Just because you have a cataract does not mean it must be removed immediately. Cataract surgery can almost always be put off until you are unhappy with the way you see. Your eye doctor will tell you whether you are one of a small number of people who must have surgery. For example, your doctor may need to see or treat an eye problem that is behind the cataract. Or surgery may be required because a cataract is so large that it could cause blindness.
Most people have plenty of time to decide about cataract surgery.
Your doctor cannot make your decision for you, but talking with your doctor can help you decide. Tell your doctor how your cataract affects your vision and your life. I do not see well enough to do my best at work. I do not see well enough to do the things I need to do at home. I am afraid I will bump into something or fall.
