You will need to have each done separately. Sometimes, a cataract should be removed even if it doesn't bother you. For example, if it prevents examination or treatment of another eye problem such as age-related macular degeneration or diabetic retinopathy, a cataract should be treated. If you've chosen to have surgery, it's helpful to know more about it. This section describes the types of cataract surgery, lens substitutes, and what you can expect before and after surgery.
Cataract removal is one of the most common operations performed in the U.S. today.
It is also one of the safest and most effective. More than 90 percent of people who have cataract surgery have better vision afterward. However, even with the best results, your vision may not be as good as before the cataract. The lens is enclosed in a capsule, an outer covering that holds it in place. Your doctor opens the front of the capsule and removes the lens, leaving the back of the capsule in place.
