DMEK & DSEK: Endothelial Corneal Transplant Explained
When the problem lies in the cornea’s thin innermost layer — the endothelium — there is no need to replace the whole cornea. Endothelial keratoplasty (DSEK and the newer DMEK) swaps out just that delicate layer, restoring clarity with a small incision and faster recovery.
Why the endothelium matters
The endothelium acts as a pump that keeps the cornea clear. When it fails — most often in Fuchs’ dystrophy or after some eye surgeries — the cornea swells and vision turns hazy, often worse in the mornings.
DSEK vs DMEK
- DSEK transplants the inner layer with a thin support layer of tissue.
- DMEK transplants only the ultra-thin membrane and cells — giving, in suitable eyes, sharper vision and faster recovery, with a slightly more delicate technique.
Recovery
These are small-incision procedures. A gas or air bubble is often placed to hold the new layer in position, so you may be asked to lie face-up for a period afterwards. Vision typically improves over weeks.
Frequently asked questions
Is DMEK better than DSEK?
DMEK can give crisper vision and faster recovery for suitable eyes, but DSEK remains an excellent, sometimes more practical option. The right choice is individual.
Why do I have to lie on my back after surgery?
An air or gas bubble supports the new layer against your cornea; positioning face-up helps it attach in the first hours to days.
