Keratoconus is a vision disorder that occurs when the normally round cornea (the front part of the eye) becomes thin and irregular (cone) shaped. This abnormal shape prevents the light entering the eye from being focused correctly on the retina and causes distortion of vision. This condition usually occurs in your twenty or thirties, resulting in a moderate to marked decrease in visual acuity.
With the proper treatment (glasses, contact lenses, or a corneal transplant), most people with keratoconus will enjoy good vision for the rest of their lives. Thanks to modern contact lenses and surgical techniques, it is rare for someone with keratoconus to be severely visually disabled.
Treatment can be as simple as treating underling causes such as allergies and asthma or a coorect glasses prescription correcting the astigmatism caused by keratoconus. If these treatments don’t work, the next level of tratment for keratocomus is rigid gas permeable contact lenses. Surgical techniques are the final treatment If the condition progresses to the point where contact lenses cannot be fit.
