Normally the cornea has a dome shape, held in place by a protein called collagen. When these fibers become weak, they cannot hold the cornea’s shape and the cornea becomes progressively more cone shaped. This condition is called keratoconus.
Keratoconus may run in families so if you have it and have children, it is good to have their eyes checked for this condition starting at age 10.
Changes in the shape of the cornea can happen quickly or may occur over several years. These changes can result in blurred vision, glare and halos at night. Severe keratoconus can lead to corneal tear or scarring.
Treatament for Keratoconus
Treatment usually starts with new eyeglasses. If eyeglasses don’t provide adequate vision, then rigid, gas permeable contact lenses may be recommended by your eye doctor.
