What is a cataract?
A cataract is a clouding of the lens of the eye. The lens is located behind the iris and the pupil and is made of water and protein. The lens works in a manner similar to a camera lens, focusing light onto the retina at the back of the eye. Another function of the lens is to focus both on near and far objects.
A cataract forms when some of the protein in the lens starts to clump together and cloud a small area of the lens. This happens as one ages and over time it may grow larger, making it difficult to see.
What are some symptoms of cataracts?
- Blurred vision

How is a cataract treated?
When a cataract is diagnosed, it is possible to temporarily improve your vision with the following: new glasses, bifocals, magnification, better lighting or other visual aids.
Cataract surgery is a painless procedure to restore vision and is among the most successful surgical procedures performed today. Surgery should be considered when your cataracts have progressed enough to impair your vision and interfere with daily activities. Cataract surgery is the most frequently performed surgery in the United States.
