Risks

A cataract is a clouding of the lens in your eye. It affects your vision. Cataracts are very common in older adults. By age 80, more than half of world population either have a cataract or have had cataract surgery. A cataract can occur in either or both eyes. It usually develops slowly and painlessly, and can eventually cause blurry vision and glare. Some people say it feels as if they are looking through a foggy or dirty window.

Cataract surgery is usually performed to improve vision. In some cases, it may be done to treat other problems associated with cataracts, such as pain or inflammation. It is a relatively safe and effective procedure. Complications are rare, but can include infection, bleeding, and retinal detachment.

If you have cataracts, your doctor will likely recommend surgery when your vision starts to interfere with your daily activities. Surgery is also an option if you have other health problems that make it difficult to care for your eyes.
