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. Check the statements below that apply to you and share this list with your doctor:
- I need to drive, but there is too much glare from the sun or headlights.
- 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 do not see well enough to do things I like to do (for example, read, watch TV, sew, hike, play cards, go out with friends).
- I am afraid I will bump into something or fall.
- Because of my cataract, I am not as independent as I would like to be.
- My glasses do not help me see well enough.
- My eyesight bothers me a lot.
You may also have other specific problems that you want to discuss with your eye doctor.
What Should I know About Surgery?
Your doctor will discuss the options with you before choosing the best kind of cataract removal and lens replacement for you. He or she will also explain how to prepare for surgery and how to take care of yourself after it is over.
Most people do not need to stay overnight in a hospital to have cataract surgery. You may go to an outpatient center or hospital, have your cataract removed, and leave when your doctor says you are fit to leave. However, you will need a friend or family member to take you home. You also will need someone to stay with you for at least a day to help you follow your doctor’s instructions.
It takes a few months for an eye to heal after cataract surgery. Your eye doctor should check your progress and make sure you have the care you need until your eye recovers fully.
Removing the Lens
There are three types of surgery to remove lenses that have a cataract:
- Extracapsular surgery. The eye surgeon removes the lens, leaving behind the back half of the capsule (the outer covering of the lens).
- Phacoemulsification (pronounced FAY-co-ee-mul-sih-fih-CAY-shun). In this type of extracapsular surgery, the surgeon softens the lens with sound waves and removes it through a needle. The back half of the lens capsule is left behind.
- Intracapsular surgery. The surgeon removes the entire lens, including the capsule. This method is rarely used.
Replacing the Lens
A person who has cataract surgery usually gets an artificial lens at the same time. A plastic disc, called an intraocular lens, is placed in the lens capsule inside the eye. Other choices are contact lenses and cataract glasses. Your doctor will help you to decide which choice is best for you.
A change in your glasses, stronger bifocals, or the use of magnifying lenses may help improve your vision and be treatment enough. The way to surgically treat a cataract is to remove all or part of the lens and replace it with an artificial lens.
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.Tags: cataracts, cataract treatment, Lens, vision, United States
A cataract is a cloudy area in the lens of the eye.
A normal lens is clear. It lets light pass to the back of the eye. A cataract blocks some of the light. As a cataract develops, it becomes harder for a person to see.
Cataract is a normal part of aging. About half of Americans ages 65 to 74 have cataract. About 70 percent of those age 75 and over have this condition.
Most people with cataract have a cataract in both eyes. However, one eye may be worse than the other because each cataract develops at a different rate.
Some people with cataract don’t even know it. Their cataract may be small, or the changes in their vision may not bother them very much. Other people who have cataract cannot see well enough to do the things they need or want to do.
What are the symptoms of a cataract?
This information can help you decide what to do if you have a cataract. Talk about it with your eye doctor so you can make the choices that are right for you.
Signs of cataract:
- Cloudy, fuzzy, foggy, or filmy vision.
- Changes in the way you see colors.
- Problems driving at night because headlights seem too bright.
- Problems with glare from lamps or the sun.
- Frequent changes in your eyeglass prescription.
- Double vision.
- Better near vision for awhile only in farsighted people.
These symptoms also can be signs of other eye problems.
See your eye doctor to find out what you have and how it can be treated.
A regular eye exam is all that is needed to find a cataract. Your eye doctor will ask you to read a letter chart to see how sharp your sight is. You probably will get eye drops to enlarge your pupils (the round black centers of your eyes). This helps the doctor to see the inside of your eyes. The doctor will use a bright light to see whether your lenses are clear and to check for other problems in the back of your eyes.
Other eye tests may also be used occasionally to show how poorly you see with cataract or how well you might see after surgery:
- Glare test
- Contrast sensitivity test
- Potential vision test
- Specular photographic microscopy
Only a few people need these tests.
