Corneal Transplantation

The cornea is a thin mirror-like membrane that is situated in front of the iris and pupil of the eye. It is the cornea that enables us to see by focusing the light that enters the eye.

What is Corneal Transplantation?

Sometimes due to an injury or a disease, there may be some damage to your cornea. In such a situation with the help of a corneal transplant, your doctor may be able to improve or restore your vision. The central part of the cornea is taken out and replaced with a smaller-sized healthy cornea obtained from a donor. As an outpatient procedure, this surgery is generally recommended only for selected cases.

Why do I need a Corneal Transplantation?

Corneal Transplantation can help in restoring or improving the vision, in case you have a damaged cornea. It is helpful in healing:

  • Degeneration of innermost layer of cornea (Fuchs dystrophy)
  • Keratoconus
  • Bulging cornea
  • Thinning of the cornea
  • Scarring, clouding or swelling in the cornea
  • A corneal ulcer

How is Corneal Transplant Done?

In most cases a corneal transplant is done under anaesthesia, that would prevent pain and movement of the eye muscles. The surgery is done using a microscope. Your doctor/surgeon would remove a piece of your cornea and replace it with a new cornea, cut and fitted to your size, it will be sewn using an ultra-fine thread which will be removed later.

The surgery generally takes about an hour or two, you may spend some time in the recovery room to let the anaesthesia wear-off completely.

What to Expect?

Most patients are able to get their vision restored after a corneal transplant, though the result depends on your surgery as well as the extent of damage to your eye. There is a risk of cornea rejection, however, it can be managed with medications.

Corneal disorders and diseases are one of most common cause of blindness all over the world. If you or anyone you know has symptoms that are concerning, consult your doctor immediately.
