Keratoconus is a weakening in the cornea. Normally the cornea is a dome shaped structure, but in keratoconus the cornea becomes cone shaped. The change in shape of the cornea distorts vision and makes images unclear. The condition is a slowly progressive and usually begins in the teenage years and progresses as one ages.


What causes Keratoconus?

The cornea is strengthened by collagen  in the cornea. In keratoconus there is a weakness in this collagen and the cornea bends foward. Keratoconus can run in familes. Family members of patients with keratoconus should have their eyes checked for keratoconus


How is Keratoconus diagnosed?

A ophthalmologist will perform specialized tests on your cornea in order to pick up the signs of keratoconus. Special photographs of your cornea are taken which are able to detect very early signs of keratoconus.


How is keratoconus treated?

In the early stages the vision is corrected with either spectacles or contact lenses. Cross linking of the cornea may be performed in order to stop the progressive worsening of vision. Cross linking strengthens the cornea by making the collagen bonds stronger. The procedure is performed as a out patient.

Advanced keratoconus is treated with a cornea transplant if vision is not adequately corrected with contact lenses. In certain cases ring segments may be implanted into the cornea in order to improve vision
