What is Keratoconus?
Keratoconus is a progressive eye disease that causes thinning of the dome-shaped cornea. As the cornea thins, it slowly starts bulging outward into a cone shape. The change in shape damages the cornea’s ability to refract light. This results in blurry or distorted vision, nearsightedness, and increased sensitivity to glare. This often affects your night vision while driving.
Keratoconus can occur in one or both eyes, and the exact cause is unknown. It usually becomes noticeable in the late teenage years. Early on, eyeglasses and soft contact lenses may help to correct vision problems. Eye surgery is often needed as the disease progresses and vision gets worse.
