CORNEA represents the very front surface of the eye or the outer surface of the eye. The cornea plays a major role in how you focus on images. In conjunction with your natural crystalline lens the cornea helps to provide required focusing power. Damage to the cornea may arise from various reasons such hereditary issues, chemical burns, blunt object trauma, viruses or bacteria. Conditions that may require a patient seek a cornea transplant involve, clouding of the cornea, keratoconus, fuchs dystrophy, irregular corneal surface tissue growths, or corneal swelling. If the cornea becomes weak or damaged serious problems may arise. Treating the cornea with medication is typically the first thing that the doctors will try. If your vision cannot be accurately corrected with medications, eyeglasses or contact lenses, a corneal transplant may be required.
Corneal Transplant, also known as a corneal graft, or as a penetrating keratoplasty, involves the removal of the central portion (called a button) of the diseased cornea and replacing it with a matched donor button of cornea. Corneal grafts are performed on patients with damaged or scarred corneas that prevent acceptable vision. This may be due to corneal scarring from disease or trauma. In this photo of a recent transplant, the fine V-shaped stitches can be seen clearly on the right side, though they extend all the way around the transplant.
