Atonic pupils after uncomplicated phacoemulsification and intraocular lens implantation.

Objectives: An atonic pupil, defined as a dilated pupil of unknown origin, is a rare postoperative complication of ophthalmic surgery. We studied the incidence of atonic pupils after uncomplicated phacoemulsification and intraocular lens implantation (PEA+IOL) and analyzed the clinical profiles of four cases of atonic pupil.

Methods: We surveyed 54 ophthalmologists in 28 hospitals to determine their clinical experience with atonic pupils after uncomplicated PEA+IOL procedures and the total number of PEA+IOL procedures performed.
