The use of virtual reality surgical simulator for cataract surgical skill assessment with 6 months of intervening operating room experience
78 ophthalmology residents from both the US and Saudi Arabia were asked to perform a capsulorhexis procedure using the ImmersiveTouch simulator. Before beginning the task, each participant completed a dexterity program to become acclimated to simulator use. Then, each participant completed the capsulorhexis simulation six times, with the lowest performance score being dropped. The four variables measured were circularity, accuracy, fluency, and overall score. Six months later, 40 of the original residents repeated the simulation again. Across the board, performance for all four variables trended towards improvement, with accuracy, fluency, and overall scores showing statistically significant improvement. Residents who had less experience in the OR showed higher levels of improvement than those with more experience, suggesting that simulator use early on can be especially valuable.
“Improved simulator performance correlated with cataract surgery experience in the OR...These findings suggest that the simulator may be used as a measure to index the actual surgical proficiency and OR performance of an individual at two time intervals.”
