Information on keratoconus and corneal collagen cross linking

The clear window at the front of the eye, the cornea, is usually a round, even shape. Keratoconus (pronounced keh-rah- toe-cone-us) is when the cornea becomes thinner and bulges outwards in a cone shape. Keratoconus is a progressive condition and can get worse gradually over time. The speed of change and severity varies between affected people. For detailed information on keratoconus please click here.

Corneal collagen cross linking is recommended for patients who are at risk of significant progression (worsening) of keratoconus.  The aim of crosslinking is to stabilise the corneal shape (that is, to stop it getting any worse). For detailed information on corneal crosslinking please click here.
