Cataracts

A Leading Cause of Vision Loss

More than 2.5 million Canadians have cataracts. They are painless, develop within the existing lenses in your eyes, and are usually detected during routine eye exams.

As you age, your lenses naturally harden and may also turn cloudy. A cloudy lens blocks light from reaching the retina and interferes with vision - the effect is similar to looking through a dirty car windshield. Cataracts may form in one or both eyes, at the same time or at different times.

Fortunately, cataracts can be removed and your vision can be restored. Surgery is usually recommended once a person feels their vision interferes with daily activities such as driving, reading or watching TV.

Cataract surgery is among the most highly perfected, safe and successful procedures in medicine – more than 95 per cent of patients have improved vision after surgery. It removes the cloudy lens and replaces it with an artificial one.
