Cataract Surgery

In cataract surgery, the cloudy natural lens must be removed from the eye. After that, in most cases a permanent intraocular lens (IOL) implant replaces the natural lens to restore focusing power.

When to have cataract surgery often is a subjective decision, based on how well you are able to see during routine activities. You might be able to drive, watch television and work at a computer for quite a few years, even after you are first diagnosed with cataracts.

However, if you have cataracts, you may eventually start to notice "ghost" images and declining visual clarity, which can't be corrected withglasses or contacts. Colors may begin to look faded, too. If your functional vision is impaired significantly and it becomes difficult for you to perform your normal daily activities, it may be time for cataract surgery.
