This eye condition affects the cornea at the front of the eye. It usually starts in the teenage years or 20’s and worsens, becoming stable by the age of 40.

It causes changes in the shape, strength and thickness of the cornea. The cornea bulges outwards and develops a cone shape. This affects the vision, and you may be more sensitive to light.

The condition is usually managed by specialised contact lenses, and there are some treatments available.
