Astigmatism is a common visual problem that results in blurry vision at all distances. The condition occurs when the cornea—the outer portion of your eye—is shaped like an oval rather than a circle. When the shape of the cornea is oval, the eye cannot properly focus light, resulting in blurry vision.

The cause of astigmatism is unknown, but Eyesight Associates offers several treatment options. If you have astigmatism, learn more about your vision condition below. Then, schedule an appointment at Eyesight Associates to begin your journey toward clearer vision.

Types of Astigmatism

The most common form of astigmatism is corneal, meaning the shape of the cornea is distorted. Astigmatism can also be lenticular, which happens when the lens of your eye is not shaped properly. The lens sits inside your eye behind the cornea, and it is also responsible for focusing light.

Sometimes, corneal astigmatism is the result of a condition called keratoconus. This vision disorder occurs when there is a progressive thinning of the cornea, causing it to bulge outward and form a rounded cone shape.

Treatments from Eyesight Associates

The vision experts at Eyesight Associates have many years of experience treating astigmatism. Often, your vision can be corrected with the use of special eyeglasses and contacts designed for an oval-shaped cornea. In many instances, astigmatism can be corrected through surgery.

Laser Vision Correction

Eyesight Associates performs PRK laser vision correction for patients with astigmatism. This procedure uses an excimer laser to reshape the cornea, making it more round. This treatment option is best for people with “regular astigmatism.” Unfortunately, those with “irregular astigmatism,” meaning the front of their eye does not have a smooth surface, are not candidates for surgery. To determine which type of astigmatism you have and if you are a candidate for laser vision correction, talk to your Eyesight Associates doctor.
