The only treatment for cataract is surgery to remove it. Surgery is done if you cannot perform normal activities, even with glasses.
If a cataract is not bothersome, then surgery is usually not necessary. However, some people may have additional eye problems, such as diabetic retinopathy, that cannot be treated without first having cataract surgery.
For some people, changing glasses, getting stronger bifocals, or using a magnifying lens is helpful enough.
For information on surgery, see: Cataract surgery
Vision may not improve to 20/20 after cataract surgery if other eye diseases, such as macular degeneration, are present. Ophthalmologists can usually, but not always, determine this in advance.
Early diagnosis and treatment are key to preventing permanent vision problems.
