What is astigmatism and how is it treated?

Vision problems such as nearsightedness and farsightedness are often talked about, but astigmatism is another refractive vision problem that affects many people. These are all problems that occur because the eye does not focus light properly. But what is astigmatism, and how is it treated.

What is astigmatism?
Astigmatism is a refractive eye error which is caused by the abnormal curvature of the cornea.  As a result of this irregularity, the rays that enter the eye are not able to focus onto a single point at the back of the eyes, as happens when the cornea has its natural shape. With astigmatism there are 2 points of focus, and this results in distorted or blurry vision.

How is it treated?
Astigmatism can be corrected with eyeglasses, contact lenses, or surgical options such as LASIK (laser-assisted in situ keratomileusis). LASIK eye surgery is beneficial for individuals with mild to moderate astigmatism.

LASIKis a vision correction procedure in which a thin flap is created in the cornea, and is folded away. An excimer laser is then used to reshape the cornea, after which the flap is repositioned. Reshaping the eye adjusts the focus of the eye, and improves vision.

PRK or photorefractive keratectomy is another surgical solution for astigmatism. PRK is a similar procedure to LASIK, but with PRK the entire thin outer layer of the cornea is removed.

Both LASIK and PRK are outpatient procedures that can be performed in just a few minutes.
