Corneal transplant, also known as corneal grafting, is a surgical procedure where the damaged or diseased part of a cornea is replaced with corneal tissue from the deceased donor. A cornea is a transparent, dome-shaped membrane that covers the eye surface and is responsible for most of the focusing of light entering in the eyes.
A Corneal transplant surgery becomes necessary when the vision deteriorates to the point where the sight can no longer be improved sufficiently with glasses or contact lenses and medical treatment may no longer be able to relieve any pain. A corneal transplantation can correct vision loss , reduce pain and improve the appearance of a diseased or damaged cornea.
Corneal transplants are the most common transplant surgeries done today and has a success rate of over 90 percent. This procedure has come as a new ray of hope for visually impaired people who can be cured by corneal grafting.
The success rate of corneal transplant surgery as a remedy for corneal blindness is fairly high! A graft can only be considered if the person's vision has deteriorated to the extent that it is impairing his or her ability to lead a normal life.
