Keratoconus is a condition of the eye in which the normally rounded cornea bulges outward into a cone shape. The cornea is the clear, central part of the front surface of the eye. It protects your eye and helps you focus for clear vision.

Symptoms and Causes

What are the symptoms of keratoconus?
-Gradually worsening vision in one or both eyes. (Generally, keratoconus affects both eyes.)

-Having double vision when you look out of just one eye.

-Seeing halos around bright lights.

-Being sensitive to light. (The term for this sensitivity is photophobia.)

-Having vision that gradually becomes distorted. With distorted vision, straight lines might look curvy or bent, and objects don’t have their correct shape.

What causes keratoconus?

The cause of keratoconus is largely unknown. Some studies have found that keratoconus runs in families, and that it happens more often in people who have certain medical conditions.
In most cases, you don’t have an eye injury or a disease that leads to keratoconus. People with keratoconus tend to rub their eyes a lot, which may cause the condition to develop more rapidly.
