Cataracts

A cataract is a common condition that causes a clouding of the eye’s natural lens, and affects millions of people each year, including more than half of all Americans over the age of 65. Cloudiness develops as a result of a buildup of protein in the lens

Cataracts cause a progressive, painless loss of vision. The lens clouds naturally as we age, causing people over the age of 65 to see a gradual reduction of vision. However, cataracts are not considered part of the natural aging process and are a serious condition that requires prompt medical attention. The exact cause of cataracts is unknown, although it may be a result of injury, certain medications, illnesses (such as diabetes), prolonged exposure to ultraviolet light and smoking.

Diagnosing Cataracts

Your doctor may perform a series of tests in order to diagnose a cataract. A dilated eye exam will be performed to test the vision and to examine the condition of the lens and other parts of the eye. Your doctor may also perform tonometry, a procedure that measures the pressure in the eye.

Symptoms of Cataracts

Patients with cataracts often do not experience any symptoms when the condition first develops. Cataracts will continue to progress with no apparent pain, although patients may experience:

  • Blurred or hazy vision
  • Double vision
  • Poor vision in bright light
  • Seeing halos around lights
  • Poor vision at night
  • Yellowish tinged vision
  • Frequent changes in eyeglasses or contact lens prescription

Treatment of Cataracts

If visual impairment begins to interfere with your ability to read, work or do the things you enjoy, you may want to consider cataract surgery to restore your vision. Cataract surgery is the most commonly performed surgical procedure in the US, and can be performed quickly and easily with a success rate of over 90 percent and a minimal risk of complications.
