Corneal Graft Operations
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.
Photorefractive Keratectomy, or PRK, is a type of laser eye surgery for people who suffer from nearsightedness (myopia), farsightedness (hyperopia) or astigmatism. It is similar to LASIK in that it involves using an Excimer laser to reshape the cornea to minimize or eliminate your dependence on eyeglasses or contact lenses. It is different in that unlike LASIK the eye surgeon doesn’t need to use a microkeratome to make a flap, but instead is able to apply the laser directly to the surface of the cornea to achieve the desired vision correction effect.
PRK is better suited for people with thin corneas or certain other corneal abnormalities where using a microkeratome might not be the best choice
