Cataract surgery: Does the artificial lens deteriorate over time?

My doctor has recommended cataract surgery. How long does the artificial lens last? Will it have to be replaced at some point? Also, will my vision deteriorate over time or stay the same?

Answer

In cataract surgery, the ophthalmologist removes the clouded lens from your eye and replaces it with a clear, artificial lens. This lens is very durable and should last for the rest of your life.

Your vision after cataract surgery generally doesn't deteriorate over time. However, sometimes the lens capsule that holds the implant becomes cloudy. In such cases, the cloudy capsule can easily be treated with a laser to make it clear again.

Most people will require glasses after cataract surgery — either for close-up work, distance or both. If you currently wear glasses, your prescription will likely require a correction for close-up work after surgery.
