CORNEA TRANSPLANT IN INDIA
Cornea Transplant in india
Replacement of a clouded cornea is the only means of restoring full vision. If the rest of the eye (including the retina and optic nerve) is normal , the cornea is replaceable through transplant surgeries. Corneal transplantation is one of the most successful organ transplant surgeries. The success of the procedure depends on the amount and type of damage the eye has sustained from disease or injury. However, it is important to remember that vision can be restored only to the extent that the other parts of the eye are normal.
Before Surgery in india
Once you and your ophthalmologist decide you need a corneal transplant, your name is put on a list at the local eye bank. Usually the wait for a donor cornea is short. Most eye banks are able to provide tissue for transplant surgery scheduled in advance for a specific day.
Before a donor cornea is released for transplant, the eye bank tests the human donor for the viruses that cause hepatitis and AIDS. The cornea is then carefully checked for visual clarity. Your ophthalmologist may request that you have a physical examination and other special tests prior to surgery. If you usually take medications, ask your ophthalmologist if you should continue them.
During Surgery in india
The operation is painless. Anesthesia is either local or general, depending on your age, medical condition, and eye disease. You will not see the surgery while it is happening, and you will not have to worry about keeping your eye open or closed.
After the anesthetic has taken effect, the eyelids are gently opened. Looking through a surgical microscope, your ophthalmologist will measure the eye to determine the size of the corneal transplant. The diseased or injured cornea is carefully removed from the eye. Any necessary additional work within the eye, such as removal of a cataract, is completed. Then the clear donor cornea is sewn into place. When the operation is over, the ophthalmologist will usually place a shield over the eye that has just received the transplanted cornea.
The Procedure in india
Only the central portion of the cornea is involved in transplantation .The surgeon excises an appropriate circular disc of the patient’s cornea and replaces it with a similarly sized disc of donor cornea, which is then sutured into place.
Tissue Availability in india
Corneas for transplant come from individuals who have donated their eyes for use after their death ,for the benefit of others. Donor corneal tissue can be used up to maximum of 4 days after the death of the donor depending on the modality of preservation. This includes screening for AIDS .Since Clear Vision Eye Centre is a recognised eye bank, we are able to network with other eye banks. This enables us to obtain quality tissue for our patients with minimum waiting period.
With a few exception, donor tissue up to age seventy years is usable. Factors such as sex, color of the iris, previous vision of the donor have no influence on the final outcome of the surgery. anyone wishing to be an eye donor should call the nearest Eye bank and pledge the same.
Risks in Corneal Transplant Surgery
As with any eye surgery, there is the possibility of loss of sight in the eye, loss of the entire eye or possible loss of life due to abnormal reactions to anesthesia. The risks are very small, but it is very important that you be aware that risks exist as with ant other surgical procedure.
Although cornea transplants are highly successful, unfortunately there can be no guarantees with corneal transplant surgery, just as there can be no guarantees with any other type of surgery. Some of the possible complications that could occur are infection, bleeding, glaucoma, a wound leak, poor wound healing, and failure or rejection of the transplant. If a transplant should fail, it does not mean blindness or loss of the eye. Rather a subsequent transplant may be performed with a good chance of success.
