Cataracts often form slowly and cause no pain, redness, or tearing in the eye. Some stay small and don't change eyesight very much. If a cataract becomes large or thick, it usually can be removed by surgery. Most people have plenty of time to decide about cataract surgery. Talk to your doctor about your options.
Cataract surgery is very safe.
Most people do not need to stay overnight in a hospital after surgery. It usually takes a few months for the eye to heal after cataract surgery. Glaucoma results from too much fluid pressure inside the eye. It can lead to vision loss and blindness. The cause of glaucoma is unknown.
