Since the 1970s, advances in microsurgical techniques and eye banking procedures have led to widespread acceptance of this procedure. Sometimes your body may reject the donated cornea even after years of cornea surgery. Therefore, it is essential to detect early signs of rejection. The first signs of a corneal rejection include pain, redness, and watering of the operated eyes. Consult your eye hospital immediately if you experience these symptoms.

Anshu A (1), Price MO, Price FW Jr. The cornea is the transparent front part of the eye that if damaged, can be replaced by a corneal transplant (keratoplasty) using healthy cornea tissue from a donor. A penetrating keratoplastyinvolves replacing all the damaged cornea. It is necessary to prevent the transplanted material (graft) from being rejected. Specific risk factors for corneal allograft rejection have been well recognized for decades and are generally used to place potential transplant recipients into low- or high-risk categories to decide whether or not to proceed with transplantation and which immunosuppressive regimen to employ. 8 In “high-risk” corneal transplant recipients, rejection episodes occur in 30%–60% of grafts Transplant rejection occurs when transplanted tissue is rejected by the recipient's immune system, which destroys the transplanted tissue.Transplant rejection can be lessened by determining the molecular similitude between donor and recipient and by use of immunosuppressant drugs after transplant.
Without blood vessels the body's immune system is less likely to recognise and reject the “foreign” graft.

Many corneal grafts in recipients with corneal neovascularization or the sequelae of ocular inflammation undergo irreversible rejection, despite topical immunosuppression with glucocorticosteroids. Sensitization to cornea-derived alloantigen proceeds by both direct and indirect Rejection. Corneal transplants are an effective treatment, but with all transplants there is a risk of rejection. This occurs when your body’s immune system recognises the transplanted tissue as foreign tissue and starts to attack it. Corneal Transplant Surgery is a surgical procedure performed to replace your cornea entirely or partially with healthy corneal tissue from a donor. The first signs of a corneal rejection include pain, redness, and watering of the operated eyes.
The cornea -- the most frequently transplanted solid tissue -- has a first-time transplantation success rate of about 90 percent. But second corneal transplants undergo a rejection rate three
