Double bubble pneumo-descemetopexy for the management of Descemet membrane detachment: An innovative technique

Abstract

A 62-year-old woman was referred with poor vision following manual small incision cataract surgery. On presentation, the uncorrected distance visual acuity in the involved eye was 3/60, whereas slit-lamp examination revealed a central corneal edema with the peripheral cornea relatively clear. Direct focal examination with a narrow slit upper border and lower margin of detached rolled up Descemet's membrane (DM) could be visualized. We performed a novel surgical approach, “double-bubble pneumo-descemetopexy.” The surgical procedure included unrolling of DM with “small air bubble” and descemetopexy with “big bubble.” No postoperative complications were observed, and best corrected distance visual acuity improved to 6/9 at 6 weeks. The patient had a clear cornea and maintained BCVA 6/9 during 18 months at follow-up. Double-bubble pneumo-descemetopexy, a more controlled technique, provides a satisfactory anatomical and visual outcome in DMD without the need for endothelial keratoplasty (Descemet's stripping endothelial keratoplasty or DMEK) or penetrating keratoplasty.
