Pre-Descemet’s Endothelial Keratoplasty (PDEK), Complicated by Dislocation of the IOL into the Vitreous. Case Report

Abstract

This paper presents a case report of Pre-descemet’s endothelial keratoplasty (PDEK) performed on a 72-year-old patient diagnosed with bullous keratopathy, artiphakia, operated open-angle IIIА glaucoma. PDEK is a method of endothelial keratoplasty in which the non-functioning endothelial layer with Descemet’s membrane is replaced with a donor material consisting of Dua’s layer, Descemet’s membrane and endothelium. In the early postoperative period the IOL dislocated into the vitreous body. Both the technique of posterior lamellar keratoplasty and the surgical tactics that were successfully applied in this situation are described in detail. Clinical and functional results were studied with a follow-up period of 6 months.
