Expectations (prognosis)
For most people, cataract surgery has a low risk of complications. With implanted artificial lenses, most people no longer need corrective lenses for distance vision. Glasses are usually necessary for reading.
Complications
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.
In infants, amblyopia and decreased visual development may occur as a result of cataracts. Early diagnosis and treatment are essential.
Calling your health care provider
Call for an appointment with your health care provider if you have symptoms such as progressive worsening of vision, decreased night vision, or problems with glare.
Also call if you have a family history of congenital cataracts, or if your child has symptoms or signs suggesting a cataract.
Prevention
The best prevention involves controlling diseases that increase the risk of a cataract, and avoiding exposure to factors known to promote cataract formation.
Wearing sunglasses when you are outside during the day can reduce the amount of UV light your eyes are exposed to. Some sunglasses do not filter out the harmful UV. An optician should be able to tell you which sunglasses filter out the most UV. For patients who smoke cigarettes, quitting will decrease the risk of cataracts.
