Astigmatism

When Vision Is Blurry at all Distances: Astigmatism

Do you have blurry or distorted vision when you’re trying to see an object that’s close to you or far away? Have you worn glasses or contacts for most of your life? Does your vision affect your enjoyment of everyday activities such as reading, working at a computer or watching a movie?

If so, you may have astigmatism. Astigmatism is a natural condition that occurs when the front surface of your eye, called the cornea, is shaped irregularly. A normal cornea is spherical, like a basketball. But a person with astigmatism has a cornea that is shaped more like a football. This causes blurry vision because light rays are distorted as they enter your eye and don’t focus properly.

Cataract Surgery Can Free You from Astigmatism

With today's advanced technology, your cataract surgery is also an opportunity to correct your astigmatism. That means you have the chance to not only gain your freedom from cataracts, but also to enjoy activities like driving and playing golf with less dependence on glasses.

During cataract surgery, your surgeon replaces the clouded lens in your eye with a new lens, called an intraocular lens (IOL). You can choose an IOL, such as the AcrySof® IQ Toric IOL, that can correct your astigmatism and greatly reduce — or even eliminate — your need for glasses or contact lenses for distance vision activities.
