Cornea Conditions

About Corneal Conditions

Pterygium

A pterygium is a fleshy growth that extends from the inner corner of the eye towards the cornea. A pterygium is caused by exposure to sun, wind and dust and therefore tends to occur in people who spend a lot of time outdoors. The best way to guard against a pterygium is to wear UV filtering sunglasses and avoid exposure to sun, wind and dust.   

Keratoconus

Keratoconus is an uncommon, progressive condition where the cornea becomes weak causing it to lose its regular shape and bulge forward into a conical shape. The result is an increase in astigmatism which causes distortion of the vision. In the early stages, Keratoconus can be treated with glasses, contact lenses and Collagen Cross-linking. Corneal transplant is sometime required at the late disease.  

Corneal Transplant

A corneal transplant is the surgical removal of damaged cornea and replacing it with healthy donor tissue. It is a complex surgery and involves either a full-thickness or partial-thickness transplant.
