Cornea transplants may be required if functional vision cannot be achieved by medications or special contact lenses. Conditions for cornea transplants include: Keratoconus, a steep curving of the cornea, cornea failure following other eye surgery, hereditary conditions, scarring after infections, injury or rejection after cornea transplant.
Your cornea may become hazy or damaged because of disease or injury. Corneal infections caused by inadequately cleaned contact lenses can lead to permanent corneal damage if not treated promptly. Trauma to the eye can likewise permanently injure the cornea, as can certain progressive diseases, such as keratoconus.
