Nonarteritic anterior ischemic optic neuropathy after uneventful phacoemulsification: case report.

To report a case of nonarteritic anterior ischemic optic neuropathy (NAION) after uneventful cataract extraction and intraocular lens implantation. Prospective, observational case report and literature review. We report the case history of a 74-year-old woman who underwent phacoemulsification and developed sudden loss of vision on the 13th postoperative day. After complete ocular and systemic evaluation the diagnosis of NAION was made. NAION can be associated with cataract extraction, and surgeons should be aware of this potentially blinding complication.
