Surgery is the only way to remove a cataract. The surgery works well and helps people see better. But surgery may not be needed or can be delayed for months or years.
Many people with cataracts get along very well with the help of eyeglasses, contact lenses, and other vision aids. Keep your glasses or contacts prescription up to date. Make sure you have plenty of lighting in your home.
Whether you need 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). It can be scheduled when it's convenient.
Some people must have surgery. These people include children who are born with cataracts that need to be removed and people who get cataracts after an eye injury or as a result of eye disease or other health problems.
