Abstract
PURPOSE To evaluate which secondary intraocular lens (IOL) implantation technique was more successful in achieving the best postoperative results and refractive outcomes between retropupillary iris-claw IOL (ICIOL) and flanged intrascleral IOL (FIIOL) fixation with the Yamane technique. SETTING Eye Clinic of the University of Trieste, Trieste, Italy. DESIGN Retrospective observational study. METHODS 116 eyes of 110 patients who underwent ICIOL or FIIOL were analyzed. Patients with follow-up shorter than 6 months or with incomplete clinical data were excluded. Collected data included demographics, ocular comorbidity, indication of surgery, intraocular pressure, early (≤1 month) and late (>1 month) postoperative complications, corrected distance visual acuity (CDVA), and manifest refraction at the last follow-up visit. RESULTS 50% (n = 58) of eyes underwent FIIOL and 50% (n = 58) ICIOL implantation for aphakia (n = 44, 38%) and IOL dislocation (n = 72, 62%). No statistically significant differences in demographics, comorbidity, follow-up duration, postoperative complications, and surgical indications were found. The refractive prediction error (RPE) was 0.69 ± 0.94 diopter (D) in the FIIOL group and 0.21 ± 0.75 D in the ICIOL group ( P = .03), indicating residual hyperopia after both techniques. RPE, mean absolute error, and median absolute error were higher in the FIIOL group ( P = .003). ICIOL implantation was more successful in obtaining a RPE between -0.50 D and +0.50 D (52% of ICIOL, n = 30, and 31% of FIIOL, n = 18). CONCLUSIONS Both techniques were effective in increasing preoperative CDVA with no statistical difference between them. Although complication rates did not significantly differ, the FIIOL group exhibited less predictable refractive outcomes. Adjusting the dioptric power of the 3-piece IOL, as performed in ciliary sulcus implantation, to prevent myopic shift, is not recommended.

Abstract
A 78-year-old woman with an ocular history of cataract surgery with a diffractive intraocular lens (IOL) in each eye has developed fluctuating vision, greater in the right eye than the left eye, after 4 years. She has a history of inactive central serous retinopathy and a vision potential of 20/25 + 2 in the right eye and 20/25 in the left eye. She has well-controlled diabetes, hypertension, and hypercholesterolemia. She has enjoyed her spectacle independence for some time and wishes to have her vision restored. On examination, her uncorrected distance visual acuity (UDVA) was 20/50 in the right eye and 20/25 in the left eye and her uncorrected near visual acuity (UNVA) was J3 in the right eye and J1 in the left eye. Intraocular pressures (IOPs) measured 22 mm Hg in the right eye and 18 mm Hg in the left eye. Pupils had limited reactivity with irregularity in the right eye but no obvious relative afferent pupillary defect. Motility and confrontation visual fields were unremarkable in both eyes. Retinal acuity meter was 20/20 in both eyes, and manifest refraction was plano -1.25 × 105 20/40, J3 in the right eye and +0.50 × 20/25, J1 in the left eye. Pertinent findings on slitlamp examination included temporal iris atrophy and transillumination defects greater in the right eye than the left eye, peripupillary pseudoexfoliative changes in both eyes, significant inferior subluxation of a diffractive 3-piece posterior chamber IOL in the capsular bag with lens-pitting peripherally and few central, moderate pseudophacodonesis, and an open posterior capsule in the right eye. In the left eye, she had mild inferior subluxation of a single-piece acrylic diffractive IOL in the capsular bag with moderate pseudophacodonesis and an open posterior capsule (Figure 1JOURNAL/jcrs/04.03/02158034-202403000-00019/figure1/v/2024-02-20T193212Z/r/image-tiff). All other anterior segment findings were unremarkable. On dilated posterior examination, she had a cup-to-disc ratio of 0.50 in the right eye and 0.65 in the left eye without edema hemorrhage or pallor. There were attenuated vessels in both eyes, posterior vitreous detachment in both eyes, and a few small drusen peripherally in both eyes. There was retinal pigment epithelium irregularity and dropout parafoveal in the right eye and subfoveal in the left eye (Figure 2). There was no evidence of macular edema, subretinal fluid, choroidal thickening, or neovascular membranes. The periphery was unremarkable in both eyes.JOURNAL/jcrs/04.03/02158034-202403000-00019/figure2/v/2024-02-20T193212Z/r/image-tiff What testing would you obtain preoperatively to help guide your decision-making? How would you counsel the patient regarding comorbid conditions and expectations?

Abstract
PURPOSE To examine the feasibility and outcomes of a modified technique for the implantation of scleral fixated Carlevale intraocular lens (IOL) (I71 FIL SSF. Soleko IOL Division, Pontecorvo, Italy), and to analyze the occurrence of adverse events. METHODS This is a retrospective observational study conducted revising patients charts from 2018 to 2023. Thirty-five eyes of 33 patients were included. Patients requiring IOL explantation had either IOL dislocation or opacification. The implantation of the Carlevale IOL was performed with the subconjunctival positioning of the anchors without any scleral flap. All maneuvers were performed transconjunctivally. The anatomical outcomes considered were IOL positioning, and the absence of postoperative complications. The functional outcomes analyzed were best correctedvisual acuity (BCVA) and refraction. RESULTS In all the cases, the IOL was well positioned and centered postoperatively. No cases of conjunctival erosion were recorded. The best corrected visual acuity (BCVA) was 0.9±0.6 logMar (mean±standard deviation) preoperatively and 0.5±0.5 logMar (mean±standard deviation) postoperatively. The mean preoperative spherical equivalent was +6.8±7.7 dioptres, while postoperatively it was -1.1±1.6 dioptres. The most frequent procedure associated to secondary IOL implantation was posterior vitrectomy (25 eyes, 71.4%), which was performed with 25-gauge transconjunctival cannulas in the ciliary sulcus. The follow-up period was 24.5±16.9 months (mean±standard deviation). CONCLUSION The described mini-invasive technique for Carlevale IOL implantation is safe and effective. It can be recommended either as a stand-alone operation or associated to concurrent surgical procedures.

Abstract
PURPOSE The purpose of the study was to report the complications of sutureless intrascleral (SIS) intraocular lens (IOL) fixation and its management. MATERIALS AND METHODS A multicenter, retrospective, consecutive interventional case series of patients with intra or postoperative complications after SIS IOL fixation during the technical learning curve of vitreoretinal surgeons from three Taiwanese referral hospitals. The used surgical techniques were the Scharioth technique for intrascleral tunnel fixation, Yamane technique (double-needle scleral fixation), and modified Yamane technique (double-needle flanged haptic scleral fixation). The IOL models and surgical instruments used as well as each patient's ocular characteristics and complication management were recorded. RESULTS Of the eight included patients, the complications of 3 (37.5%) and 5 (62.5%) were noted intraoperatively and postoperatively, respectively. Haptic-related complications, including haptic breakage, slippage, and haptic disinsertion, occurred in six eyes. Other complications included uveitis-glaucoma-hyphema syndrome, retinal detachment, and IOL tilt. For the two patients with haptic slippage, repositioning was achieved using a modified cow-hitch technique that resulted in favorable IOL centration and restored visual acuity. CONCLUSION Most complications surgeons encountered during their early exposure to SIS IOL fixation were haptic related. Surgeons should be aware of such complications to prevent and manage them during surgery. Our modified cow-hitch technique could be used to reposition IOLs with unilateral haptic slippage.

Abstract
Purpose To present a modified technique of 4-point scleral fixation using polymethyl methacrylate (PMMA) 2 eyelets intraocular lens (IOL) with 8-0 polypropylene sutures. Methods A 270-degree conjunctival peritomy is done, and 4 sclerotomies (2 nasal and 2 temporal) are created. Lamellar scleral or clear corneal incision is made at superior site (6 mm wide for sclera or 5.5-6 mm for corneal). A short segment of 8-0 polypropylene is inserted into each eyelet, each thread of the suture is externalized through the sclerotomy site, and the lens is inserted. The suture is tightened evenly, and the knot is rotated and internalized. Scleral incision and conjunctival peritomy are sutured with 8-0 vicryl. Results We have performed this technique in 6 patients with excellent visual outcomes and no reported complications over 1 year of follow-up. This technique has practical advantages including rigid and stable PMMA IOL, high tensile, and slim 8-0 polypropylene suture which is easily internalized and less irritated, and affordable and widely available overall consumables. Conclusion We present a modified 4-point scleral fixation technique for posterior chamber IOL placement using PMMA IOL with 2 eyelets and 8-0 polypropylene as compared to previous studies that used foldable IOL with 4 eyelets and 10-0 polypropylene or Gore-Tex sutures. This procedure has moderate technical complexity, comparable to previously reported techniques with good overall clinical outcomes and several practical advantages, particularly related to the affordability and availability of the consumables.

Abstract
PURPOSE To describe a technique for the replacement of dislocation of plate-haptic trifocal intraocular lens (IOL) through double-suture 4-point flange intrascleral fixation. DESIGN Retrospective, interventional, noncomparative, case series. METHODS A total of 7 eyes of 7 patients with a dislocated plate-haptic trifocal IOL were enrolled for 4-point flange intrascleral fixation with double 7-0 polypropylene suture. Preoperative and postoperative visual acuity, operating time, refractive results, postoperative IOL tilt and decentration, and intraoperative and postoperative complications were recorded. RESULTS The mean postoperative uncorrected distance visual acuity (UDVA) was 0.05 ± 0.06 logarithm of the minimum angle of resolution (logMAR). The mean postoperative uncorrected intermediate visual acuity (UIVA) at 80 cm was 0.09 ± 0.06 logMAR and the mean postoperative uncorrected near visual acuity (UNVA) at 40 cm was 0.06 ± 0.07 logMAR. The mean postoperative residual spherical equivalent values were -0.27 ± 0.39 diopters. The visual function index-14 questionnaire showed that no difficulty was found in >80% of subjects for all tasks. The mean surgical time was 16.23 ± 5.64 min. The mean tilt of IOL was 3.74° ± 1.31° and the mean decentration of the IOL was 0.18 ± 0.09 mm. No important complications appeared. CONCLUSION We have described the technique of 4-point flange intrascleral fixation for plate-haptic trifocal IOL.

Abstract
INTRODUCTION To describe the clinical and refractive outcomes of Yamane transconjunctival sutureless intrascleral intraocular lens (SIS IOL) fixation technique in aphakic and dislocated IOLs. METHODS The aphakic and IOL dispositioned patients who underwent Yamane surgery in Bozyaka Research and Training Hospital were evaluated retrospectively. The demographic data, preoperative & postoperative best-corrected visual acuity (BCVA), spherical equivalent (SE), indication for surgery, additional surgical interventions, complications, the final status of retina, and central macular thickness (CMT) through spectral-domain optic coherence tomography (SD-OCT) were recorded. RESULTS A total of 30 eyes of 30 patients were evaluated. The indication for surgery was aphakia in 24 patients, lens dislocation in 1 patient, and IOL dislocation in 5 patients. The mean age of participants was 64.17 ± 14.69 years, and the mean follow-up was 46.07 ± 7.96 months. The mean BCVA was improved from 0.25 ± 0.22 (-0.94 ± 0.83 log MAR) to 0.49 ± 0.24 in decimals (-0.37 ± 0.27 log MAR) (p:0.041). The mean subjective refraction improved from 10.06 ± 3.10 to -1.45 ± 0.73 D in the final visit (p < 0.05). The mean of cylindrical refraction was -1.22 ± 1.03 D in the postoperative period. At the time surgery, 36.6% of patients required at least one additional surgical procedure. During follow-up period, two (6.7%) out of 30 of patients had retinal detachment, two of the patients (6.7%) occured epiretinal membrane, one of the patients (3.3%) had cystoid macular edema. CONCLUSION Yamane SIS IOL fixation technique is an effective and reliable surgical option in complicated cases that require additional surgical interventions in long-term follow-up.

Abstract
PURPOSE This study aims to investigate the postoperative refractive outcomes in eyes that underwent the flanged intrascleral intraocular lens (IOL) fixation combined with vitrectomy with or without gas/air tamponade. METHODS The eyes were divided into two groups (Group A; eyes that underwent flanged intrascleral IOL fixation with gas/air tamponade, and Group B; eyes that underwent flanged intrascleral IOL fixation without gas/air tamponade). The predicted spherical equivalent (SE) refraction values were calculated using the Sander-Retzlaff-Kraff Theoretical formula. Then, the prediction error was calculated by subtracting the predicted SE refraction from the postoperative objective SE refraction and the absolute prediction error was calculated as the absolute value of the prediction error for each eye. RESULTS A total of 68 eyes were included in the current study. There was a significant correlation between the predicted and postoperative SE refraction in both groups (Group A, r = 0.968, P < 0.0001, Group B, r = 0.943, P < 0.0001, linear regression analysis). The prediction error demonstrated a mild myopic shift after the flanged intrascleral IOL fixation in both groups (Group A, -0.40 ± 0.96 diopter, Group B, -0.59 ± 0.95 diopter). There was no significant difference in prediction error and absolute prediction error between the two groups ( P = 0.44, P = 0.70, Wilcoxon rank sum test). CONCLUSION The postoperative SE refraction after flanged intrascleral IOL fixation was not influenced by gas/air tamponade.

Abstract
Purpose: To report the clinical and anatomic outcomes of a single-stage rescue and sutureless 30-gauge needle-assisted transconjunctival intrascleral fixation of dislocated 3-piece rigid poly(methyl methacrylate) (PMMA) intraocular lenses (IOLs). Methods: This retrospective noncomparative single-surgeon interventional study comprised eyes that had concurrent 23- or 25-gauge pars plana vitrectomy and IOL rescue with sutureless transconjunctival needle-assisted flanged haptic intrascleral fixation. Lamellar scleral dissection for haptic fixation was performed 3 mm posterior to the surgical limbus with 30-gauge needles. Primary endpoints included visual acuity (VA), IOL tilt measured with ultrasound biomicroscopy (UBM), and postoperative complications. Results: The study evaluated 25 eyes of 24 patients. The IOL was successfully refixated in 24 of the 25 eyes. The mean preoperative logMAR VA of 1.21 ± 0.79 SD (median 1.3; Snellen equivalent 20/400) improved to 0.28 ± 0.35 (median 0.14; Snellen equivalent 20/30) postoperatively (P < .0001). The mean IOL tilt measured by UBM (n = 7) was 3.79 ± 3.60 degrees. The mean postoperative follow-up was 348 ± 284 days (range, 7-979 days). Postoperative complications included self-clearing vitreous hemorrhage (n = 9), retinal detachment (RD) (n = 1), cystoid macular edema (n = 3), and corneal edema (n = 3). Three eyes (13%) required additional surgery, 1 for RD and 2 for delayed haptic slippage and secondary IOL tilt causing irregular astigmatism. Conclusions: Intrascleral needle-assisted fixation of dislocated or mobile 3-piece PMMA IOLs is an effective, safe method to restore VA.

Abstract
To report the usefulness of intraoperative real-time adjustment of intraocular lens (IOL) tilt during the intrascleral fixation with intraoperative optical coherence tomography (iOCT) as a clinical evaluation and investigate the factors contributing to IOL tilt using iOCT as an experimental evaluation. Retrospective cohort study and experimental research. As a clinical evaluation, the medical records of 43 eyes of 41 patients who underwent intrascleral IOL fixation combined with real-time iOCT observation were retrospectively reviewed. As an experimental evaluation, in order to investigate the factors contributing to IOL tilt, the four experiments were performed using iOCT. The mean IOL tilt angle (°) at the end of surgery and 3 months after surgery were 1.81 ± 1.15 and 2.10 ± 1.66, respectively (p = 0.46). No apparent intra- or postoperative complications occurred during the follow-up period. The experimental evaluation indicated that the IOL tilt was influenced by the insertion angle of the haptic in the vertical direction. The mean IOL tilt angle (°) was 1.94 ± 0.09, 4.67 ± 0.11, 8.90 ± 0.11, and 15.78 ± 0.85 when the insertion angle of the haptic was 0°, 10°, 27.5°, and 45° in the vertical direction, respectively (p < 0.01). Clinical and experimental IOL tilt assessment using iOCT is interactively useful for better quality surgery and better postoperative outcome.

Two Cases of Atopic Dermatitis Patients With Scleral Perforation After Recurrent Scleritis Induced by Scleral-Sutured Posterior Chamber Intraocular Lens Implantation. Cureus 2023; 15:e40153. [PMID: 37431339 PMCID: PMC10329562 DOI: 10.7759/cureus.40153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/08/2023] [Indexed: 07/12/2023] Open
Abstract
This report describes two cases of atopic dermatitis patients with scleral perforation after recurrent scleritis induced by suture exposure after scleral-sutured posterior chamber intraocular lens (PC-IOL) implantation. The first patient was a 41-year-old man (case 1), and the second was a 46-year-old man (case 2). Both had a history of atopic dermatitis and scleral-sutured intraocular lens (IOL) implantation. Scleritis recurred at the suture site after scleral-sutured IOL implantation in both patients. Although the scleritis was controlled by topical and/or systemic anti-inflammatory drugs, the sclera was perforated in both cases because of exposure of the suture knots (after seven years in case 1 and after 11 years in case 2). In case 1, the superotemporal IOL haptic was also exposed over the conjunctiva, and in case 2, the ciliary body was incarcerated in the scleral hole with deformation of the pupil superonasally. Considering that there were no signs of severe intraocular inflammation, surgical intervention was performed in both cases. In case 1, IOL repositioning was performed with oral prednisolone cover at a dosage of 15 mg/day, starting two weeks prior to the surgery. The steroid dosage was gradually tapered off until two months after the surgery. In case 2, the scleral patch underwent without IOL extraction, and no steroid or immunosuppression cover was administered. There was no recurrence of scleritis after surgery in either case, and visual acuity was preserved in both cases. The scleral perforation that occurred after scleral-sutured IOL implantation in these patients was thought to be the result of recurrent scleritis caused by suture exposure and chronic mechanical irritation by a suture knot. The scleritis subsided without removal of the IOL by moving the suture site of the IOL haptic and covering the suture with a scleral flap or patch graft.

Abstract
PURPOSE To compare the long-term outcomes of sutureless intrascleral fixation of the intraocular lens versus sutured scleral fixation. METHODS The authors retrospectively analyzed the medical records of patients who underwent intrascleral fixation of the intraocular lens using two different techniques: trocar-cannula-based sutureless fixation and sutured scleral fixation. Clinical outcomes were compared before and 1-, 3-, 6-, and 12-month follow-ups after the operation. RESULTS A total of 51 patients were followed over a 12-month period after the operation, including 28 eyes in the sutureless group and 23 eyes in the sutured group. Best-corrected visual acuity and spherical equivalent values reached targeted values faster in the sutureless scleral fixation of the intraocular lens. However, no significant difference was observed between the two groups. For intraocular lens capture, there was a statistically significant difference observed in the incidence of postoperative complications, which was demonstrated by one eye in the sutureless group and seven in the sutured group ( P = 0.009). To exclude the effect of corneal astigmatism, surgically induced astigmatism was calculated based on the astigmatism value 1 year after surgery. It was found that the sutureless technique significantly reduced the occurrence of astigmatism (2.43 ± 1.42 vs. 1.65 ± 0.94, P = 0.031). CONCLUSION In a 1-year follow-up period, the trocar-cannula-based sutureless technique was reliable and effective. Sutureless fixation was associated with fewer postoperative complications and lower surgically induced astigmatism values than those with sutured fixation.

Abstract
BACKGROUND To compare the intraocular lens (IOL) tilt and decentration and visual outcomes of transscleral sutured IOL fixation and sutureless flanged IOL fixation. To investigate the influence of IOL tilt and decentration on internal higher-order aberrations (HOAs) in these two techniques. METHODS Patients who received transscleral sutured or sutureless flanged IOL fixation procedures were included in this prospective, non-randomized, comparative study. Corrected distance visual acuity (CDVA) was measured at baseline and at every postoperative visit for 12 months. IOL tilt and decentration were measured using a second-generation anterior segment optical coherence tomography (Casia2) and internal HOAs were measured using iTrace Visual Function Analyzer at 3 months postoperatively. RESULTS The study included 27 eyes from the transscleral sutured IOL fixation group and 26 eyes from the sutureless flanged IOL fixation group. There was no significant difference in CDVA between the two groups at all time points. The two groups did not differ in refractive difference from the predicted value, corneal endothelial cell loss, IOL tilt, IOL decentration, internal astigmatism or internal HOAs. Vertical IOL decentration significantly correlated with total internal optical aberration (r = 0.288, P = 0.036), total internal HOA (r = 0.440, P = 0.001), internal coma (r = 0.348, P = 0.001), vertical internal coma (r = 0.388, P = 0.004), average height of modulation transfer function (r = - 0.364, P = 0.007) and Strehl ratio (r = - 0.297, P = 0.031). Horizontal IOL decentration significantly correlated with horizontal internal coma (r = 0.312, P = 0.023). CONCLUSIONS Transscleral sutured IOL fixation and sutureless flanged IOL fixation had similar IOL positions and visual outcomes. IOL decentrations correlated with internal HOAs and thus should be avoided.

Abstract
AbstractBackground: Complicated cataract surgery is the main cause of secondary lens implantation surgery. Several approaches have been introduced to face those circumstances. As it concerns scleral-fixated IOLs for the posterior chamber, many types of IOL can be implanted. The aim of article is to review the single piece sutureless scleral fixation Carlevale lens; Methods: Narrative review; Results: Several works described as safe the IOL implantation utilizing the handshake approach, without tactile manipulation, which allows for self-centration and lens firm fixation in uncomplicated surgery. This allows to reduce high order aberration such as astigmatism and coma, with a very good postoperative BCVA Conclusions: Carlevale lens is one of the best option to manage insufficient capsular support.

Abstract
Purpose: We evaluated the utility of peripheral vitrectomy featuring scleral indentation; we compared a group who underwent peripheral vitrectomy to a control group for whom vitrectomy was combined with scleral fixation of intraocular lenses (IOLs) in patients exhibiting IOL dislocations.Methods: From January 2018 to December 2020, 20 eyes of patients evidencing IOL dislocations that underwent total vitrectomy, IOL removal, and IOL scleral fixation were evaluated; peripheral vitrectomy with scleral indentation was performed in 10 patients. All operations were performed by the same surgeon. We excluded patients with follow-up periods less than 6 months, those with a history of retinal and/or glaucoma surgery, and patients with retinal abnormalities or glaucoma that might significantly compromise visual acuity. The postoperative best-corrected visual acuity, intraocular pressure, astigmatism changes, and complications were retrieved from the medical records.Results: Six months after surgery, the best corrected visual acuity was 0.95 (the Snellen measure) in the group who underwent peripheral vitrectomy featuring scleral indentation, and 0.60 in the control group (p = 0.029). The total astigmatism values were 0.48 diopter in the former and 2.80 diopter in the latter group; the difference was significant (p < 0.001).Conclusions: In patients with IOL dislocations who underwent vitrectomy combined with IOL scleral fixation, improvements in visual acuity were further enhanced when peripheral vitrectomy was combined with scleral indentation. Complete removal of the peripheral vitreous may stabilize IOL positioning by the remnant vitreous.

Abstract
PURPOSE To study the safety and efficacy of 25-gauge trocar-assisted flanged intrascleral sutureless IOL fixation in patients with insufficient posterior capsular support. METHODS Five aphakic eyes with capsular insufficiency were included in this prospective interventional case series study, at Dar El Oyoun Hospital, Cairo, Egypt. Twenty five-gauge trocar-assisted flanged intrascleral sutureless technique was used for IOL fixation, in which retinal microforceps were used to capture and externalize both haptics through a scleral tunnel. CDVA, IOP measurements and IOL centralization were reported pre- and one day, one & 3 months postoperatively. Any intra- or postoperative complications were recorded. RESULTS The mean LogMAR CDVA had significantly improved one day, 1 & 3 months postoperatively (0.74 ± 0.1, 0.42 ± 0.07 and 0.26 ± 0.08 respectively, p < 0.001) compared to the preoperative value (1.7 ± 0.17). The mean IOP showed no significant changes along the follow-up period (16.9 ± 0.1; 16.2 ± 1.1; 16.3 ± 0.9 mmHg, p = 0.68, 0.58, 0.89) respectively at 1st day, 1 & 3 months postoperatively) compared to the preoperative measurement (16.4 ± 1.8 mmHg). The IOL was found to be centralized in all cases. No intra- or postoperative complications were encountered. CONCLUSION 25-gauge trocar-assisted flanged intrascleral sutureless IOL fixation is found to be a reliable and effective technique that overcomes Yamane technique's challenges for IOL fixation in cases with posterior capsular insufficiency.

Abstract
INTRODUCTION To introduce a modified technique for primary/secondary intraocular lens (IOL) fixation without corneal incision in vitrectomized eyes. METHODS Consecutive case series who had undergone previous or concomitant pars plana vitrectomy (PPV) to have primary/secondary IOL fixation were prospectively included. A self-sealing scleral incision was made underneath the superior scleral flap, through which the IOL was inserted into the anterior chamber. The suture tied with the IOL passed through the sclera to fix the IOL in the ciliary sulcus. Patients were followed up for at least 3 months. Main outcomes were best corrected visual acuity (BCVA), intraocular pressure (IOP), surgically induced astigmatism (SIA), and intraoperative and postoperative complications. RESULTS A total of 31 patients were included in the study. The mean follow-up time was 5.35 ± 4.14 months. The BCVA (log MAR unit) improved from 0.97 ± 0.58 preoperative to 0.42 ± 0.36 postoperative (P < 0.001). Mean IOP remained unchanged (preoperative IOP 14.03 ± 2.90 mmHg, postoperative IOP 13.26 ± 3.46 mmHg, P = 0.130). The mean SIA was 0.91 ± 0.76 diopters. No obvious intraoperative and postoperative complications were observed. CONCLUSION This method has favorable postoperative visual recovery and IOP control. This modified method could be taken into account as an option by surgeons in vitreoretinal surgery.

Abstract
Purpose “In-the-bag” placement of an IOL is the Holy Grail for any cataract surgeon. However, in the absence of capsular integrity, alternative surgical options to place the IOL must be sought. We aim to report the clinical outcomes and safety profile of scleral-fixated Akreos AO60 intraocular lens implantation using Gore-Tex suture, combined with pars plana vitrectomy. Methods This is a single-center, retrospective case series descriptive study. Electronic clinical records of all patients subjected to scleral fixation of a Bausch and Lomb Akreos AO60 IOL combined with pars plana vitrectomy, between April 1, 2017, and August 1, 2021, were reviewed. Data concerning age, sex, laterality, past ophthalmological history, pre- and postoperative best-available visual acuity, surgical indication, and intra- and postoperative complications were collected. Measured outcomes were the differences in best-available visual acuity and frequency of postoperative complications. Results A total of 37 eyes (20 right eyes and 17 left eyes) from 36 patients (16 females and 20 males) were included in the statistical analysis. The mean age at time of surgery was 72.0 ± 12.4 years. The mean follow-up period was 548.9 days (range 39–1564 days). Globally, the mean best-available logMAR visual acuity improved from 1.61 preoperatively (0.025 decimal equivalent) to 0.57 postoperatively (0.3 decimal equivalent), this difference being statistically significant (P < 0.001). Indications for surgery included aphakia due to complicated cataract surgery (24.3%; n = 9); subluxated IOL due to closed trauma (21.6%; n = 8); PEX-related subluxated IOL (16.2%; n = 6); non-traumatic, non-PEX-related subluxated IOL (18.9%; n = 7); subluxated crystalline lens due to closed trauma (8.1%; n = 3); aphakia due to open-globe injury (5.4%; n = 2); silicone-induced IOL opacification (2.7%; n = 1); and aphakia post-endophthalmitis (2.7%; n = 1). Postoperative complications included transient ocular hypertension (27.0%; n = 10), transient corneal edema (18.9%; n = 7), cystoid macular edema (18.9%, n = 7), self-limited hypotension (5.4%, n = 2), self-limited vitreous hemorrhage (2.7%, n = 1), central retinal vein occlusion (2.7%, n = 1), late retinal detachment (2.7%, n = 1), and Akreos IOL opacification (2.7%, n = 1). No suture-related complications were observed. Conclusion There was a statistically significant improvement in visual acuity after scleral fixation of Akreos AO60 intraocular lens using Gore-Tex suture, with no suture-related problems recorded. This procedure seems to be a valuable alternative for posterior chamber IOL placement when secondary IOL implantation is required.

Abstract
BACKGROUND At present, silicone oil has been widely used in vitrectomy to deal with complex fundus diseases. Usually, cataract extraction is combined with vitrectomy. However, reducing the complications of silicone oil tamponade and facilitating the secondary implantation of intraocular lens (IOL) are still an urgent problem.
AIM To evaluate the clinical effect of vitrectomy combined with peripheral capsule preservation (PCP) in eyes with silicone oil tamponade.
METHODS This single-center retrospective analysis included 70 patients (73 eyes) who underwent vitrectomy and silicone oil tamponade combined with cataract surgery (stage I) between January 2015 and July 2019. All patients underwent selective reoperation for silicone oil extraction and IOL implantation (stage II) more than 3 mo after stage I. These patients were divided into three groups according to the different lens capsule preservation methods: 28 patients (31 eyes) in a whole capsule preserved (WCP) group, 17 (17 eyes) in a capsule absent (CA) group, and 25 (25 eyes) in a peripheral capsule preserved (PCP) group. Intraocular pressure (IOP), best-corrected visual acuity, surgery time, and other complications were recorded at each time point (1 d, 1 wk, and 1 mo after stages I and II).
RESULTS The IOP values were 14.9 ± 8.2 mmHg in the WCP group, 20.3 ± 13.0 mmHg in the CA group, and 14.2 ± 9.7 mmHg in the PCP group (P < 0.05) at 1 mo after stage I operation. Five eyes had IOP higher than 30 mmHg, and one eye in the WCP group appeared to have silicone oil entering the anterior chamber. There was no significant difference in IOP among the three groups at any other time point (P > 0.05). With IOL implantation, visual acuity improved significantly compared to stage I. The incidence rate of posterior capsule opacity was higher in the WCP group than in the other groups (P < 0.001). In the CA group, IOL deviation due to suture relaxation occurred in one case. There was no significant difference in the surgery time among the three groups in stage I (P = 0.618). In stage II, the surgery time of the PCP group and WCP group was significantly shorter than that of the AC group (P = 0.031).
CONCLUSION Preservation of the peripheral capsule in vitrectomy combined with lens removal is a better option. This method has significant advantages in reducing intraoperative and postoperative complications.

Abstract
Purpose To compare the visual outcomes and complications of patients who underwent flanged transconjunctival sutureless intrascleral intraocular lens (SIS IOL) implantation after anterior and pars plana vitrectomy. Methods All patients who underwent flanged transconjunctival SIS IOL fixation using a 27-gauge needle between September 2017 and November 2019 and were followed up for at least six months were evaluated. The cases in which anterior vitrectomy was performed were classified as Group 1, and those that underwent pars plana vitrectomy were classified as Group 2. The best-corrected visual acuity (BCVA), spherical equivalent values, corneal endothelial cell density, and intraocular pressures were compared between the two groups before and after the operation. Intraoperative and postoperative complications were assessed. Results The study included 108 eyes of 108 patients who were included in the study. Group 1 consisted of 48 patients and Group 2 comprised of 60 patients. When the findings between Groups 1 and 2 were compared in the postoperative period, there was no statistically significant difference in terms of the mean intraocular pressure increase, endothelial cell density, BCVA, and spherical equivalent value (P=0.818, 0.601, 0.368, and 0.675, respectively). When all the patients were considered as a single group, the mean spherical value at the sixth postoperative month was 0.3 ± 2.2 D (min-max, (−5.5)–(+6)), the mean cylindrical value was −1.7 ± 2.4 D (min-max, (−9.25)–(+4)), and the mean spherical equivalent value was −0.5 ± 2.3 D (min-max, (−6.5)–(+6)). Conclusion The flanged transconjunctival SIS IOL fixation technique performed using a 27-gauge needle is safe and effective in the patient group with aphakia and lens/IOL dislocation or subluxation. However, in patients planned to undergo flanged transconjunctival SIS IOL implantation, pars plana vitrectomy seems to be a more suitable option than anterior vitrectomy to reduce complications.

Fiore T, Messina M, Muzi A, Tosi G, Lupidi M, Casini G, Marruso V, Cagini C. Comparison of two different scleral fixation techniques of posterior chamber Carlevale lens. Medicine (Baltimore) 2021; 100:e26728. [PMID: 34397876 PMCID: PMC8360456 DOI: 10.1097/md.0000000000026728] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 06/15/2021] [Accepted: 07/01/2021] [Indexed: 01/04/2023] Open
Abstract
ABSTRACT To investigate the surgical outcomes of 2 different scleral fixation techniques of the new single-piece foldable acrylic Carlevale lens (Soleko) and to compare our results with previous reports of the literature.A retrospective, non-randomized comparative study involving 2 series of patients who underwent 2 different scleral fixation techniques of Carlevale lens was performed. Minimum follow-up of 3 months was requested for inclusion in the study. All the patients underwent a standard ophthalmologic examination including best correct visual acuity, measurement of intraocular pressure, anterior segment, and fundus examination. In the first technique (group 1), plugs were externalized through a 23 gauge sclerotomy and placed within 2 scleral pockets. In the second technique (group 2), plugs were externalized through a 25-gauge sclerotomy and covered by 2 scleral flaps. For an estimation of the refractive prediction error, the postoperative spherical equivalent of objective refraction was calculated (IOL Master 750, Carl Zeiss Meditec AG, Jena, Germany). Spectral domain optical coherence tomography (Spectralis HRA+OCT2, Heidelberg Engineering, Heidelberg, Germany) of anterior segment was used to check plugs positioning postoperatively.Twenty-three eyes in group 1 and 9 eyes in group 2 were included. Preoperative diagnosis was aphakia, dislocated posterior chamber intra ocular lens, dislocated lens, anisometropia, Uveitis-Glaucoma-Hyphema syndrome, perforating trauma with dislocated intra ocular lens, and open globe injury with dislocated intra ocular lens. Respectively, in groups 1 and 2, refractive spherical equivalent prediction error was -0,31 ± 0,74 D and -0,27 ± 0,80 D, and postoperative best-corrected visual acuity was 0,42 ± 0,31 logMAR and 0,47 ± 0,45 logMAR. In group 1, 1 eye developed cystoid macular edema, 1 eye vitreous haemorrhage, and 3 eyes showed plugs located outside the scleral pockets under the conjunctiva. Rupture of 1 of the 2 tips of the plug was observed in 1 patient of group 1 during the externalization.Carlevale lens is a scleral fixated intra ocular lens specifically designed for posterior chamber implantation that could be successfully managed without any significant difference between the 2 surgical techniques, and appears approachable for anterior and posterior segment surgeons. A 25-gauge sclerotomy should be preferred with the aim of a sutureless surgery regardless the technique employed.

[PMID: 34327011 PMCID: PMC8310451 DOI: 10.1155/2021/5525064] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 04/11/2021] [Accepted: 07/08/2021] [Indexed: 11/18/2022] Open
Abstract
Purpose To evaluate long-term outcomes and complications of sutured scleral-fixated foldable intraocular lens (IOL) implantation. Design Retrospective study. Methods Patients who underwent sutured scleral-fixated foldable IOL implantation using 10-0 polypropylene suture were followed up for at least 5 years at one Chinese tertiary hospital and two primary hospitals. Results 52 eyes among 48 patients (35 male and 13 female) were evaluated. The mean age (years) was 50.27 ± 20.08 (range: 6 to 81). The mean postoperative follow-up time (months) was 79.70 ± 18.84 (range: 60 to 121). The mean best-corrected visual acuity (BCVA) improved from 0.83 ± 0.69 logarithm of the minimum angle of resolution (logMAR) at baseline to 0.50 ± 0.45 logMAR at the last follow-up visit. There was improved or unchanged BCVA in 44 eyes (84.62%) and reduced BCVA in 8 eyes (15.38%). Mild intraoperative intravitreal hemorrhage was observed in 3 eyes (5.77%). Early postoperative complications included transient elevated intraocular pressure (IOP) in 5 eyes (9.62%) and hypotony in 1 eye (1.92%). Secondary epimacular membrane occurred in 5 eyes (9.62%) and retinal detachment (RD; 3 years postsurgery), subconjunctival suture knot exposure (5 years postsurgery), and persistent elevated IOP (in a GRAVES patient) occurred in 1 eye (1.92%) each. No suture erosion or breakage nor IOL dislocation was observed. No visually threatening IOL tilt or decentration was reported in any patient. Conclusion Sutured scleral-fixated foldable IOL implantation demonstrated satisfactory long-term outcomes and rare suture-related complications. This technology was safe and did not require complicated equipment and is of considerable interest in the setting of aphakia without adequate capsule support.

Abstract
This review aimed to evaluate the cumulative incidence, patient characteristics, predisposing conditions, and treatment outcomes for late in-the-bag intraocular lens (IOL) dislocation. Literature searches in PubMed (MEDLINE), Embase, and Cochrane Library Central database identified 1 randomized clinical trial, 1 prospective case series, 2 prospective cohort studies, and 36 retrospective studies of this condition, which showed that the cumulative incidence was 0.5% to 3%, it occurred on average 6 to 12 years after cataract surgery, and mean patient age was 65 to 85 years. Pseudoexfoliation syndrome, myopia, and previous vitreoretinal surgery were the most common predisposing conditions. Studies indicated that IOL repositioning and IOL exchange provided similar visual outcomes and were equally safe. The long-term visual outcome seemed satisfactory. However, the quality of evidence regarding treatment was in general quite low. More studies of late in-the-bag IOL dislocation are needed, and in particular, different surgical techniques should be included in high-quality clinical trials.

Clinical Characteristics and Visual Outcomes in Patients with Intralenticular Foreign Bodies with Self-Sealing Corneal Penetrating Wounds. J Ophthalmol 2021; 2021:6613205. [PMID: 34239720 PMCID: PMC8241495 DOI: 10.1155/2021/6613205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 05/19/2021] [Accepted: 06/11/2021] [Indexed: 11/17/2022] Open
Abstract
Purpose Siderosis bulbi may occur as a result of retained intralenticular foreign bodies (ILFBs) that were missed during examination in patients with self-sealing wounds and without a significant decrease in visual acuity. This study aimed to explore the clinical characteristics and visual outcomes of ILFBs with self-sealing corneal penetrating wounds. Methods Fifteen eyes of 15 patients with ILFBs and self-sealing corneal penetrating wounds, seen between October 2014 and September 2019, were retrospectively analyzed. Data regarding the patient demographics, clinical features, surgical procedure, and initial and final best-corrected visual acuity (BCVA) were analyzed. Results All patients were male with a mean age of 41 years. The foreign bodies passed through the cornea, sometimes through the iris, through the anterior capsule, and finally localized in the lens. All ILFBs were pointed and metallic objects and were successfully removed with phacoemulsification and posterior chamber intraocular lens (IOL) implantation. Anterior capsule violation was found in three eyes, but no posterior capsule rupture was found. The IOL was placed in a capsule bag in all the cases. The BCVA ranged from 20/200 to 20/25 preoperatively and improved to between 20/32 and 20/20 at the last follow-up visit. The IOLs were well-centered. Apart from posterior capsule opacity in four eyes, no other postoperative complications were found. Conclusions In patients with a pointed metallic ILFB and self-sealing corneal penetrating wounds (with or without cataracts), early diagnosis and removal of the metallic ILFB combined with lens removal and IOL implantation may avoid late complications and achieve good visual outcomes.

Refractive errors after sutureless intrascleral fixation of intraocular lens. Graefes Arch Clin Exp Ophthalmol 2021; 259:3003-3009. [PMID: 34142189 DOI: 10.1007/s00417-021-05268-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 05/29/2021] [Accepted: 06/02/2021] [Indexed: 10/21/2022] Open
Abstract
PURPOSE To determine the difference between the attempted and the achieved postoperative refractive error after sutureless intrascleral fixation of the haptics of an implanted intraocular lens (IOL). PATIENTS AND METHODS This was a retrospective study of the medical charts of patients who had undergone sutureless intrascleral fixation of an IOL. The IOLs were fixed by inserting the haptics into scleral tunnels with or without flanges. The differences between the attempted and achieved postoperative refractive error (spherical equivalent) were determined. The relationships between the surgical options and the differences of the refractive error and degree of astigmatism were also determined. RESULTS Two hundred and twenty-three eyes were studied. There was a myopic shift of - 0.38 ± 1.13 diopters (D). The mean of the differences between the achieved postoperative and the attempted refractive error was 0.89 ± 0.79 D. The achieved refractive error was significantly correlated with the attempted refractive error (P < 0.001, R2 = 0.631). The surgical procedures selected were not significantly associated with the differences between the attempted and achieved refractive error. The size of sclerocorneal incision and presence of sutures were significantly associated with the final degree of astigmatism (P = 0.006 and 0.008, respectively). CONCLUSIONS The postoperative refractive error was significantly correlated with the attempted refractive error after intrascleral fixation of an IOL. The wound construction was associated with the postoperative degree of astigmatism.

FIL-SSF Carlevale intraocular lens for sutureless scleral fixation: 7 recommendations from a serie of 72 cases. MICA study (Multicentric Study of the Carlevale IOL). J Fr Ophtalmol 2021; 44:1038-1046. [PMID: 34148705 DOI: 10.1016/j.jfo.2021.05.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 04/09/2021] [Accepted: 05/17/2021] [Indexed: 11/22/2022]
Abstract
PURPOSE Lacking a standard technique, the surgical management of aphakia without capsular support remains to be optimized. The goal of this study is to analyze results for the Carlevale FIL-SSF intraocular lens and propose surgical recommendations. PATIENTS AND METHODS The P1.5 Collective performed a retrospective analysis, with a minimum follow-up of 6 months, of the records of 72 implantations of the Carlevale FIL-SSF intraocular lens, specifically designed for sutureless scleral fixation in the ciliary sulcus. RESULTS The most common indication was exchange of a posterior chamber intraocular lens (70.8%). The surgery lasted a mean of 53.4minutes due to the creation of scleral flaps. The implant was damaged in 12.5% of cases. Visual acuity was improved in 83.3% of cases. The postoperative spherical equivalent was -0.3 diopters, with no change in corneal astigmatism. The implant was centered and stable in all cases. Two cases (2.8%) of cystoid macular edema were observed and resolved over six months. DISCUSSION A number of advantages of the Carlevale FIL-SSF intraocular lens make it a safe and effective solution for correction of aphakia in the absence of capsular support. It requires a longer than usual surgical procedure, and the implant must be handled with care. From their experience, the authors propose 7 recommendations to accelerate the learning curve. CONCLUSION In light of the results of this study, we propose the Carlevale FIL-SSF intraocular lens as the new standard for the correction of aphakia without capsular support, but other studies are necessary to determine its exact place within the heirarchy of other available techniques.

Secondary Sutureless Posterior Chamber Lens Implantation with Two Specifically Designed IOLs: Iris Claw Lens versus Sutureless Trans-Scleral Plugs Fixated Lens. J Clin Med 2021; 10:jcm10102216. [PMID: 34065508 PMCID: PMC8161112 DOI: 10.3390/jcm10102216] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 05/03/2021] [Accepted: 05/12/2021] [Indexed: 11/19/2022] Open
Abstract
Background. The management of patients with aphakia and/or lack of capsular support remains debated. The sutureless posterior chamber IOL (PCIOL) fixation is a very useful surgical option. The purpose of the study was to compare the early outcomes as well as post-operative best corrected visual acuity, refractive errors and complications of two different techniques of sutureless PCIOL secondary implantation. Methods. Patients who underwent secondary implantation from December 2019 to January 2021 in the Department of Ophthalmology of Creteil Hospital, and in the Granville Ophthalmology Center, were retrospectively included. Eyes implanted with the iris claw lens (Artisan Aphakia IOL model 205, Ophtec BV, Groningen, The Netherlands) were included in group 1, and eyes implanted with a newly developed sutureless trans-scleral plugs fixated lens (STSPFL, Carlevale lens, Soleko, Pontecorvo, Italy) were included in group 2. Results. Twenty-two eyes of 22 patients were enrolled in group 1, and twenty eyes of 20 patients in group 2. No difference was found in visual acuity between two groups (0.35 +/− 0.29 logmar for group 1 and 0.23 +/− 0.51 logmar for group 2) (p = 0.15) at mean post-operative follow up (6.19 +/− 3.44 months for group 1 and 6.42 +/− 3.96 months for group 2) (p = 0.13). Both the mean refractive error (MRE) and induced astigmatism (IA) were greater in group 1 compared to group 2, respectively: the MRE was 0.99 +/− 0.57 vs. 0.46 +/− 0.36 (p < 0.01), and IA was 1.72 +/− 0.96 vs. 0.72 +/− 0.52 (p < 0.01). Conclusions. No significant differences in terms of the recovery of visual acuity were found between the two groups. Group 2 (STPFL) gives better results in our sample due to less post-operative induced astigmatism and less refractive error.

Abstract
PURPOSE To compare the visual outcomes and complication rates of sutureless cannula-based intraocular lens scleral (SCILS) fixation performed with 25-gauge (25 G) versus 27-gauge (27 G) instrumentation. METHODS A retrospective chart review of consecutive cases of eyes without capsular support that underwent SCILS fixation of a three-piece intraocular lens. Sutureless cannula-based intraocular lens scleral fixation was performed by transconjunctival use of either 25-G or 27-G trocar cannulas. During postoperative follow-up evaluations, visual acuity and intraocular pressure were measured, and slit-lamp and indirect ophthalmoscopy examinations were performed to assess for development of known complications. RESULTS A total of 69 eyes underwent 25 G (27 eyes) or 27 G (42 eyes) SCILS fixation. The mean preoperative logarithm of the minimum angle of resolution visual acuity trended toward improvement from 0.95 ± 0.68 (20/178 Snellen equivalent) to 0.67 ± 0.64 (20/94 Snellen equivalent) for 25 G group at 1 year. Similar trend toward visual acuity improvement was seen in 27 G group with a mean preoperative logarithm of the minimum angle of resolution visual acuity of 1.43 ± 0.94 (20/538 Snellen equivalent) improving to 0.86 ± 1.00 (20/145 Snellen equivalent) at 1 year. Statistically significant improvement was seen as early as postoperative week one for 27 G group (P < 0.01), whereas statistically significant worsening was noted at the same time in 25 G group (P = 0.01). There was a statistically significant reduction in intraocular lens displacement (P = 0.01) and need for reoperation (P = 0.01) in 27 G group. CONCLUSION Compared with 25 G SCILS fixation, eyes managed with 27 G SCILS fixation experienced more rapid visual acuity improvement. In addition, there was a lower rate of complications including intraocular lens displacement and need for reoperation.

Abstract
PURPOSE To report the short-term outcomes of a modified small-incision technique for implantation of scleral-fixated intraocular lenses (IOLs) using Gore-Tex sutures. METHODS A retrospective, interventional, consecutive case series was conducted. From June 2019 to February 2020, 10 patients underwent small-incision scleral-fixated IOL implantation using Gore-Tex sutures at a tertiary referral center. Visual and anatomical outcomes and complications were recorded with a minimum follow-up period of 3 months. Surgically induced astigmatism (SIA) and IOL-induced astigmatism were measured. RESULTS The mean follow-up duration (range) was 396 (240-573) days. Best-corrected visual acuity improved significantly from logarithm of the minimal angle of resolution (logMAR) 0.88 ± 0.65 (Snellen equivalent: 20/153) preoperation to logMAR = 0.30 ± 0.51 (Snellen equivalent: 20/40) at final follow-up (P = .008). The estimated SIA and IOL-induced astigmatism were 0.61 diopters (D) ± 0.49D and 0.40D ± 0.36D, respectively. No intraoperative complications occurred. The postoperative complications, which included ocular hypertension (20%), cystoid macular edema (30%), and vitreous hemorrhage (20%), were transient and resolved with topical medication. CONCLUSIONS The modified small-incision technique for implantation of scleral-fixated IOLs using Gore-Tex sutures was well tolerated in all patients, with favorable postoperative visual outcomes and minimal SIA and IOL-induced astigmatism.

Abstract
PURPOSE To compare the clinical outcomes of sutured scleral and sutureless intrascleral fixations of the intraocular lens. METHODS Medical records of patients who underwent sutureless intrascleral fixation (sutureless group) and the conventional sutured scleral fixation (sutured group) were retrospectively reviewed. Patient demographics and the clinical outcomes of the two techniques were compared before and 1, 3, and 6 months after surgery. RESULTS Seventy patients were followed up for 6 months after the surgery: 25 patients in the sutureless group (25 eyes) and 45 in the sutured group (45 eyes). Surgery time was shorter in the sutureless group than that in the sutured group (73.00 ± 15.68 vs. 107.39 ± 25.30 minutes, P < 0.001). The visual acuity gradually improved throughout the postoperative period in both groups, and a faster visual acuity recovery was observed in the sutureless group. The cylindrical error at 6 months after the surgery was significantly lower in the sutureless group than that in the sutured group (-1.33 ± 0.55 vs. -2.29 ± 1.19 diopter, P < 0.001). CONCLUSION Sutureless intrascleral fixation is an effective and reliable surgical technique that provides more favorable visual and refractive outcomes than the conventional sutured scleral fixation method.

Abstract
PURPOSE To evaluate the surgical outcomes and feasibility of a novel approach for scleral-fixation using a single-piece acrylic foldable Carlevale lens (Soleko). METHODS Eighteen eyes of 18 patients with aphakia, dislocated IOL, subluxated lens, anisometropia, perforated trauma, and retinal detachment who underwent IOL implantation with a Carlevale lens were evaluated. All the patients underwent a standard ophthalmologic examination. Anterior segment (AS)-OCT was used postoperatively to check plugs positioning and IOL tilt. RESULTS Mean patients age was 73 ± 19 years. Mean follow-up was 11.2 ± 4.1 months. Mean axial length was 23.7 ± 1.65 mm, white-to-white distance was 11.74 ± 0.40 mm, and axial length was 23.67 ± 1.65 mm. Refractive spherical equivalent prediction error was -0.31 ± 0.71D. Mean IOL tilt was 2.2° ± 1.6° and plugs were placed within the sclera. Five patients had aphakia, five in-the-bag IOL subluxation, three in-the-bag IOL luxation, one high residual myopia after previous verisyse implant, one Uveitis-Glaucoma-Hyphema syndrome, one perforating trauma with phacodonesis, one intraocular foreign body and retinal detachment, two lens subluxation. One eye developed cystoid macular edema which disappeared with topical steroids and FANS. No other complications were observed throughout the follow-up. CONCLUSION Carlevale lens (Soleko) appears to be a viable option for both anterior and posterior segment surgeons in the management of complex cases providing less challenging maneuvers which lead to a good lens self-centration and minimal risk of haptic rupture and/or dislocation. The lens seems to offer a good compartmentalization between the anterior and posterior chamber reducing the risk of an inflammatory response.

Hostovsky A, Mandelcorn M, Mandelcorn ED. Secondary Posterior Chamber Intraocular Lens Fixation Using Flanged Prolene Sutures as an Alternative to an Anterior Chamber Intraocular Lens Implantation. Clin Ophthalmol 2020; 14:3481-3486. [PMID: 33122884 PMCID: PMC7591231 DOI: 10.2147/opth.s276707] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Accepted: 09/28/2020] [Indexed: 12/05/2022] Open
Abstract
Purpose To describe and evaluate the clinical outcomes of the Flanged Prolene Suture intraocular lens fixation (PIF) technique and compare it to anterior chamber IOL (ACIOL) implantation. Design A retrospective comparative review. Methods A retrospective comparative review of consecutive patients undergoing secondary IOL implantation was performed. A comparison between patients that had ACIOL and PIF technique was conducted. The main outcome measures were changes in best-corrected visual acuity (VA), IOL position and complications. Results In the study period, fourteen eyes had ACIOL implantation and ten eyes had PIF surgery. VA acuity for both groups combined improved from 1.27 ± 0.65 logMAR preoperatively to 0.84 ± 0.65 logMAR (P<0.0001). Seventeen patients had VA measurements in the year before the IOL dislocation. In those seventeen patients, VA changed from a baseline of 0.90 ± 0.68 to 0.97 ± 0.61 logMAR in the PIF group (p=0.334) and from 0.54 ± 0.27 to 0.85 ± 0.65 logMAR in the ACIOL group (p=0.145). No intraoperative or early postoperative complications were documented in either group. Two (20%) patients in the PIF group developed CME and one patient developed corneal edema. In the ACIOL group, one patient developed significant CME and two patients developed visual significant corneal edema. Conclusion The PIF technique seems to offer a simple, fast and safe way to fixate an IOL posteriorly. In our experience, the learning curve of the technique is short with a low complication rate and good visual outcomes. ![]()

Mustafi D, Tom E, Messenger WB, Banitt MR, Rezaei KA. Outcomes of sutureless secondary intraocular lens fixation with haptic flanging in a cohort of surgically complex eyes. Graefes Arch Clin Exp Ophthalmol 2020; 259:1357-1363. [PMID: 32945937 DOI: 10.1007/s00417-020-04937-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 08/25/2020] [Accepted: 09/10/2020] [Indexed: 12/30/2022] Open
Abstract
PURPOSE To describe clinical outcomes of secondary intraocular lens (IOL) implantation using sutureless trans-scleral techniques in surgically complex eyes. METHODS Retrospective surgical case series of 45 eyes that underwent secondary IOL implantation using a sutureless haptic flange technique. Demographic data of age, sex, primary diagnosis, best-corrected visual acuity (BCVA), refractive error, intraocular pressure, full ophthalmic exam findings, surgical approach, and any intraoperative complications were noted. RESULTS The most common indication for secondary IOL implantation was aphakia, most commonly after ocular trauma. The primary outcome measures were pre-operative and post-operative BCVA, which revealed recovery of pre-operative vision levels by post-operative week 1 and improved vision by post-operative month 1 (p = 0.03). Secondary outcome measures of target refraction pre-operatively and post-operatively revealed significant reduction in post-operative spherical equivalent to achieve BCVA (p < 0.001). Targeting of the secondary IOLs using Barrett Universal II, Holladay 1, Holladay 2, and SRK/T all exhibited a hyperopic shift post-operatively in post-traumatic aphakic eyes and a myopic shift in the post complicated cataract extraction eyes. No intraoperative adverse events were noted. The most common post-operative complication was transient IOP elevation, with most patients completing 6 months of follow-up. CONCLUSION There is rapid visual rehabilitation and reduction of spherical equivalent correction to attain BCVA in eyes with a history of ocular trauma that undergo secondary IOL implantation using a trans-scleral flange technique. Moreover, this study highlights that a specific IOL power formula can be more predictive of the desired refractive outcome depending on the indication for secondary IOL implantation.

Sutured Intrascleral Posterior Chamber Intraocular Lens Fixation with Ciliary Sulcus Location Guided by Ultrasonic Biological Microscopy: A Retrospective Analysis of Anatomical and Refractive Outcome. J Ophthalmol 2020; 2020:5843410. [PMID: 32587761 PMCID: PMC7293751 DOI: 10.1155/2020/5843410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 04/17/2020] [Accepted: 04/24/2020] [Indexed: 11/29/2022] Open
Abstract
Purpose To report the outcome of sutured intrascleral posterior chamber intraocular lens (PC IOL) fixation with ciliary sulcus location guided by ultrasonic biological microscopy (UBM). Methods Patients who underwent a sutured intrascleral PC IOL fixation were reviewed and divided into four groups. In group 1, the traditional sulcus fixation (2 mm from limbus) of IOL was performed. In groups 2, 3, and 4, UBM was performed before surgery to locate the position of the ciliary sulcus as the haptics insertion position. IOL power was selected by decreasing the calculated value of the IOL power by 1.0 D, 1.0 D, 0.5 D, and 0.0 D, respectively. Results Sixty-one patients (63 eyes) were included in the four groups. After 4.1 ± 3.0 months' follow-up, the postsurgery spherical equivalent (SE) was 0.73 ± 1.86, 0.71 ± 0.84, 1.14 ± 0.45, and 0.07 ± 0.89 diopters (D), respectively. Statistical significance was reached for the postsurgery SE with target refraction between group 1 (p = 0.027, <0.05), group 2 (p = 0.003, <0.01), and group 3 (p = 0.017, <0.05). No significant difference existed for the postsurgery SE with target refraction in group 4 (p = 0.779, >0.05), and the postsurgery SE in group 4 was the nearest to target refraction. Conclusion Intrascleral PC IOL fixation guided by UBM is helpful for locating the ciliary sulcus and satisfactory visual outcomes with a predictable IOL power calculation.
