Ischemic optic neuropathy following secondary intraocular lens implantation

Ischemic optic neuropathy occurred 10 days after secondary implantation of an intraocular lens in an otherwise healthy 50-year-old man who had undergone two other previously successful cataract operations. General anesthesia was used and postoperative intraocular pressures were normal. Postcataract extraction ischemic optic neuropathy is compared and contrasted to nonarteritic ischemic optic neuropathy occurring in phakic patients.
