Correcting Myopia and Astigmatism: What Are the Options?

Nearsightedness and astigmatism can be treated with a variety of vision correction procedures, such as LASIK or PRK. Eyeglasses are a common way to correct astigmatism, but contact lenses can also be used. There are several types of lenses available, including soft lenses, gas-permeable contact lenses, and hybrid lenses. Refractive surgery is another option for correcting astigmatism, as it changes the shape of the eyes.

When it comes to correcting astigmatism, the eye surgeon uses a laser beam to reshape the curves of the cornea. This helps to correct any refractive errors that may be present. If you think of a normal, healthy eye as being like a basketball, then astigmatism is like having an eye shaped like a soccer ball. To measure the amount of correction needed, an ophthalmologist will use a device that projects light into the eye and records any distortion in the return image.

Most astigmatism is regular astigmatism, which can be corrected with eyeglasses, contact lenses, or laser surgery. Irregular astigmatism is less common and is usually caused by scarring on the cornea due to eye surgery.
