BACKGROUND AND OBJECTIVES: Ophthalmology trainees commonly learn laser procedures on live patients. A simulator for learning peripheral iridotomy (PI), posterior capsulotomy, and retinopexy may improve patient outcomes.
MATERIALS AND METHODS: A model eye with artificial tissues was designed. The tissues reacted to laser similarly to human tissues. Inexperienced (n = 6; first-to third-year residents) and experienced (n = 7; fourth-to fifth-year residents and staff) ophthalmic personal were compared on performance of the above laser procedures.
RESULTS: The inexperienced group required more shots (P = .04) and caused more lens markings (P = .04) during capsulotomy and had more incomplete retinopexy results (P = .04) than the experienced group. The groups did not differ in total shots for PI, average power for retinopexy, or the total time required for any of the procedures.
CONCLUSION: Our model effectively simulates common ophthalmic laser procedures and is practical for the training of ophthalmology residents.
