Cornea transplantation 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 restore sight for individuals suffering from conditions like keratoconus, corneal scarring, or Fuchs' dystrophy. 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 improve vision and quality of life.
