Keratoconus is an eye disease that affects the cornea. The cornea is a thin clear tissue covering the front of the eye. A healthy cornea holds its round shape and helps us see. The cornea can become structurally weak and lose its shape. The cornea becomes cone-shaped causing poor vision. There is no known causes. Keratoconus may run in families and too much eye rubbing can cause this condition. Keratoconus is most prevalent in those who are near-sighted. There are no preventative measures for keratoconus but if you develop it there are many treatment options available.
Keratoconus usually develops in the teenage years and twenties, but it can begin even earlier, even during childhood. Most likely before the age of 30. It can progress for 10-20 years and then slow down considerably as the patient ages. Blurred vision and increased sensitivity to light are the first symptoms. At first, you may be able to wear soft contact lenses or eyeglasses to correct the nearsightedness and astigmatism. Eventually keratoconus may progress so much that glasses cannot correct your vision. Usually keratoconus can be corrected using rigid gas-permeable contact lens. Scleral contact lenses are a new type of lens that can improve comfort in cases of keratoconus. We specialize in fitting contact lenses for keratoconus.
In advanced cases, the cornea wears down at the very point of the cone shape. If this happens, you may need to undergo a corneal transplant. Recovery from this surgery can take a long time. The risk of the body rejecting a transplanted cornea is very low. Most patients will still need to wear contact lenses after the surgery.
Keratoconus is diagnosed by an eye exam. This examination is used to detect many eye diseases and problems, including corneal injuries, cataracts and macular degeneration. Regular eye examinations are a must. It is during these exams that our Optometrist has a chance to detect any conditions before they become a bigger problem. Once a year check-ups are instrumental in maintaining health vision over your lifetime. If you are having blurry vision please schedule an eye exam with us at Eye Mechanix.
