterior capsular opacification (PCO) is common after cataract surgery. Recurrence is very rare after a successful Yttrium aluminium-garnet (YAG) capsulotomy in adults. We report a case of visual axis re-opacification after a successful YAG capsulotomy for PCO in an adult. A 60-year male underwent phacoemulsification with +20.0 D acrylic hydrophobic intraocular lens implantation and silicon oil removal (SOR) five months after a successful retinal detachment repair. He underwent a capsulotomy after two months of surgery; however, the visual axis re-opacified after three more months. A YAG anterior hyaloidotomy resulted into improved vision which was maintained over further follow-up. In a post-vitrectomy pseudophakic eye, compression by silicon oil on the posterior capsule is lost after SOR, causing easier and faster migration of lens epithelial cells from the equator to the centre forming an early PCO. Recurrence is possible due to the proliferation of lens epithelial cells along anterior hyaloid also. This case highlights the infrequent scenario of visual axis re-opacification and therefore has teaching value for residents and trainee doctors, who should be made aware of this occurrence. Patients should be explained about this possibility when undergoing YAG capsulotomy in complicated cases such as this one.

Abstract
INTRODUCTION Posterior Capsular Opacifications (PCO) is a frequent complication of cataract surgery following posterior chamber intraocular lens implantation. Nd -Yag laser capsulotomy is the treatment of choice for PCO and is known to be associated with complications like Raised Intraocular Pressure (IOP), Intraocular lens pitting, intraocular lens cracks, cystoid macular oedema, retinal detachment, corneal burns. Raised IOP is the most common complication and prescribing anti-glaucoma drugs post capsulotomy is a common practise. Our study helps us to anticipate the post procedural IOP rise in specific patients and treat only selected group of patients with anti- glaucoma medications. AIM To study and correlate the effect of energy used and number of shots with post procedural IOP spike following Nd-YAG laser capsulotomy cases. MATERIALS AND METHODS All patients with PCO presenting to Ophthalmology Out Patient Department at Sri Siddhartha Medical College between November 2014 to November 2015 were included. All the patients with glaucoma, uveitis and high myopia were excluded from the study. Data relevant to history, ocular examination and IOP were recorded. RESULTS Significant correlation of IOP spike with the number of Nd- YAG Laser shots delivered was found by One-way ANOVA Post-Hoc Tukeys Test. The p-value was significant for shots more than 40, provided the energy was restricted to 20 mJ and below. Correlation of energy with IOP spike was not significant as found by One-way ANOVA, Post-Hoc Tukey test. Predictability of 2 hours post-procedure IOP regarding persistent IOP rise was significant. CONCLUSION It was observed that all pseudophakic patients may not require anti-glaucoma medication pre, or post Nd YAG laser capsulotomy. Only patients who required more than 40 shots during the procedure would need a close observation and if persistent rise is documented, ocular hypotensives may be advised.

PURPOSE Closed 9.5-mm-diameter endocapsular equator rings (E-rings) prevent posterior capsular opacification (PCO). However, in our research, some highly myopic patients unexpectedly developed late, extensive PCO that required capsulotomy. We also report for the first time how the capsule reacted to neodymium-doped yttrium aluminium garnet (Nd:YAG) laser shots. METHODS Sixty-two eyes (39 patients; average age, 48 ± 13.2 years) were implanted with a closed, square-edged silicone E-ring (outer diameter, 9.5 mm) and an intraocular lens between April 16, 2008, and November 30, 2011. RESULTS During the postoperative, minimal 2-year follow-up, PCO requiring Nd:YAG laser capsulotomy developed in six (9.7 %) of 62 eyes, of which five had -8.75 to -12.5 diopters (D) of myopia preoperatively. The axial lengths of those eyes ranged from 25.86 to 29.97 mm. However, none of the 13 eyes with higher myopia had severe PCO that required capsulotomy. All capsulotomies were performed uneventfully. CONCLUSION The standard 9.5-mm-diameter closed E-ring does not prevent extensive PCO in eyes with preoperative myopia ranging between -8.75 and -12.5 D and an axial length between 25.86 and 29.97 mm. Posterior capsulotomies were performed safely. Further study is needed to determine why PCO did not occur in more high myopic eyes (larger axial length eyes).

Abstract
The hip capsule is a highly complex anatomic structure, which influences normal hip motion and biomechanics. A dynamic stabilizing capsular contribution exists in the iliocapsularis and gluteus minimus, among other musculotendinous structures crossing the joint. Variable types and sizes of capsulotomy are necessary to sufficiently visualize and address the bony and soft tissue pathologic source of symptoms. Unrepaired capsulotomies may leave the hip significantly unstable to variable degrees. Capsular closure is a necessary part of a comprehensive arthroscopic hip preservation procedure. Greater titration of the degree of plication may be performed for patients with risk factors for postoperative instability.

Abstract
The purpose of this article is to analyze and understand the mechanism of action, effectiveness, cost and time benefits, advantages and disadvantages of the femtosecond laser (FSL) assisted cataract surgery. A PubMed search was done using the topic and the keywords. Research shows considerable improvements in corneal incisions, anterior capsulotomy, and phacofragmentation using FSL. We will also discuss and compare FSL with conventional cataract extraction techniques in terms of both short-term and long-term advantages and disadvantages. Limitations of the studies reviewed include small sample size and short-term follow-up. The major dilemma is still considered to be its heavy financial feasibility to date.

Abstract
The term "stiff finger" refers to a reduction in the range of motion in the finger. Prevention of stiff fingers by judicious mobilization of the joints is prudent to avoid more complicated treatment after established stiffness occurs. Static progressive and dynamic splints are considered effective non-operative interventions to treat stiff fingers. Capsulotomy and collateral ligament release and other soft tissue release of the MCP and PIP joint are also discussed in this article. Future outcomes research is vital to assessing the effectiveness of these surgical procedures and guiding postoperative treatments.

Abstract
PURPOSE The purpose of our study is to assess the changes in macular thickness (MT) in diabetic and non-diabetic patients and to research effects of topical ketorolac (Acular®, Allergan, Irvine, CA) on MT change after neodymium:yttrium aluminum garnet (Nd:YAG) laser capsulotomy. MATERIAL AND METHODS This study involved 88 eyes of 88 patients diagnosed as posterior capsule opacification (PCO). Patients were divided into four groups according to presence of diabetes mellitus (DM) and drugs used after capsulotomy. Group 1: Patients with DM using only 0.1% Fluorometholon (FML®, Allergan, Irvine, CA) after capsulotomy (22 patients). Group 2: Patients with DM using 0.5% ketorolac (Acular®) and 0.1 Fluorometholon (FML®, Allergan, Irvine, CA) after capsulotomy (20 patients). Group 3: Patients without DM using only 0.1% Fluorometholon (FML®, Allergan, Irvine, CA) (22 patients). Group 4: Patients without DM using 0.5% ketorolac (Acular®) and 0.1% Fluorometholon (FML®, Allergan, Irvine, CA) (24 patients). A plus-shaped capsulotomy was performed using VISULAS® YAGIII (Carl Zeiss) laser microscope. MT measurement with Cirrus SD-OCT (Carl Zeiss Opthalmic System Inc., Model 400, Dublin, CA, Software 5) were done. Measurements were done before laser, and on the first day, first week, first month, third month and sixth month after laser capsulotomy. We compared the four groups for MT change during 6 months. RESULTS Group 1 involving patients with DM using only 0.1% Fluorometholon (FML®, Allergan, Irvine, CA) after capsulotomy had increased MT at the first week, and the first, third, and sixth month after laser (p < 0.001). Group 3 involving patients without DM using only 0.1% Fluorometholon (FML®, Allergan, Irvine, CA) had increased MT at the first week, and at the first and third month, there was no statistically significant difference at the sixth month (p > 0.05). There was no statistically significant increase in MT during the follow-up period in group 2 involving patients with DM using 0.5% ketorolac (Acular®) and 0.1 Fluorometholon (FML®, Allergan, Irvine, CA) after capsulotomy and group 4 involving patients without DM using 0.5% ketorolac (Acular®) and 0.1% Fluorometholon (FML®, Allergan, Irvine, CA) (p > 0.05). CONCLUSION An increase in MT can be observed after Nd:YAG laser capsulotomy, especially in diabetic patients. Adding topical ketorolac (Acular®, Allergan, Irvine, CA) to topical Fluorometholon (FML®, Allergan, Irvine, CA) therapy after YAG laser capsulotomy can prevent this increase.

Abstract
Femoral neck fractures account for nearly half of all hip fractures with the vast majority occurring in elderly patients after simple falls. Currently there may be sufficient evidence to support the routine use of hip replacement surgery for low demand elderly patients in all but non-displaced and valgus impacted femoral neck fractures. However, for the physiologically young patients, preservation of the natural hip anatomy and mechanics is a priority in management because of their high functional demands. The biomechanical challenges of femoral neck fixation and the vulnerability of the femoral head blood supply lead to a high incidence of non-union and osteonecrosis of the femoral head after internal fixation of displaced femoral neck fractures. Anatomic reduction and stable internal fixation are essentials in achieving the goals of treatment in this young patient population. Furthermore, other management variables such as surgical timing, the role of capsulotomy and the choice of implant for fixation remain controversial. This review will focus both on the demographics and injury profile of young patients with femoral neck fractures and the current evidence behind the surgical management of these injuries as well as their major secondary complications.

Abstract
It has been revealed that posterior capsule opacification (PCO) is the most common delayed complication of cataract surgery. On the other hand, Nd:YAG laser capsulotomy is accepted as standard treatment for PCO. Although, Nd:YAG laser capsulotomy is a noninvasive and safe treatment it carries risk of some complications. Using less total energy and performing smaller capsulotomies are effective choices to decrease complications after Nd:YAG capsulotomy. The purpose of this review is to look through the complications associated with Nd:YAG laser capsulotomy, and the effect of capsulotomy size and used total energy on such complications.

Abstract
OBJECTIVE To determine the effect of posterior capsulotomy on macular thickness, intraocular pressure and endothelial cell loss in pseudophakic patients with posterior capsule opacification using the other eye of every patient as a control. METHODS An observational prospective study was conducted on 31 pseudophakic patients with posterior capsular opacification in one eye, using the other eye as a control. Patients did not suffer any other ocular pathology. All patients were treated by posterior capsular opacification with Nd:YAG capsulotomy, and followed up for a three-month period. The ocular examination included, best corrected visual acuity (BCVA), intraocular pressure (IOP), macular optical coherence tomography (OCT), and endothelial cell assessment (including densitometry, cell size and coefficient of variation, hexagonal cell percentage and pachymetry), which were determined in both eyes before treatment, and one week, one month and 3 months after capsulotomy. RESULTS Generalized estimating equations (GEE) were used to assess the capsulotomy effect adjusted by corresponding baseline measurements and time. No association was found between capsulotomy and IOP (P=.597), macular thickness (P=.085) or ECA (densitometry (P=.422), average size of cells (P=.299), variation coefficient (P=.495), hexagonal cell percent (P=.093) and corneal pachymetry (P=.423). A significant increase of 0.15 Snellen units in BCVA was found during the 3-month follow-up period (P<.001). CONCLUSION This study shows that after Nd:YAG capsulotomy, BCVA improves significantly without any IOP, OCT or ECA changes during the three-month follow-up. Nd:YAG capsulotomy is a safe procedure in pseudophakic patients without any other ocular pathology.
