Whether you need cataract surgery depends on how much of
a problem the cataract causes for daily activities like driving and reading.
Surgery is almost always by your choice (elective) and can be scheduled when it
is convenient. For people who decide to have surgery, the surgery usually
works very well.
Some people have to have surgery. Children are
sometimes born with cataracts that need to be removed. Other people may get
cataracts after an eye injury or as a result of eye disease or other health
problems. Cataracts from these causes may also need to be removed.
There is no proven
way to prevent cataracts. But there are some things you can do that may help
slow cataract growth. Don't smoke. Wear a hat or sunglasses when you are in
the sun. And avoid sunlamps and tanning booths. Eat healthy foods. And keep diabetes under control.
