An estimated 24 million Americans have cataracts, making cataract removal and intraocular lens insertion one of the most common surgeries performed in the United States. Cataract surgery is safe, and serious injuries rarely occur. So when an increase in reports of Serious Events related to cataract procedures occurred in one year in Massachusetts, the Betsy Lehman Center for Patient Safety responded. The Center collaborated with a number of state and professional agencies, formed an expert panel, and consulted with the Pennsylvania Patient Safety Authority. The Authority found that from July 1, 2004, through June 30, 2015, Pennsylvania acute care facilities reported 4,307 events related to cataract procedures and 23 wrong-site anesthesia eye injections. Since July 2004, reporting of intraocular lens procedure-related events, which includes near misses and good catches, has steadily increased while the number of incorrect intraocular lens implant events has decreased. The Authority estimates the incidence of cataract-related surgical confusions in Pennsylvania at 61.8 per 1 million procedures for the July 1, 2004, through June 30, 2015, period. In response to a rising trend of intraocular lens-related reports, increased vigilance towards prevention is necessary. Active participation by engaged staff in executing the Universal Protocol--including engaging the patient--and use of an ophthalmology-specific perioperative checklist remain the recommended best practices to prevent wrong eye identification, incorrect lens implantation, and wrong-site anesthesia eye injections.
