A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over age 40 and is the principal cause of blindness in the world.
In fact, there are more cases of cataracts worldwide than there are of glaucoma, macular degeneration and diabetic retinopathy combined, according to Prevent Blindness America (PBA).
Cataracts typically develop slowly and can affect one or both eyes. Symptoms may include faded colors, blurry vision, halos around light, trouble with bright lights, and trouble seeing at night.
Cataract surgery is one of the most common and successful surgical procedures performed worldwide. The surgery involves removing the clouded lens and replacing it with a clear artificial lens implant called an intraocular lens (IOL).
Modern cataract surgery is typically performed using a technique called phacoemulsification, which uses ultrasound energy to break up the cloudy lens into small pieces that are then gently removed from the eye.
The procedure is usually done under local anesthesia and takes about 15-20 minutes. Most patients experience significant improvement in their vision within 24 hours after surgery.
