DSEK is a partial-thickness cornea transplant procedure that involves selective removal of the patient's Descemet membrane and endothelium, followed by transplantation of donor corneal endothelium and donor corneal stroma. In DMEK, no stroma is transplanted.
Who is Partial Corneal Transplant for?
The procedure is used to treat corneal swelling or edema in the setting of endothelial dysfunction. A few causes may be Fuchs corneal dystrophy, pseudophakic bullous keratopathy, endothelial failure in the setting of prior intraocular surgery, or a previous failed corneal transplant.
What to expect
A partial corneal transplant offers many advantages over full-thickness transplantation. It is a safer and shorter surgical procedure. It has relatively rapid healing time and visual rehabilitation. Like a full-thickness transplant, it requires lifelong care with close follow-up and use of topical drops. Rejection can still occur with a DSEK, and one must seek care in case of redness, light sensitivity, and blurred vision.
