What Is A Cataract?

A cataract is the clouding of the lens in the eye. The lens is responsible for focusing light rays on the retina, which helps you see. When your lens becomes clouded with a cataract, you may notice that images seem dull or blurred, have increased difficulty seeing at night, or have light sensitivity. If your doctor sees a cataract in your eyes, he or she will monitor them until they are ready to be removed.


What Are the Causes of Cataracts?

Most cataracts are caused simply from aging. As we age, proteins in the natural lens break down.  As they break down, they deposit on the lens and cause the clouding that you see in your vision.  Although age-related cataracts are the most common type, there are other circumstances under which a cataract will develop. Other causes include the following:

  •    Congenital cataracts that are present at birth
  •    Traumatic injury to the eye
  •     Radiation treatments to the eye
  •     UV exposure from sunlight


What Is the Treatment for Cataracts?

The only treatment for cataracts is to have them removed by surgery. Cataract surgery will generally be recommended when they have grown to the point that they are affecting your vision and your ability to perform daily activities such as reading.

During cataract surgery, the eye’s natural cloudy lens is removed by an ultrasonic probe and replaced with an intraocular lens (IOL). Since being approved by the FDA in 1981, IOLs have offered an efficient alternative for cataract patients. Before the use of IOLs, cataract patients had to wear very thick eyeglasses or special contact lenses in order to see once the natural lenses were removed. Following cataract surgery, many patients now need only reading glasses to read and can see clearly in the distance.
