What is astigmatism?
Astigmatism is a common eye condition that causes blurred, distorted, or impaired vision. In many cases, astigmatism occurs in combination with other refractive errors like nearsightedness (myopia), or farsightedness (hyperopia) and is easily treatable.
What causes astigmatism?
In a person with regular vision, the eye’s cornea and lens have a circular shape and can focus light onto the eye’s retina. When the cornea is elongated (or football shaped), light focuses on more than one point on the retina, causing blurry and distorted vision.
How is astigmatism treated?
Thanks to advances in technology, astigmatism can be treated in a number of ways to match your exact eye condition and lifestyle. Together, you and your eye doctor can decide if glasses, contacts, or surgery will be your best option.
Astigmatic Keratotomy (AK)
AK is an outpatient surgical procedure that reshapes the cornea to reduce or eliminate astigmatism. During the 5-minute procedure, a surgeon will make microscopic incisions in the cornea. Most patients can return to their normal activities within a day or two of having AK performed.
Acrysof Toric ICL
Patients with astigmatism who also suffer from cataracts now have the option to solve both conditions in one procedure. Cataracts surgery involves removing the eye’s natural clouded lens (the cataract) and replacing it with a synthetic lens or IOL (Intraocular Lens). Until recently, patients with astigmatism were unable to select an IOL that would correct for astigmatism and in most instances were required to wear corrective lenses after surgery. Now, the advanced technology of an AcrySof Toric IOL can correct for astigmatism and may reduce or eliminate the need for glasses or contacts. The AcrySof Toric® has a unique design that makes it possible to also significantly improve distance vision.
The goal of any refractive surgical procedure is to reduce dependence on corrective lenses. However, we cannot guarantee perfect vision.
