Corneal transplantation, also known as corneal grafting, is a surgical procedure that replaces a damaged or diseased cornea with healthy tissue from a donor. The cornea is the clear front part of the eye that helps focus light. 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 into place. Recovery can take several months, and patients may need to use eye drops and attend follow-up appointments. Success rates are generally high, making it a common treatment for various corneal conditions.
