What is a Cataract?

Normal vs. Cataract Vision

A cataract is a progressive clouding of the eye's natural lens that interferes with light passing through to the retina. Over 50% of people over 60 (and some younger) have cataracts. Cataracts worsen over time and vision changes are like looking through a waterfall or wax paper. Reading can become more difficult and driving dangerous. Some people experience bothersome glares, halos around lights, and/or double vision. There is no treatment to reverse or prevent cataracts. To achieve clear vision, the cataract must be removed.

Cataract Surgery Step-by-Step

Cataract surgery is performed on an out-patient basis, with local or "eye-drop" anesthesia, and takes only a few minutes.

1. A small incision is made in the side of the cornea. 2. An ultrasonic probe (phacoemulsifier) is used to break up and remove the cloudy lens.
3. An artificial intra-ocular lens is inserted. 4. The lens is in place and the incision heals without stitches.

Recovery

Many cataract patients report improvement in their vision immediately, and most patients return to their normal routines within a day or two.
