Descemet Membrane Endothelial Patching: Selective Endothelial Replacement in Eyes With Localized Endothelial...

Descemet membrane (DM) endothelial keratoplasty is considered the gold standard for treating corneal endothelial decompensation and is a true like-for-like replacement. Not all causes of endothelial dysfunction are global, with conditions such as viral endotheliitis affecting discrete populations of endothelial cells. In this study, endothelial grafts matching the area of dysfunction were produced to preserve healthy host cells and limit the immunological burden of new grafts. We have termed this modified DM endothelial keratoplasty procedure DM endothelial patching.
