Keratoconus

Keratoconus is a disease of the eye in which, slowly over time, the cornea becomes distorted.

Symptoms may not be obvious, as they are vision and eye health conditions themselves, such as light sensitivity, nearsightedness and astigmatism . It is not clear how keratoconus may develop, although heredity may play a role.

Since keratoconus is a progressive disease, appropriate treatment varies over time. Simple correction may suffice at an early stage, followed by rigid gas-permeable contact lenses, and eventually a cornea transplant.
