A cataract only needs to be removed when vision loss interferes with everyday activities, such as driving, reading, or watching TV. An eye care professional will determine the best option.
Sometimes, a cataract should be removed even if it does not interfere with vision. For example, a cataract should be removed if it prevents examination or treatment of another eye problem, such as age-related macular degeneration or diabetic retinopathy. If a patient has cataracts in both eyes that require surgery, the surgery will then be performed unilaterally (on each eye at a separate time).
