Corneal transplantation, also known as corneal grafting, is a surgical procedure that replaces a damaged or diseased cornea with a healthy one from a donor. The cornea is the clear front part of the eye that helps focus light, and its health is crucial for clear vision. This procedure can improve vision, reduce pain, and restore the appearance of the eye. The surgery typically involves removing the affected cornea and stitching the donor cornea in place. Recovery can take several months, and patients may need to use eye drops and attend follow-up appointments to ensure proper healing. Successful transplants can significantly enhance the quality of life for individuals with corneal issues.
