Objectives:To evaluate the correlation of cataract surgical simulator and real-life surgical experience and its contribution to surgical training.Materials and Methods:Sixteen doctors in our department were divided into three groups based on their surgical experience. After being familiarized with the device, the participants were evaluated while performing the navigation, forceps, bimanual practice, anti-tremor and capsulorhexis stages. The capsulorhexis stage was repeated five times. Participants were also assessed while performing capsulorhexis again with their non-dominant hand. The influence of repetition and surgical experience on the recorded points was evaluated. P values below 0.05 were considered statistically significant.Results:There was correlation between the participants’ surgical experience and their scores in the capsulorhexis module. Their dominant hand was more successful than the non-dominant hand in capsulorhexis (p=0.004). Capsulorhexis scores increased with repetition (p=0.001).Conclusion:Results achieved with the cataract surgery simulation device correlate with surgical experience. The increase in performance upon repeated practice indicates that the simulator supports surgical training.

“…Multiple groups used VRS performance as measured by the simulator itself to quantify the impact of external conditions: fatigue after a day of live operative cases, distractive arithmetic tasks, beta-blocker use, and caffeine intake. [40][41][42] Preference for and safety of various operative approaches such as hand-versus foot-operated forceps and nondominant hand surgery were similarly assessed. 43,44 Lastly, VRS performance was compared in context of inherent user characteristics including stereoacuity and Kolb Inventory learning style.…”

Introduction Cataract surgery is a fundamental intraocular procedure with a steep learning curve. Virtual reality simulation offers opportunity to streamline this aspect of ophthalmic education by exposing trainees to operative techniques in a controlled setting. Materials and Methods A systematic review of the PubMed database was conducted through December 2019 for English language studies reporting on use of virtual reality simulation in cataract surgery training to assess usefulness. Studies meeting inclusion criteria were examined for pertinent data: study design, number of subjects and live cases, simulator model, training regimen, surgical skills assessed, and overall outcomes. Results Of the 41 analyzed studies, 15 investigated the impact of virtual reality simulation-based training on performance in live surgery or wet laboratories; 20 used simulation as a device for direct assessment of operative proficiency; 6 explored simulation-based training's effect on performance in simulated surgery. Thirty-seven studies employed an iteration of the Eyesi simulator, though methodologies varied widely with a few randomized trials available. The literature endorsed validity of simulator-based assessment and benefits of structured training on live complication rates, operative times, and self- and faculty-perceived competency, particularly in novice surgeons. Discussion The literature surrounding simulation in cataract surgery training is characterized by significant heterogeneity in design. However, most works describe advantages that may outweigh the costs of implementation into training curricula. Collaborative efforts at establishing a structured, proficiency-based cataract surgery curriculum built around virtual reality and wet laboratory simulation have the potential to improve outcomes and enhance future surgical training.
