What does this procedure involve?

DSAEK (Descemet Stripping Automated Endothelial Keratoplasty) replaces only the diseased innermost layer of the cornea—the endothelium—with a thin donor graft. During surgery, your surgeon removes the damaged endothelial layer and attaches the donor tissue using an air bubble. This technique preserves most of your cornea's structure, leading to faster visual recovery and lower risk of rejection compared to full-thickness transplants.
