Keratoconus

Vision changes - keratoconus

Keratoconus is an eye disease that affects the structure of the cornea. The cornea is the clear tissue that covers the front of the eye.

With this condition, the shape of the cornea slowly changes shape from round to a cone shape. It also gets thinner and the eye bulges out. This causes vision problems. In most people, these changes continue to get worse.

Cornea

The cornea is the crystal clear portion of the surface of the eye that lets light enter. The cornea is well supplied with nerve endings which is why some people can never get used to wearing contacts.
