Corneal Cross-Linking

Keratoconus is a condition of the Cornea which causes the shape of the Cornea to change from a regular and spherical shape to a more conical shape. Collagen fibres within the cornea usually provide structure and strength to the cornea. In Keratoconus they are abnormal and cause the structure of the cornea to be weakened.  This can cause significant changes to vision, causing symptoms such as blurring of vision and bright lights appearing to be streaked.

NQ Eye Specialists now offer Corneal Collagen Cross-linking. This procedure is used to slow down or halt the progression of Keratoconus.

The procedure is performed under a topical anaesthetic. Firstly, the outer layer of the cornea is removed.  After this, Vitamin B2 drops are applied to the Cornea and the Cornea is then exposed to Ultra Violet light. This process causes a chemical reaction, resulting in an increased number of bonds between collagen fibres resulting in a strengthened Cornea.
