A cataract is a cloudy or opaque area (an area you cannot see through) in the lens of the eye. The name cataract stems from an ancient conception of something cascading from the "brain of humors" and depositing itself in front of the lens. The retina is the eye's light-sensitive layer that sends signals to the brain that are interpreted as vision. Protein arranges itself to allow light rays to pass through and to focus the rays onto the retina. Other symptoms include faded colors, poor night vision, difficulty in reading, problem with bright light etc. Clouded vision can make it more difficult to read, drive a car especially at night or see the expression on a friend's face. In fact, they are the leading cause of visual loss among adults 55 and older. Eye injuries, certain medications, and diseases such as diabetes and alcoholism have also been known to cause cataracts. Sometimes, protein clumps together, clouding small areas of the lens and blocking some light from reaching the retina. The rate of cataract progression can be unpredictable. Some cataracts worsen significantly within a few weeks; others remain unchanged for many years.

The choices for treating cataracts in children depend on how likely the cataracts are to interfere with development of normal vision.

Cataract surgery consists of removing the lens of the eye and replacing it with an artificial lens. A cataract surgeon will discuss the options with the patient, and together they will decide which type of removal and lens replacement is best.

Sometimes, a cataract should be removed even if it doesn't cause problems with your vision. For example, a cataract should be removed if it prevents examination or treatment of another eye problem, such as age-related macular degeneration or diabetic retinopathy.
