Keratoconus is a non-inflammatory condition in which cornea gradually thins and bulges outward into a shape of a cone. This process of reshaping cornea is known as corneal ectasia. Keratoconus is a bilateral ocular disorder and may affect each eye differently. Most people with keratoconus have only mild forms of the disease.
A cornea transplant may be needed when eyeglasses or contact lenses are not effective enough to restore the vision, or if medications do not help the painful swelling in eyes. A cornea transplant can be recommended by an eye specialist in many conditions which involve damaged cornea such as keratoconus.
