Keratoconus means "conical or cone-shaped cornea". It is a condition where the cornea (the clear window on the front of the eye) becomes stretched and thin and begins to bulge into a cone-like shape. The cornea is the major focusing surface of the eye, so keratoconus causes blurred and distorted vision. In keratoconus the normal physical properties of the cornea are altered, and this causes refractive error, usually short-sightedness (myopia) and irregular high astigmatism. It usually affects both eyes, but sometimes one eye may be badly affected whilst the other eye shows very little sign of the condition.
How is it treated?
The initial stage of treatment is to prescribe rigid gas-permeable contact lenses to improve vision. Patients have regular check-ups to ensure that the contact lenses remain suitable.
Further treatment is available to stem the progression of keratoconus. This includes:
A number of different grafts are available depending on the specific diagnosis. These include:
- Corneal Cross-linking
- Intracorneal Ring Segments (ICRS)
- Corneal Graft Surgery
The choice of treatment would be prescribed based on the results from the tests that would be performed during your consultation.
