What is Astigmatism?
Astigmatism is an eye condition with blurred vision as its main symptom. The front surface of the eye (cornea) of a person with astigmatism is not curved properly. The curve is irregular, usually one half is flatter than the other half, similar to the shape of a football. When light rays enter the eye, they do not focus correctly on the retina, resulting in a blurred image. Astigmatism may, though less common, also be caused by an irregularly shaped lens or cataract. In this case, once the cataract is removed, the astigmatism is also gone with it. Astigmatism can be treated with LenSx limbal relaxing incisions, which reshape the eye to make it rounder. It can also be treated with a Toric Lens Implant, LASIK, Glasses and Contact Lens.
