Abstract

Purpose:The aim of this study was to report progressive corneal clearance and endothelial cell repopulation after a Descemet membrane endothelial keratoplasty graft that was partially folded over on itself in a pseudophakic patient without endothelial dystrophy.Methods:Retrospective case report.Results:A 75-year-old man without Fuchs dystrophy underwent cataract extraction on his right eye in 2007, and 5 years later, Descemet membrane endothelial keratoplasty was performed for pseudophakic edema in the same eye at another center. On presentation at our institution, a graft that is partially folded over on itself was observed in the right eye, leaving about 2/3 of donor endothelium correctly exposed. The graft was only attached in the lower part of the cornea. We observed progressive clearance of the entire cornea within 7 months with reendothelialization of the entire cornea. Good visual acuity was achieved, with no evidence of recurrent corneal edema.Conclusions:Endothelial cell migration and repopulation in the presence of a folded attached endothelium graft may occur, resulting in corneal clearance and improved visual outcome. This could happen in patients with pseudophakic edema without congenital endothelial dystrophy.
