What is a Cataract?

The lens in the eye can become cloudy and hard, a condition known as a cataract.  Cataracts can develop from normal aging, from an eye injury, or from certain medications such as steroids. Cataracts may cause blurred vision, dulled vision, sensitivity to light and glare, and/or ghosting of images. If the cataract changes vision so much that it interferes with your daily life, the cataract may need to be removed. Surgery is the only way to remove a cataract. During the surgery a surgeon removes the clouded natural lens and replaces it with an artificial lens. The artificial lens is called an intraocular lens or IOL.

IOL Options

How do you know which lens to choose?

Your doctor will help you decide on the type of IOL that will replace your cloudy lens. The goal of cataract surgery is to correct the decreased vision that was caused by the cataract, and to help you achieve your best possible vision for your daily activities.


Nearsightedness or Myopia means that you are able to see close up and that images far away are blurry. Farsightedness or Hyperopia means that you are able to see far away images clearly and up close images are blurry.
