PURPOSE To investigate the correlation between performance on a virtual reality simulator and real-life cataract surgical performance. SETTING Nine ophthalmology departments in Denmark and Copenhagen Academy for Medical Education and Simulation, Copenhagen, Denmark. DESIGN Prospective multicenter study. METHODS Cataract surgeons with different experience levels were included. The participants performed 3 consecutive video-recorded phacoemulsification surgeries that were rated by masked raters using the Objective Structured Assessment of Cataract Surgical Skills (OSACSS) scoring system. Thereafter, the participants performed a previously validated test on an Eyesi virtual reality simulator. Primary outcomes were the mean OSACSS score from all 3 surgeries and the simulator score from the participants' first repetition of the performance test. RESULT Nineteen surgeons participated. There was a statistically significant correlation between the simulator performance score and the mean OSACSS score across all experience levels, with a Pearson correlation of 0.65 (P = .003, R2 = 0.42). CONCLUSION Simulator performance was significantly correlated with real-life cataract surgical performance.

虚拟现实性能与现实白内障手术性能的相关性。

目的研究虚拟现实模拟器的性能与现实白内障手术性能之间的相关性。设置丹麦的9个眼科部门和丹麦哥本哈根的哥本哈根医学教育与模拟学院。设计前瞻性多中心研究。方法包括具有不同经验水平的白内障手术医师。参加者连续进行了3次视频记录的超声乳化手术，这些手术均由戴口罩的评分者使用白内障手术技能的客观结构评估（OSACSS）评分系统进行评分。此后，参与者在Eyesi虚拟现实模拟器上执行了预先验证的测试。主要结果是所有3个手术的平均OSACSS得分和参与者首次重复进行性能测试的模拟器得分。结果19名外科医生参加了会议。在所有体验水平上，模拟器性能得分与平均OSACSS得分之间在统计上均具有显着相关性，皮尔森相关性为0.65（P = 0.003，R2 = 0.42）。结论模拟器的性能与现实生活中的白内障手术性能显着相关。
