[PMID: 38491487 PMCID: PMC10943918 DOI: 10.1186/s12909-024-05233-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Accepted: 02/27/2024] [Indexed: 03/18/2024]
Abstract
BACKGROUND To compare the value and efficiency of the three-dimensional (3D) heads-up surgical system and traditional microscopic (TM) system in teaching and learning vitreoretinal surgeries. METHODS Twenty ophthalmologists and scrub nurses were recruited as teachers, and 45 junior ophthalmology residents and trainee doctors, trainee nurses, and medical students were recruited as observers. Each teacher and observer were assigned to both a 3D-assisted and TM-assisted vitreoretinal surgery and then asked to complete satisfaction questionnaires for both surgical systems at the end of each surgery. RESULTS The 3D heads-up surgical system was rated significantly higher in most of the subscales and overall satisfaction score by both teachers and observers (P < 0.05). However, ratings for instrument adjustment were significantly higher in the TM group compared to the 3D group for junior ophthalmology residents and trainee doctors (6.1 ± 1.7 vs. 8.8 ± 1.1, P < 0.001). CONCLUSIONS The 3D heads-up surgical system has great didactical value in the medical education of vitreoretinal surgeries, but it is important to consider the specific needs of different learners when choosing between the two systems. TRIAL REGISTRATION Not applicable.

Abstract
The recent development of high-resolution, heads-up, 3D visualization microscopy systems has provided new technical and visualization options for ophthalmic surgeons. In this review, we explore the evolution of microscope technologies, the science behind modern 3D visualization microscopy systems, and the practical benefits (as well as disadvantages) that these systems provide over conventional microscopes for intraocular surgical practice. Overall, modern 3D visualization systems reduce the requirements for artificial illumination and provide enhanced visualization and resolution of ocular structures, improving ergonomics, and facilitating a superior educational experience. Even when considering their disadvantages, such as those related to technical feasibility, 3D visualization systems have an overall positive benefit/risk ratio. It is hoped these systems will be adopted into routine clinical practice, pending further clinical evidence on the benefits they may provide on clinical outcomes.

Abstract
PURPOSE To describe the experience of our centre (Careggi University Hospital, Florence, Italy) in using a heads-up three-dimensional (3D) surgical viewing system in vitreoretinal surgery, making a comparison with the conventional microscope surgery. METHODS We retrospectively analyzed data taken from 240 patients (240 eyes) with surgical macular diseases (macular hole and epiretinal membrane), retinal detachment or vitreous hemorrhage who underwent vitreoretinal surgeries, by means of the NGENUITY 3D Visualization System (Alcon Laboratories Inc., Fort Worth, TX, USA), in comparison with 210 patients (210 eyes) who underwent vitreoretinal surgeries performed using a conventional microscope. All surgeries were performed with standardized procedures by the same surgeons. We analyzed data over a follow-up period of 6 months, comparing the surgical outcomes (best-corrected visual acuity, anatomical success rate and postoperative complication rate) between the two groups. RESULTS the 3D group included 74 patients with retinal detachment, 78 with epiretinal membrane, 64 with macular hole and 24 with vitreous hemorrhage. There were no significant differences in the demographic and clinical characteristics between the 3D group and the conventional group. We found no significant differences in outcome measures at three and six months follow-up between the two groups (p-value ≥ 0.05 for all comparisons). Surgery durations were similar between the two groups. CONCLUSIONS In our experience, a heads-up 3D surgical viewing system provided comparable functional and anatomical outcomes in comparison with conventional microscope surgery, proving to be a valuable tool for vitreoretinal surgery in the treatment of different retinal diseases.

Comparison of novel digital microscope using integrated intraoperative OCT with Ngenuity 3D visualization system in phacoemulsification. CANADIAN JOURNAL OF OPHTHALMOLOGY 2023; 58:162-167. [PMID: 34562380 DOI: 10.1016/j.jcjo.2021.08.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Revised: 07/18/2021] [Accepted: 08/25/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To compare surgical efficiency, visual and physical comfort, and safety profile of the ARTEVO 800 Digital Microscope (Carl Zeiss Meditec AG, Jena, Germany) and the Ngenuity 3D Visualization System (Alcon Laboratories Inc, Fort Worth, TX) in cataract surgery. DESIGN Cross-sectional study. PARTICIPANTS One hundred consecutive phacoemulsification cataract surgeries performed by five surgeons from June 1, 2020, to November 1, 2020. METHODS For each case, the surgeons answered a 2-section questionnaire (before and after intervention) to collect data on cataract severity or grade, surgical risk, chosen three-dimensional (3D) visualization system, surgical complications, and the visual or physical discomfort experienced during the procedure. RESULTS Each of the 5 surgeons performed 20 surgeries (N = 100) using either the ARTEVO 800 Digital Microscope (N = 50) or the Ngenuity Visualization System (N = 50). Mean duration of the surgical procedure was 17.07 ± 4.80 minutes, and none of the surgeons ever switched to the classical microscope. In addition, 40% of surgeries were considered at low risk, 30% at intermediate risk, and 30% at high risk. The Zoom, Focus, and XY commands were used 1-3 times, respectively, during 76 (p = 0.34), 73 (p = 0.49), and 76 (p = 0.64) interventions. Surgical uncertainty and operative fluency were similar using both systems (p = 0.53 and p = 0.19). We observed 14 intraoperative complications, 9 using Ngenuity and 5 using the ARTEVO 800. Surgeon's visual comfort (p = 0.79), colour or brightness perception (p = 0.82), and visual impairment (p = 0.62) during surgery were similar for both systems. Headache, backache, and other musculoskeletal problems were reported, respectively, after 14 (p = 0.79), 11 (p = 0.99), and 8 (p = 0.44) procedures. CONCLUSION Both the Ngenuity 3D Visualization System (Alcon Laboratories Inc) and the ARTEVO 800 Digital Microscope (Carl Zeiss Meditec AG) provided comparable operative speed and overall surgical comfort during cataract surgery.

Surgery-related characteristics, efficacy, safety and surgical team satisfaction of three-dimensional heads-up system versus traditional microscopic equipment for various vitreoretinal diseases. Graefes Arch Clin Exp Ophthalmol 2023; 261:669-679.

Abstract
PURPOSE To compare the three-dimensional (3D) heads-up surgery with the traditional microscopic (TM) surgery for various vitreoretinal diseases. METHODS A medical record review of patients that underwent 3D heads-up or TM vitreoretinal surgeries was performed from May 2020 to October 2021 in this retrospective case-control study. Main outcome measures included surgery-related characteristics, efficacy, safety, and satisfaction feedback from the surgical team. RESULTS A total of 220 (47.6%) and 242 (52.4%) eyes were included in the 3D and TM groups, respectively. The 3D heads-up system significantly benefits delicate surgical steps, like the epiretinal membrane (ERM) peeling for ERM and internal limiting membrane peeling for idiopathic macular holes (P < 0.05). The 3D heads-up system could facilitate a significantly better visual outcome for pathologic myopic foveoschisis (P = 0.049), while no difference by TM surgery (P = 0.45). For the satisfaction feedback, the 3D heads-up system was rated significantly higher in most subscales and the overall score (P < 0.05). The surgeons' ratings on operating accuracy and the first assistants' rating on operating accuracy and operation cooperation were significantly higher in the TM group than in the 3D group (P < 0.05). Besides that, the 3D heads-up surgery was comparable with TM surgery in the surgery-related characteristics, choice of tamponades, postoperative VA, primary anatomic success, and perioperative complications (P > 0.05). CONCLUSION The efficacy and safety of the 3D heads-up surgery were generally comparable to the TM surgery. The 3D heads-up system could significantly benefit delicate surgical steps and achieve better surgical team satisfaction.

Comparison of Three-Dimensional Surgical System Versus Binocular Microscope for Clear Corneal Incision in Cataract Surgery. Ophthalmol Ther 2022; 11:1589-1600. [PMID: 35749016 PMCID: PMC9244034 DOI: 10.1007/s40123-022-00537-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 05/31/2022] [Indexed: 10/27/2022] Open
Abstract
INTRODUCTION To compare surgical outcomes of 2.2 mm clear corneal incision (CCI) between a three-dimensional (3D) visualization system and traditional binocular microscope (BM) for phacoemulsification and intraocular lens implantation surgery. METHODS In this randomized controlled clinical study, 60 eyes with age-related cataracts were divided into two groups receiving cataract surgery using either a 3D vision system (n = 30 eyes) (3D group) or a binocular microscope (n = 30 eyes) (BM group). We recorded and statistically analyzed surgical parameters and pre- and postoperative ocular parameters. Primary outcomes included the change in endothelial cell density (ECD) and CCI architecture, and secondary outcomes comprised other ocular parameters and surgical parameters. All procedures complied with the tenets of the Declaration of Helsinki. RESULTS Of the 60 eyes randomly assigned between January 5, 2021, and May 9, 2021, 55 (26 eyes in the 3D group and 29 eyes in the BM group) were analyzed. The ECD loss rate was 8.1% in the 3D group and 12.3% in the BM group, but the difference was not statistically significant. Local detachment of Descemet's membrane was seen in 50% (13 eyes, 3D group) and 51.6% (15 eyes, BM group), wound gaping at the endothelial side in 15.4% (four eyes, 3D group) and 10.3% (four eyes, BM group), gaping at the epithelial side in 11.5% (three eyes, 3D group) and 6.9% (two eyes, BM group), and misalignment of the incision in 3.4% (one eye, BM group) 1 day after surgery. These abnormalities improved with time. There was no difference between the 3D group and BM group in terms of other ocular parameters or surgical parameters before and after surgery. CONCLUSIONS Using the 3D surgical system for phacoemulsification and IOL implantation surgery seems to result in similar ECD and CCI conditions as using a conventional binocular microscope. TRIAL REGISTRATION The protocol was registered on ClinicalTrials.gov (NCT04839250).

Abstract
Purpose: To evaluate the results of a pars plana vitrectomy (PPV) combined with cataract surgery for primary rhematogenous retinal detachment (RD) using a three-dimensional (3D) viewing system and a conventional microscope (CM). Methods: Medical reports of 82 patients were retrospectively reviewed: 26 patients were operated on with 3D and 56 patients were operated on with CM. The main outcome measures were visual acuity, duration of the surgery, and the rate of postoperative complications. Results: No statistically significant differences in pre- and postoperative visual acuity were found between both groups. There was significant improvement in the visual acuity in both groups. The best postoperative visual acuity was achieved with SF6 gas tamponade, followed by C3F8 gas and silicone oil in both groups. The duration of the surgery (60 min vs. 55 min) and the rate of postoperative complications (15% vs. 14%) were similar in both groups. Conclusions: The similar postoperative visual acuity and rate of complications detected using 3D and CM indicate that the 3D viewing system may be advantageous in the treatment of rhematogenous RD with PPV combined with cataract surgery, i.e., a complex procedure involving both anterior and posterior segment manipulations.

Abstract
PURPOSE The aim of this study was to compare the complication rates between surgery performed using digital heads-up 3D system (3D group) and a conventional binocular microscope-based system (BM group) in a large series of cataract operations performed by the same surgeon. METHODS This retrospective analysis included a consecutive series of 2,000 cataract operations. The 3D group included n = 1,000 operations performed immediately following the introduction of a 3D system (Alcon Ngenuity). For comparison, the last n = 1,000 operations performed with a binocular microscope were included in the BM group. The 3D system was adapted to the existing microscope so that the microscope optics remained unchanged. The In both groups, the surgical techniques used were either phacoemulsification or femtosecond laser cataract surgery. Complications were recorded and analyzed retrospectively. RESULTS The proportion of femto-laser cataract operations was 19.8% in the 3D group and 18.6% in the BM group. Capsule rupture occurred in 10 eyes (3D: n = 4 (0.4%), anterior vitrectomy: n = 2, pars plana vitrectomy: n = 1; BM: n = 6 cases (0.6%), anterior vitrectomy: n = 4, pars plana vitrectomy: n = 1). A short-term iris prolapse occurred in 3 eyes (3D: n = 2, BM: n = 1). Zonulolysis occurred in 2 eyes (3D: n = 1, BM: n = 1). Overall, there was no statistically significant difference between the two groups (p > 0.5). There was no significant increase in the duration of surgery following the switch to the 3D technique. CONCLUSION In a large series of 2000 eyes, there was no significant difference between 3D and BM surgery in terms of the safety profile during cataract surgery. 3D surgery can, therefore, be used for cataract operations without additional risk.

Abstract
Purpose To compare the efficiency, efficacy, and safety, as well as the educational value, of heads-up (three-dimensional visualization system–assisted) and traditional microscopic cataract surgery. Methods This randomized noninferiority trial enrolled 242 eyes of 201 patients who received femtosecond laser-assisted cataract surgery. The questionnaire study enrolled 26 medical interns and 39 medical students. Patients received surgery under either a three-dimensional visualization system (3D group, 117 eyes) or traditional microscope (TM group, 125 eyes) after random allocation. The primary outcome was surgical time. The noninferiority margin of surgical time was 60 seconds. Secondary outcomes included ultrasound power, phacoemulsification time, visual acuity, intraocular pressure, endothelial cell density, central corneal thickness, complications, and observer satisfaction scores for surgical procedures. Results Surgical time was 462.03 ± 80.36 seconds in the 3D group and 452.13 ± 76.63 seconds in the TM group (difference 9.90 seconds; 95% CI, –9.98 to 29.78; P = 0.365). Visual acuity and other perioperative parameters were comparable between the 3D group and the TM group (all P > 0.05). Incidences of both intraoperative and postoperative complications were low and not statistically different between groups (all P > 0.05). Across all observers, 3D surgery was superior to TM surgery for improving the degree of satisfaction (all P < 0.001). Conclusions The surgical efficiency of heads-up cataract surgery is not inferior to traditional microscopic surgery. Both methods achieved similar efficacy and safety outcomes. Moreover, heads-up cataract surgery showed a significant advantage in medical education. Translational Relevance Our findings show that heads-up cataract surgery has comparable efficiency, efficacy, and safety, as well as superior medical educational value, to TM surgery, which lays the foundation for promoting and popularizing this technology.

Lux study: Contribution of a three-dimensional, high dynamic range, ultra-high-definition heads-up visualization system to a significant delivered light intensity decrease during different types of ocular surgeries. J Fr Ophtalmol 2021; 44:1129-1141. [PMID: 34246497 DOI: 10.1016/j.jfo.2021.01.006] [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: 12/04/2020] [Revised: 12/28/2020] [Accepted: 01/04/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To explore the hypothesis that using a large, three-dimensional (3D), ultra-high-definition (4K), heads-up display (HUD) system in a real-life setting may be associated with a significant reduction in light intensity (LI) delivered during various types of eye surgery. METHODS Single center, post-learning curve observational study of 142 independent consecutive cases: 73 cataracts and 69 vitrectomies (VR). For each group, the only variable setting was the LI. The LI delivered by each source was calibrated in lumens (lm). RESULTS In the VR group, the delivered LI dramatically decreased from the 80% reference to 27.8%±13.2% (P<0.0001) (4.3 to 1.5lm). Among these surgeries, 91.3% needed 40% or less LI (2.3lm). The corneal transparency and quality of pupil dilation showed some correlation with the results. In the cataract group, the difference was even more spectacular, from 80% to 15%±11.3% (P<0.0001) (2.5 to 0.3lm). Among these surgeries, 80.8% required less than 20% LI (0.5lm). The surgical time, LI variations and type of cataract seemed to influence the results, down to 9.6%±5.4% (P<0.0001) (0.22lm) for nuclear cataracts, which represented 63% of the cataract sample. CONCLUSION The digital signal amplification with this HUD system allows comfortable posterior as well as anterior segment surgery despite the decrease in incident light, suggesting an unprecedented reduction in the risk of phototoxicity compared to conventional systems as well as a likely improvement in patient comfort.

Abstract
Purpose: The aim of this study was to evaluate the application and safety of three-dimensional (3D) visualization system in varied anterior segment procedures and Scleral Buckle. Methods: This was a prospective observational study of 313 eyes. Patients undergoing phacoemulsification (PE) with intraocular lens (IOL), trabeculectomies, glaucoma triple procedure (GTP), scleral fixated (SF) IOL, and scleral buckle (SB) were included in the study. Cases were randomly distributed in 3D visualization system (learning and post-learning phase) and conventional microscope group. Parameters studied were complications (intraoperative and early postoperative), surgical outcomes, and surgeon’s perspective on various parameters (through a validated questionnaire) like surgical time, time lag, learning curve, ease of doing various steps and its value as an educational tool, for both groups [Questionnaires 1 and 2]. Results: Complications rates were not different in two groups. Surgical outcomes (anatomical and physiological) were similar in both the groups. Mean duration of surgery in PE+IOL, Trabeculectomy, GTP in learning stage by 3D was significantly higher than Microscope, which became insignificant in postlearning stage. For, SB and SFIOL, duration between two groups were insignificantly different. There was significant learning struggle in PE+IOL, SB, and Trabeculectomy. Image resolution, depth perception, illumination and postural comfort was graded higher for 3D surgery across the stages. Time lag, poor color contrast, and field of view were appreciated during the learning stage. Educational relevance of 3D was higher, as appreciated by resident and nurses. Conclusion: 3D surgery is as safe, faster, and predictable after initial learning struggle. Even in anterior segment procedure, no apparent lag was appreciated after learning curve.

Abstract
Purpose: To compare the outcomes of vitreoretinal surgery in patients with primary and recurrent rhegmatogenous retinal detachment (RRD) with proliferative vitreoretinopathy (PVR) on 3 dimensional digitally assisted visualization system (3D-DAVS) and conventional analogue microscope (CAM). Methods: 68 patients with primary (50) and recurrent (18) RRD with PVR > C1 were included. One group underwent surgery on 3D-DAVS while the other on CAM. The parameters studied included detachment rate, best-corrected visual acuity (BCVA), duration of surgery, mean endo-illumination levels of 23 G (Gauge) micro incision vitrectomy system (MIVS) and microscope and satisfaction of surgeon and observers based on a framed questionnaire. The mean duration of follow up was three months. Results: 68 eyes of 68 patients with median age 52.5 (range 18–68) years were included. 50 had primary RRD and 18 had recurrent RRD. Detachment rate at the end of three months was comparable in both groups of primary (P > 0.99) and recurrent (P = 0.21) RRD. Mean duration of surgery in minutes for 3D DAVS and CAM group was 61.8 (±22.07) and 58.04 (±12.33), respectively, in primary RRD and 37.22 (±10.27) and 36.55 (±5.92), respectively, in recurrent RRD group. Mean endo-illumination in 3D DAVS (14.5%) group was half of that in CAM (34.17%) group. Surgeon and observer satisfaction scores were significantly higher for 3D DAVS group. Conclusion: 3D DAVS is a safe and effective modality or performing VR surgery in RRD with PVR. 3D DAVS allows lower endo-illumination levels provides superior surgeon ergonomics and offers better learning opportunities to the trainees.

Abstract
Heads-up three-dimensional (3D) surgical visualization systems allow ophthalmic surgeons to replace surgical microscope eyepieces with high-resolution stereoscopic cameras transmitting an image to a screen. We investigated the effectiveness and safety of the heads-up NGENUITY 3D Visualization System in a retrospective evaluation of 241 consecutive vitreoretinal surgeries performed by the same surgeon using conventional microscopy (CM group) over a 1-year period versus the NGENUITY System (3D group) over a consecutive 1-year period. We included for study vitreoretinal surgeries for treatment of retinal detachment (RD) (98 surgeries), macular hole (MH) (48 surgeries), or epiretinal membrane (ERM) (95 surgeries). A total of 138 and 103 eyes were divided into 3D and CM groups, respectively. We found no differences in 3-month postoperative rates of recurrence of RD (10% versus 18%, p = 0.42), MH closure (82% versus 88%, p = 0.69), or decrease in central macular thickness of ERMs (134 ± 188 µm versus 115 ± 105 µm, p = 0.57) between the 3D and CM groups, respectively. Surgery durations and visual prognosis were also similar between both groups. We consolidate that the NGENUITY System is comparable in terms of visual and anatomical outcomes, giving it perspectives for integration into future robotized intervention.

Abstract
AIM To evaluate the effectiveness of micropulse laser trabeculoplasty (MLT) for eyes with open angle glaucoma (OAG) under maximal tolerable glaucoma eyedrops and to assess the effect of expertise performing MLT on its clinical effectiveness. METHODS Medical records of 42 consecutive eyes of 34 patients diagnosed with OAG who underwent MLT were retrospectively reviewed. The effectiveness was determined using the Kaplan-Meier survival analysis. Failure was defined as an intraocular pressure (IOP) reduction of <20% from baseline, an IOP >21 mm Hg during two consecutive follow-up visits, or surgical intervention for OAG. To determine the impact of MLT surgical expertise on clinical effectiveness, the eyes were divided into two groups according to whether the procedure was conducted by an experienced specialist (defined as a glaucoma specialist who had conducted at least ten MLT procedures) or a less experienced glaucoma specialist. The difference in expertise was determined using a log-rank test. RESULTS MLT was conducted by three glaucoma specialists. The overall survival rates were 0.76, 0.48, and 0.44 at 1, 3, and 6mo, respectively. The survival rates for MLT performed by a less experienced glaucoma specialist were 0.62, 0.31, and 0.25 (n=21 eyes) at 1, 3, and 6mo, respectively, whereas the survival rates for MLT performed by an experienced glaucoma specialist were 0.90, 0.64, and 0.64 (n=21 eyes) at 1, 3, and 6mo, respectively. The log-rank test showed a significant difference in the survival curves of the two groups (P=0.0061). CONCLUSION The 6-month effectiveness of MLT for controlling IOP is relatively limited in eyes with OAG using maximal tolerable glaucoma eyedrops. However, its effectiveness may be improved if performed by a glaucoma specialist with sufficient MLT experience.

Abstract
Purpose To explore ophthalmic surgeons’ opinions regarding three-dimensional heads-up display (3D HUD) use and investigate musculoskeletal (MSK) complaints among ophthalmologists. Methods Physicians were invited to complete an online questionnaire. Musculoskeletal complaints and data of the HUD system use were correlated with demographic information. We explored surgeons’ feedback on image quality, depth perception, and the educational value of 3D microscopy. Results In this study, the prevalence of self-reported MSK pain was 82.6% (n=132). The pain started after joining ophthalmology practice and significantly improves on weekends and vacations. We found that the pain intensity in non-HUD users is higher than in HUD users, but this correlation was not statistically significant. Sixty-one (84.7%) of HUD system users were satisfied with depth perception, and 27 (37.5%) reported improvement in peripheral acuity. Thirty-seven (51.4%) of the participants believed they perform surgeries better through HUD; this was why most participants (83.3%) recommended its use in surgical training. Conclusion Heads-up display use provides more comfortable sitting positions for surgeons, superior depth perception, and serves as a better educational tool. We believe that adopting this technology may help improve career longevity and productivity.

Abstract
PURPOSE To assess the clinical experience of using a three-dimensional (3D) system for ophthalmic surgical procedures. METHODS We retrospectively analysed video recordings of patients who underwent 3D ophthalmic surgery, using the NGENUITY® 3D visualization system, or traditional microsurgery at our hospital, from August 2017 to February 2018. Patients underwent phacoemulsification or phacoemulsification combined with vitrectomy. Diagnoses, operation type, duration of continuous curvilinear capsulorhexis (CCC), number of forceps nips during CCC and capsulorhexis complications were recorded. Five surgeons and four assistants answered a 3D surgery questionnaire. RESULTS Twenty-six of 46 patients who underwent 3D surgery, and 31 of 51 patients who underwent traditional microsurgery (control group) were enrolled. The mean CCC duration in the study and control groups was 31.2 ± 10.8 and 28.7 ± 13.2 seconds (p = 0.071), and the mean number of forceps nips was 5 ± 2 and 5 ± 2 (p = 0.634), respectively. The anterior capsular rupture rate of phacoemulsification under 3D and traditional conditions was 3.85% (1/26 cases) and 3.23% (1/31 cases), respectively. The complication rate was similar between the two groups (p > 0.999). Four of five surgeons and two of four assistants believed the clarity of 3D surgery was similar or better than that of traditional microsurgery. The occurrence of dizziness (p > 0.999), shoulder and neck pain (p = 0.262), backache (p = 0.471) and visual fatigue (p = 0.347) did not differ significantly between the two methods. CONCLUSION The 3D surgical system facilitated similar operation speed and stability as the traditional microscope and provided reliable support for ophthalmic surgery.

Abstract
Purpose To evaluate the potential value of microscope-integrated optical coherence tomography (MI-OCT) in anterior segment surgical maneuvers. Methods Twenty-four ophthalmology residents, who were randomly and evenly divided into two groups, performed four anterior segment surgical maneuvers (corneal tunnel, scleral tunnel, simple corneal suture, and corneal laceration repair) on porcine eyes with (group B) or without (group A) real-time MI-OCT feedback. All residents performed the maneuvers again without MI-OCT. Results Compared with group A, group B (with MI-OCT) showed better accuracy in the length/depth of the corneal tunnel and the length of the scleral tunnel. However, both groups showed similar performances in the depth of both the simple corneal suture and the corneal laceration suture. When both groups performed the maneuvers again without MI-OCT, group B still showed better results than group A for the length of both the corneal and scleral tunnels. Conclusions Primary results suggest that real-time MI-OCT images are valuable for some anterior segment surgical maneuvers and could be helpful in surgical training. Translational Relevance MI-OCT systems can be valuable in improving accuracy and decision making during anterior segment surgery and will be useful in surgical training.

Abstract
AIM To compare the surgical experience and preferred imaging platform, between digitally assisted vitreoretinal surgery systems (DAVS) and analogue microscope (AM), for performing various surgical manoeuvres. MATERIAL AND METHODS A questionnaire was used to evaluate the experience of surgeons who used DAVS for at least 6 months in the last 1 year. RESULTS Twenty-three surgeons, including 12 fellows, answered the questionnaire. Eighty-two per cent of surgeons got accustomed to DAVS in <10 surgeries. The higher magnification provided by DAVS was perceived as helpful by 87.0% surgeons. Seventy-eight per cent surgeons felt that DAVS provided a bigger field of view. Colours displayed on DAVS appeared unnatural to 39.1%. Difficulty using three-dimensional glasses over spectacles, asthenopia and dry eye symptoms while using DAVS were faced by 17.4%, 17.4% and 21.7% surgeons, respectively. Difficulty in frequent switching between DAVS and AM was faced by 30.4% surgeons. Difficulty in depth perception, hand-eye coordination and performance anxiety while using DAVS was faced by 43.5%, 21.7 % and 30.4 % surgeons, respectively. Majority consultants did not have any imaging platform preference for most posterior segment procedures, while majority fellows preferred DAVS. Majority surgeons preferred AM for anterior segment procedures and complicated situations like small pupil, corneal oedema and surgical surprise(s). Once the surgeons became accustomed to DAVS, none of them had to shift back to AM during any case. CONCLUSION It was easy to adapt to DAVS. DAVS was preferred for performing most posterior segment surgeries. Drawbacks like unnatural colours of the projected image and difficulty in performing anterior segment manoeuvres need to be addressed.
