A minor variation to DMEK is the Descemet Membrane Automated Endothelial Keratoplasty (DMAEK), ... This page was last edited on 2 October 2024, at 16:48 (UTC).
There is currently limited data on long-term survival of DMEK grafts however the early indications are very positive. An upcoming systematic review will seek to compare the safety and effectiveness of DMEK versus DSAEK in people with corneal failure from Fuchs' endothelial dystrophy and pseudophakic bullous keratopathy.

Copper disposition on corneal Descemet's membrane. Significant damage to the membrane may require a corneal transplant. Damage caused by the hereditary condition known as Fuchs dystrophy (q.v.)—where Descemet's membrane progressively fails and the cornea thickens and clouds because the exchange of nutrients/fluids between the cornea and the rest of the eye is interrupted—can be reversed by ...
Bullous keratopathy, also known as pseudophakic bullous keratopathy (PBK), is a pathological condition in which small vesicles, or bullae, are formed in the cornea due to endothelial dysfunction.
The corneal endothelium is a single layer of endothelial cells on the inner surface of the cornea.It faces the chamber formed between the cornea and the iris. The corneal endothelium are specialized, flattened, mitochondria-rich cells that line the posterior surface of the cornea and face the anterior chamber of the eye.
