A cataract refers to a cloudy lens in the eye. The intraocular lens is usually but not always clear in young people. As we age, the lens becomes yellow and cloudy resulting in:
- trouble distinguishing colours
- hazy vision
- increased sensitivity to glare
- most commonly the lens is replaced with an artificial one, and vision is restored
- there are over 1.5 million cataract surgeries in North America annually and over 95% of these are successful.
