What causes corneal disease and degeneration?
Infections, whether bacterial, fungal or viral are frequent causes of sever corneal damage ulceration. Abnormal steepening of the cornea (keratoconus), degeneration occasionally following cataract surgery (corneal edema or swelling), and some aging processes can also affect the clarity and the health of the cornea. Some disorders of the cornea are inherited and can lead to corneal clouding and the loss of sight.
