What is a cataract?

A cataract is a clouding of the eye's lens. The lens is located behind the iris and the pupil and is made of water and protein. The lens works similar to a camera lens, focusing light onto the retina at back of the eye. Another function of the lens is focus, making things clear, both near and far.

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 may grow larger, making it difficult to see.

What are some symptoms of cataracts?

• Blurred vision
• Light may seem too bright and cause more glare
• Colors may appear less bright

How is a cataract treated?

When a cataract is diagnosed, you may be able to improve your vision temporarily with the following; new glasses, bifocals, magnification, better lighting or other visual aids.

You should strongly consider surgery when your cataracts have progressed enough to seriously worsen your vision and interfere with daily activities. Despite any fear you may have about surgery to remove a cataract, it is actually a simple procedure with minimal pain and works in regaining your vision. In fact, it is the most frequently performed surgery in the United States.
