A cornea transplant is an operation used to remove all or part of a damaged cornea and replace it with healthy cornea tissue from the eye of a suitable donor.
A cornea transplant is often referred to as a keratoplasty. It can be used to improve sight, relieve pain in a damaged or diseased eye, and treat emergencies such as severe infection or a damaged cornea surface (perforated cornea).
The latest techniques involve suture less corneal transplant techniques like DALK- Deep Anterior Lamellar Keratoplasty and DSEK- Desemets Stripping Endothelial Keratoplasty.
