What Is a Cataract?

A cataract is a clouding of the eye’s natural lens. The lens functions much like the lens of a camera—normally clear, it focuses light onto the retina, which acts like the camera’s film to capture images. When the lens becomes cloudy, it is called a cataract.

Cataracts are a common part of aging. Most people begin to develop them in their late 50s or early 60s, though they can appear earlier. Cataracts do not cause pain, but they can lead to symptoms such as:

  • Blurred or cloudy vision

  • Glare or halos around lights, especially at night

  • Difficulty seeing while driving, particularly in low light

In the early stages, cataracts may cause little to no symptoms and often do not require treatment. As they progress, however, they can interfere with daily activities and quality of life.

Only a comprehensive eye exam can confirm whether a cataract is present and determine if treatment—such as cataract surgery—may be beneficial.

Can Cataracts Be Treated?

Yes. Cataracts are very treatable, and today’s options are highly effective. In the early stages, simply updating your glasses or contact lens prescription may improve your vision. However, once a cataract progresses to the point where new glasses no longer help, the only way to restore clear vision is through cataract surgery. There are no drops or medications that can reverse or cure a cataract.

Cataract surgery is one of the most common and successful procedures performed in the United States. During the surgery, the clouded natural lens is removed and replaced with a clear artificial lens implant.

How Is Cataract Surgery Performed?

At Tozer Lee Eye Center, Dr. Kevin Tozer and Dr. Michele Lee use the most advanced, minimally invasive techniques to perform cataract surgery.

The procedure is performed on an outpatient basis and typically takes about ten minutes. Most patients do not require stitches or an eye patch afterward and can resume normal daily activities the following day.

Your surgeon will review the risks and benefits of the procedure and discuss the available intraocular lens (IOL) options—some of which may significantly reduce your dependence on glasses.
