Cataracts

 

Question: What is the eye condition called Cataracts?

 

Answer: A cataract* occurs when the normally clear lens within your eye becomes cloudy and opaque. Cataracts can vary from extremely small areas of cloudiness to large opaque areas that cause a noticeable loss of vision. This condition is most likely to occur in patients over 60, but occasionally can be found in younger patients including newborns. When cataracts form they usually develop in both eyes, but often at different rates.

 

Cataracts develop without eye pain or redness. Indications that a cataract may be forming include blurred or hazy vision, the appearance of spots in front of the eyes, or the feeling of having a film over the eyes. No one knows exactly what causes cataracts to form. It is known that a chemical change occurs within your eye that causes the lens to become cloudy. This chemical change could be brought on as a result of advancing age, heredity, eye injury or disease. Other risk factors are excessive exposure to the ultraviolet radiation in sunlight (UV rays), cigarette smoking and certain medications.

Currently, there is no proven method to prevent cataracts from forming. Wearing UV protective sunglasses can shield the eyes from harmful UV rays that can accelerate cataract formation. A diet rich in antioxidants, such as vitamins A, C, E, Zinc, Selenium and Magnesium are seemingly beneficial as well.

A comprehensive eye health examination done by your Optometrist can determine if cataracts are forming. In the early stages of this condition your Optometrist can prescribe new lenses for your glasses to help obtain the sharpest vision possible. In the advanced stage of this condition your Optometrist will refer you to an eye surgeon who may recommend surgical removal of the cataracts. This surgical procedure is at least 95 percent successful.

The Canadian Association of Optometrists recommends the following comprehensive eye health examination guidelines:

• Birth to 5 years: Immediately, if parents sense a problem, otherwise by age 3 and again prior to entering school.
• School age children 6-19 years: Annually or every 2 years.
• Over 19 years of age: Every 2 years or sooner if recommended by your Optometrist.
