Astigmatism

Astigmatism: (Distorted Vision)

In an eye with astigmatism, the front of the cornea is not equally curved; it is slightly oval in shape, like a football. Light rays entering the eye bend unequally, resulting in a distorted image. Astigmatism usually occurs in conjunction with myopia or hyperopia. Symptoms alone can be difficult to detect, but those affected may notice a subtle difficulty focusing on printed words. We can identify this condition during a vision exam. Eyeglasses, contact lenses and refractive surgery can effectively treat astigmatism.

To treat astigmatism, the cornea can be made more spherical with the LASIK procedure. By changing the pattern of the beam, tissue is removed in one direction more than the other.

Cataracts and Astigmatism

If you have Astigmatism and Cataracts, ask our doctors about surgical options to correct astigmatism at the time of Cataract Surgery.

One method is to safely place partial thickness incisions in the cornea at certain locations to change the shape of the cornea and make it more rounded or spherical, these are call Limbal Relaxing Incisions.

The second method is to correct Astigmatic error with a slightly oval shaped Cataract Lens Implant which can counteract the oval shaped cornea and effectively cancel out the astigmatism, these are called Toric Impants.

Talk to one of our skilled surgeons about which procedure (or a combination) is right for you.
