A clouding or loss of transparency of the lens in the eye as a result of tissue breakdown and protein clumping. There are many causes of cataracts, including aging, cortisone medication, trauma, diabetes, and other diseases. Cataracts affect most people who live into an old age. Symptoms include double or blurred vision and sensitivity to light and glare. A physician can diagnose cataracts by examining the eyes with a viewing instrument. Sunglasses can help to prevent cataracts. 


  1. Clouded, blurred or dim vision
  2. Increasing difficulty with vision at night
  3. Sensitivity to light and glare
  4. Seeing "halos" around lights
  5. Frequent changes in eyeglass or contact lens prescription
  6. Fading or yellowing of colors
  7. Double vision in a single eye


If you are planning to have surgery to remove a cataract, you now have an additional option... An implantable lens that makes it possible to treat the cataract and correct the corneal astigmatism at the same time. Your eye doctor will recommend the option that is best for you. The operation itself entails making a tiny incision in the eye. Through this incision, the surgeon inserts an instrument about the size of a pen tip. This instrument breaks the cloudy lens into pieces and removes them from the eye. Once the cataract is removed, a cataract replacement lens is inserted through the same tiny incision and set into position to replace the natural lens.

The good news is that you've encountered cataracts at a time when intraocular lens technology has taken great leaps of progress. Traditionally, the replacement lens used for cataract surgery was a monofocal IOL. This lens restored good functional distance vision, but people still needed to continue wearing distance and reading glasses.

Today, you also have the option of the AcrySof ReSTOR multifocal lens, which can improve vision in a full range of distances, from near, intermediate and far. This lens provides QUALITY distance vision, independent of eye glasses and contact lenses

Another great option is the AcrySof Toric IOL. The unique design of this lens makes it possible to reduce or eliminate corneal astigmatism and significantly improve distance vision. Patients who desire this lens will most likely be independent of glasses to see far and will need glasses only to read or do close work.
