Keratoconus

What is Keratoconus?

We see through the cornea, which is the clear, central part of the front surface of the eye. The cornea normally has a round shape, like a ball. Sometimes, however, the structure of the cornea is just not strong enough to hold this round shape. The normal pressure inside the eye makes the cornea bulge outward like a cone, and this condition is called keratoconus.

Why Do People Get Keratoconus?

Often the cause of keratoconus is unknown. Some studies have found that keratoconus runs in families, and that it happens more often in people with certain medical conditions. But most often, there is no eye injury or disease that explains why the eye starts to change.

Keratoconus usually begins in the teenage years, but it can also start in childhood or up to about age 30. The changes in the shape of the cornea occur slowly, usually over several years.

Someone with keratoconus will notice that vision slowly becomes distorted. The change can stop at any time, or it can continue for several years. In most people who have keratoconus, both eyes are eventually affected.

Symptoms of Keratoconus?

Symptoms, that may be caused by keratoconus are:

- Sudden change of vision in just one eye
- Double vision when looking with just one eye
- Objects both near and far look distorted, but not blurred. In other words, small details of the objects are clear, but the shapes or colors look wrong. Later, distant objects
  do become blurred.
- Bright lights look like they have halos around them.
