What is astigmatism?
Astigmatism is an eye disorder in which the cornea, a clear tissue covering the front of the eye, is abnormally curved. Astigmatism results in a vision problem, usually causing the vision to be out-of-focus. This common eye disorder usually occurs in combination with nearsightedness (myopia) or farsightedness (hyperopia). Astigmatism can be diagnosed during a standard eye examination and refraction test. No other special tests are usually required.
What are the symptoms of astigmatism?
The most common symptom is blurry vision. In most cases it will manifest as the inability to see fine detail when images are up close (such as reading) or far away.
How does the doctor treat astigmatism?
The eye doctor will usually prescribe eye glasses or contact lenses to correct the astigmatism. Some severe cases of astigmatism may be treated surgically. Uncorrected astigmatism in only one eye can lead to a problem called amblyopia.
