Corneal Transplantation Surgery
Effective Options For Your Visual Health
What is Corneal Transplantation?
Corneal transplantation or keratoplasty is also known as corneal grafting. It is an operation designed to correct blindness resulting from corneal disease. It involves removal of the damaged or diseased cornea which is replaced by donated healthy corneal tissue (the graft) either in its entirety (penetrating keratoplasty) or in part (lamellar keratoplasty). The graft is taken from a recently deceased individual with no known diseases or other factors that may affect the viability of the donated corneal tissue or the health of the recipient.
In corneal transplantation surgery only the corneal tissue (and not the whole eye) donated by one person is transplanted into the diseased eye of another person who has been blinded by a corneal scar or disease.
Am I The Candidate For Corneal Transplant Surgery?
Patients with conditions leading to corneal blindness benefit from corneal transplantation. Some of these indications are…
- Corneal scarring from past infections, injuries or surgeries.
- Keratoconus and other conditions with thin and distorted cornea.
- Swelling in cornea due to hereditary weakness of corneal cells or due to surgery
- Complications from LASIK, chemical injuries.
What is Corneal Transplantation Surgery?
Corneal transplantation surgery involves surgical removal of the unhealthy cornea (either total or partial) and replacing it with a healthy, transparent donor cornea (complete or partial). A cornea transplant surgery is also known as keratoplasty.
Our surgeons discuss possible treatment options with the patient and decide on the choice of the corneal transplant procedure, depending on the disease entity.

Frequently Asked Questions
Some mistakenly believe that a blue-eyed person’s eyes cannot be used for transplantation in a brown-eyed person. The only tissue used in the transplant is the cornea, which has nothing to do with the colored part of the eye.
Many people are under the false impression that one good eyeball is transplanted for another eyeball which is diseased. Since the eye is connected to the brain by the optic nerve, which is a part of the central nervous system, the eye is not and cannot be transplanted.
Corneal transplantation restores vision only in eyes that have been partially blinded by corneal disease. If a person is blinded by glaucoma, a detached retina, or degenerative change and the retina has been damaged or destroyed, nothing can restore lost sight. In favorable subjects the rate of success of corneal transplantation may be as high as 90%, with good final visual acuity with glasses. In unfavorable subjects, the rate of success may be around 10 to 20%. Each patient is evaluated individually before definite results can be predicted.
The most important factors in determining the final results are:
- Basic corneal disease (some types of corneal disease respond better to corneal transplantation than others).
- State of the donor’s cornea.
- Surgical technique and skill.
- Healing ability of the recipient cornea.
- Sensitivity reactions between donor and recipient cornea may lead to transplant rejection.
- Presence of concurrent eye diseases like glaucoma, retinal diseases reduce the chances of good visual outcome The advantages of lamellar keratoplasty (newer techniques) are better visual outcome, quicker rehabilitation and lower rates of transplant rejection.
If the operation is successful and the graft is accepted by the recipient eye, it remains clear and the vision starts to improve with time (provided the lens and the retina behind the cloudy cornea are normal). Healing after corneal transplant is a slow process and takes up to 1 year before all sutures can be removed. The vision fluctuates over the first 6 months and glasses are prescribed after healing is complete. Additional surgery like LASIK or PRK can be done if the patient wants to get rid of glasses.
