DSEK (Descemet’s stripping endothelial keratoplasty) is a type of partial-thickness corneal transplant surgery designed to treat corneal diseases affecting the endothelium, the innermost layer of the cornea. This procedure involves removing the damaged endothelial cells and replacing them with a thin, healthy donor tissue layer. Unlike full-thickness transplants, DSEK uses a smaller incision, resulting in a more stable and secure wound. This approach minimizes the risk of complications and promotes faster healing. DSEK is particularly beneficial for patients with conditions like Fuchs endothelial dystrophy and other endothelial disorders, providing a targeted and effective treatment option.
