After the age of 50 most people will eventually be diagnosed with cataracts. Cataracts are when the natural crystalline lens of the eyes become clouded, causing vision impairment that can not be corrected by glasses or contact lenses. While commonly an age-related condition, occasionally there are infants born with a congenital cataract, and it’s possible for young people to develop a cataract related to trauma, injury or infection.

Cataracts are one of the leading causes of visual impairment and the leading cause of blindness worldwide. As of 2010 they were responsible for 51% of world blindness and as life expectancy continues to grow, so does the incidence of cataracts. The condition can be cured by surgical removal of the cataract, which is one of the most common surgeries performed in the United States and Canada.

Cataract surgery involves removing the clouded natural crystalline lens of the eye and replacing it with a clear intraocular lens (IOL). It is typically an outpatient procedure which does not require an overnight stay. Cataract surgery is one of the safest and most effective surgeries performed in North America today, having a 90% success rate (patient has improved vision, between 20/20 and 20/40 following the procedure).

The majority of patients will still need eyeglasses at least sometimes following the surgery so once your eyes have healed your doctor will fit you for a prescription. Secondary cataract can occur months or years after the initial cataract surgery. This is when an opacity develops behind the IOL and can mimic cataract symptoms. Regular checkups with your optometrist can detect this, and arrangements for a simpler laser treatment instead of surgery can resolve this problem.
