Have Astigmatism? Here's what that means.
Many patients come in concerned when they are told they have astigmatism. They think astigmatism is a terrible eye disease to be dreaded. In fact, astigmatism is a very common vision disorder.
What is Astigmatism?
Astigmatism is an uneven or irregular shape of your cornea, the front surface of your eye, or your lens, the part of your eye that focuses light onto your retina.
Normally, the cornea and lens are curved equally in all directions, allowing light rays to focus sharply at a single point on the retina. In an eye with astigmatism, light is focused in multiple points in the eye either in front or behind the retina. This can create blurred or distorted vision at near or far. Astigmatism can also cause eyestrain or headaches. In many patients, the amount of astigmatism may be so mild, it may cause no symptoms at all.
What can we do for astigmatism?
Astigmatism can range in severity and in many cases, astigmatism does not need any treatment at all. When correction is needed, different treatments include eyeglasses, contact lenses, and LASIK surgery.
LASIK surgery is a safe and effective treatment option for many patients to eliminate your need for eyeglasses or contact lenses. LASIK works by altering the curvature of the cornea. By re-shaping the surface of the cornea, astigmatism’s prescription error is corrected by creating a more spherical cornea. This allows light rays to properly enter the cornea through the back of the eye and focus a clear image on the retina.
