DMEK Surgery In Patiala
What is DMEK surgery and why it is needed?
Descemet’s Membrane Endothelial Keratoplasty (DMEK) is a type of eye surgery that replaces just the inner layer of the cornea. This procedure is used when the cornea’s innermost layer, called the endothelium, becomes cloudy due to disease or injury.
How DMEK Works:
- Selective Removal: The surgery removes only the Descemet’s membrane and the endothelium from the cornea.
- Donor Tissue: These layers are replaced with donor tissue that is very thin, about 10-15 microns thick (thinner than a human hair).
DMEK is different from another procedure called Descemet’s Stripping Automated Endothelial Keratoplasty (DSAEK), which replaces more layers of the cornea. Unlike full-thickness corneal transplants, DMEK focuses only on the innermost layers, leading to quicker recovery and fewer complications.
