Normally the corneas are
gradually curved. Keratoconus
occurs when the cornea thins
and becomes more cone-shaped.
It can lead to a
range of vision problems.
Mild symptoms can be managed with glasses or contact lenses – rigid contact lenses are the most effective type for correcting the effects of keratoconus. Regular trips to your optician will aid early diagnosis. In more severe cases, a medical procedure may be required, which your doctor will be able to discuss with you in more detail.

Keratoconus occurs when the cornea thins and becomes more cone-shaped.
The cornea is the clear layer at the front of the eye. It is held in place by tiny collagen fibres. If these become weak, the cornea will bulge outward to give a cone-shaped appearance.
There are several potential causes of keratoconus, including genetics,
the environment and your endocrine system.
