DSAEK (Descemet's Stripping Automated Endothelial Keratoplasty)

Descemet’s Stripping Automated Endothelial Keratoplasty (DSAEK)



This newer technique of partial-thickness (posterior lamellar) corneal transplantation is used to treat corneal edema resulting from diseases of the endothelium, the innermost layer of the cornea. DSAEK is a highly refined technique that replaces just the endothelial layer of the cornea, allowing surgeons to target the specific cause of the patient’s vision loss. In the DSAEK procedure the damaged cells are stripped from the patient’s eye and replaced with a very thin back portion of a donor cornea. This procedure allows your surgeon to replace only the damaged area of cornea, allowing a more precise treatment and faster recovery. Your surgeon uses an air bubble technique to hold the new tissue in place in the eye so that no sutures are needed. A large proportion of corneal transplants are performed each year in the United States for corneal endothelial failure as in Fuchs' corneal endothelial dystrophy and corneal edema after cataract surgery. Many corneal diseases previously requiring a full-thickness, traditional corneal transplant can now be treated with this newer surgical technique. Advantages of this technique include a more rapid recovery of vision after surgery, a smaller surgical wound and ability to achieve optimal vision after surgery with glasses instead of a contact lens.
