Three-quarter DMEK in eyes with glaucoma draining devices to avoid secondary graft failure.

Purpose: To present a case series of a modified three-quarter Descemet's membrane endothelial keratoplasty (3/4-DMEK) technique to treat pseudophakic bullous keratopathy in the presence of a glaucoma drainage device (GDD) tube in the anterior chamber by reducing the risk of donor endothelial damage due to absence of donor endothelial cells overlying the GGD tube area.

Methods: In this prospective case series, four eyes of three patients with stable glaucoma underwent 3/4-DMEK surgery for pseudophakic bullous keratopathy after GDD insertion. The patients were followed up to 24 ± 2.

Intrastromal Descemet Membrane Transplantation as a Potential Alternative to Bowman Layer Inlays in Eyes With Advanced Keratoconus.

Herein, we report the outcomes of intrastromal Descemet membrane (DM) transplantation in corneas with advanced keratoconus. Three eyes (three patients) showed advanced keratoconus. No eye underwent prior UV-cross-linking or any other ocular surgery.

Five Keratoplasties From One Donor Cornea.

Purpose: To describe the feasibility of same-day, consecutive use of a single donor cornea in 5 patients with corneal pathology, who required anterior lamellar and endothelial keratoplasties.

Methods: Descemet membrane (DM) with endothelium was completely stripped from a single corneoscleral button and punched out from the endothelial side with a circular, standard punch. Using a custom-made punch for linear cutting of DM, we obtained 4 quarter-grafts (Q-graft).
