PURPOSE: To investigate the effect of virtual reality proficiency-based training on actual cataract surgery performance. The secondary purpose of the study was to define which surgeons benefit from virtual reality training.

DESIGN: Multicenter masked clinical trial.

PARTICIPANTS: Eighteen cataract surgeons with different levels of experience.

METHODS: Cataract surgical training on a virtual reality simulator (EyeSi) until a proficiency-based test was passed.

MAIN OUTCOME MEASURES: Technical performance in the operating room (OR) assessed by 3 independent, masked raters using a previously validated task-specific assessment tool for cataract surgery (Objective Structured Assessment of Cataract Surgical Skill). Three surgeries before and 3 surgeries after the virtual reality training were video-recorded, anonymized, and presented to the raters in random order.

RESULTS: Novices (non-independently operating surgeons) and surgeons having performed fewer than 75 independent cataract surgeries showed significant improvements in the OR-32% and 38%, respectively-after virtual reality training (P = 0.008 and P = 0.018). More experienced cataract surgeons did not benefit from simulator training. The reliability of the assessments was high with a generalizability coefficient of 0.92 and 0.86 before and after the virtual reality training, respectively.

CONCLUSIONS: Clinically relevant cataract surgical skills can be improved by proficiency-based training on a virtual reality simulator. Novices as well as surgeons with an intermediate level of experience showed improvement in OR performance score.
