Keratoconus occurs when your cornea thins and gradually bulges forward into the shape of a cone. Keratoconus usually develops in people ages 10 to 25 with symptoms occuring in late teens to late 20s. If you have a family history of keratoconus, you may have a higher chance of developing it. Some people with keratoconus may not experience symptoms until later in life. Some common symptoms include blurred and/or distorted vision, frequent changes in eyeglass prescriptions, problems with night vision, increased sensitivity to light, and difficulty with contact lens wear. Each eye can be affected differently and show symptoms at different periods in time. In the early stages of keratoconus, glasses or contact lenses can help to correct vision. If the disorder progresses, glasses may not be adequate and contact lenses may become more difficult or even impossible to wear. In advanced cases of keratoconus, there are surgical options such as corneal inserts or corneal transplantation. You may schedule a consultation with Dr. Frank Rosenbaum to discuss these possible options.
