What steps can we take to ensure that we operate on the proper eye and use the proper lens implant? Put another way, how can we reduce or eliminate potential "system error" in cataract surgery? At Premier Eye Care & Surgery, we have developed a 10-step eye identification system that takes into account that medical errors result from a chain of events, not just a single cause, and the elements seldom all come together at the same time. From the pre-operative verification process to marking the surgical site with color-coded stickers, our system actively involves the patient and builds in so many checks that the chance of the wrong-eye and/or wrong-implant surgery is remote.
