This Performance Improvement activity addresses wrong-site surgery and wrong IOL implants, as described by the Ambulatory Surgery Centers (ASC) Quality Collaboration group. EyeNet magazine, published by the American Academy of Ophthalmology, also reported on this concern. Reporters asked a group of leading ophthalmologists to share their stories and strategies. All of these experts knew of specific cases in which simpler errors led to implanting the wrong IOL.
