Astigmatism is an eye condition that affects vision. The cause of the distortion is an abnormally shaped cornea. The cornea should be spherical in shape, but in the case of astigmatism the cornea is in the shape of a football. Astigmatism may be hereditary and is often congenital. It may also result from eyelid pressure on the cornea. Glasses or contact lenses can correct vision problems arising from astigmatism. Some cases may be helped with refractive laser eye surgery.
