Astigmatism is a fairly common condition that causes blurred or unclear vision, streaks through lights, or double vision. It is not a disease, but rather the result of an irregular shape to the front surface of the eye. In astigmatism, there is a deviation of the natural spherical curvature of the eye. Simply put, the front of the eye is shaped more like a football instead of a basketball.
Astigmatism can accompany other vision conditions such as nearsightedness and farsightedness, all of which are referred to as “refractive errors” because they affect the eye’s ability to bend or “refract” light. An irregularly shaped cornea prevents light from focusing properly on the retina, causing objects at any distance to appear more blurry.
What are the symptoms of astigmatism?
Most people have some degree of astigmatism. Minor astigmatism may not affect a person’s vision at all. However, a more significant astigmatism results in distorted or blurred vision. Other symptoms include headaches, fatigue, excessing squinting, and eyestrain.
Eye Specialists of Indiana encourages yearly eye care exams with your family eye doctor to evaluate and monitor visual changes, as well as maintain the best long-term eye health.
How is astigmatism treated?
Astigmatism is generally treated with either eye glasses or contact lenses. Another method for reducing astigmatism is by changing the shape of the cornea through refractive eye surgery, like SMILE or LASIK.
If you are a candidate for cataract surgery, you may elect to have your astigmatism treated. Dr. Paul Walton and Dr. Bill Shultz can correct the shape of your cornea with precise surgical techniques or with an advanced technology lens implant to help reduce astigmatism. Sight Options are available at Eye Specialists of Indiana for each patient to review and elect based on their visual lifestyle needs and candidacy. The doctors and staff will help you understand your choices and make the best decision for you.
