Keratoconus is a progressive thinning and steeping of the cornea due to a weakening of collagen fibers in the cornea. Normally, the collagen fibers work to keep the dome shape of the cornea, however, in keratoconus these fibers have weakened and a bulging occurs. This bulging generally progresses to an event that can cause a patient to have a change in prescription, including an increase in nearsightedness (myopia) and astigmatism.
Keratoconus usually starts in the teenage years, however, effects of the thinning of the cornea can go unnoticed for years. The change in the shape of the cornea can occur very quickly or it may occur over several years. Common visual symptoms experienced are blurred vision, glare and halos at night, and the streaking of lights. These patients usually do not achieve 20/20 vision through glasses but may achieve better vision through contact lenses.
Dr. Alamo-Leon will evaluate these patients and recommend options of either glasses, contact lenses, or a referral for an extensive evaluation by a corneal ophthalmologist.
