Causes of Astigmatism
Astigmatism is usually caused by an irregularly shaped cornea or lens. This can be caused by genetics, or it can be acquired. In some cases, astigmatism is caused by an eye injury or eye surgery.
Diagnosis of Astigmatism
Astigmatism is typically diagnosed during a comprehensive eye exam. During the exam, your eye doctor will check your vision and will use a special device called a keratometer to measure the curvature of your cornea.
Treatment of Astigmatism
Astigmatism can be corrected with eyeglasses, contact lenses, or refractive surgery. In some cases, eyeglasses or contact lenses may be the best option for correcting astigmatism. In other cases, refractive surgery may be the best option. Your eye doctor will be able to recommend the best option for you based on your individual needs and lifestyle.
