What the cornea does
The cornea is the clear dome at the front of the eye. It does most of the focusing. When it is scarred, infected or misshapen, vision becomes blurred or distorted.
Keratoconus and collagen cross-linking
In keratoconus the cornea thins and bulges into a cone. It usually starts in the teens or twenties, and glasses power changes often. Collagen cross-linking (CXL) uses riboflavin (vitamin B2) drops and a controlled ultraviolet light to strengthen the cornea. It aims to stop keratoconus getting worse. It does not remove the need for glasses or lenses.
- Early treatment protects more vision, so do not delay if your power keeps changing
- Special contact lenses can give clearer vision than glasses
- An implantable lens (ICL) may help some patients after the cornea is stable
Other cornea problems we treat
- Corneal infections and ulcers, which need urgent treatment
- Corneal scratches and injuries
- Corneal scars and swelling
See a doctor the same day for a painful red eye, especially if you wear contact lenses. A corneal infection can damage sight quickly.
