At some point, your vision may get bad enough that you feel unsafe or unable to do your daily tasks. Then doctors will do surgery to remove your cataract. During surgery, doctors replace your eye's natural lens with an artificial (man-made) one. Surgery takes about 30 minutes. You can go home the same day. Cataract surgery can be done on a person of any age and is generally safe even for people with illnesses such as heart disease and diabetes.
You’ll use eye drops to prevent infection and help your eye heal
You'll have some follow-up visits with your doctor
Your vision will improve within a few weeks after surgery, but you may still need glasses for reading or driving at night
Rarely you might have an infection, bleeding, high pressure, or swelling in your eye
Doctors will treat any problem that may develop

To help prevent cataracts:
Protect your eyes from the sun by wearing glasses or sunglasses with a UV (ultraviolet) coating

Eat foods with vitamins C and A and with nutrients called carotenoids (found in carrots, sweet potatoes, and dark green leafy vegetables such as spinach and kale)
Don't smoke or drink too much alcohol
