Transcript of Astigmatism

By Adriana Giunta & Emily Devine Astigmatism What is Astigmatism? Astigmatism is an eye condition in which vision is blurred due to the failure of the optics of the eye to focus a point object into a sharp focused image on the retina. This is be due to an irregular shape of the cornea or eye lens. The two types of astigmatism are regular and irregular. Irregular astigmatism is often caused by a scratch on the cornea. It cannot be fixed by glasses, but can be fixed by contact lenses. Regular astigmatism occurring from the cornea can be corrected by contact lenses. This regular shape improves the regular astigmatism in the eye. What Causes It? Astigmatism is caused by an eye that is not completely round. Astigmatism occurs in nearly everybody to some degree. For vision problems due to astigmatism, glasses, contact lenses, and even vision correction procedures are all possible treatment options. But the exact cause is not known. How Serious Is It? How Badly Does It Effect Someone's Eyesight? Astigmatism is not serious and is very treatable. In the worst cases of astigmatism, a person might get headaches from the eye strain of distorted vision. Through glasses, lenses or surgery, this eye strain and blurry vision can be corrected. Astigmatism causes Blurred vision. ‘Ghosting’ or images that are doubled are the most common symptoms of astigmatism. These types of vision problems occur at all distances. Fatigue, eye strain and frequent headaches are other symptoms that may be a sign of astigmatism. Is There any Treatment or Cure? Astigmatic is often treated with glasses, contact lenses or refractive surgery (eye surgery used to improve the shape of the eye). This can include various methods of surgical remodeling of the cornea or cataract surgery. Successful eye surgery can reduce or cure the astigmatism.
