Novel Technique for Improving Graft Unfolding in Vitrectomized Eyes Using a Temporary Diaphragm in Descemet Membrane Endothelial Keratoplasty

Purpose: To describe a new surgical technique for performing Descemet membrane endothelial keratoplasty (DMEK) using a temporary hydrophilic methacrylate sheet in the anterior chamber in cases of previous vitrectomy with complete removal of the vitreous body. Methods: Medical records were reviewed for baseline and follow-up best spectacle-corrected visual acuity, endothelial cell count, and indication for DMEK using a temporary hydrophilic methacrylate sheet. Operative notes were analyzed in all cases to identify any specific intraoperative event. Results: Seven eyes of 7 patients were included in this analysis. Mean age was 65.7 ± 18.2 years, and the mean follow-up duration was 11.5 months. All 7 patients had previously received pars plana vitrectomy with complete vitreous removal. All patients were pseudophakic. For 5 patients, it was their first DMEK surgery and 2 patients had DMEK surgery for a second time, due to a failed outcome in previous surgery. Best spectacle-corrected visual acuity improved from 1.5 ± 0.5 logMAR before surgery to 0.76 ± 0.37 logMAR after surgery during follow-up (P
