Cataracts: Should I Have Surgery?

You may want to have a say in this decision, or you may simply want to follow your doctor's recommendation. Either way, this information will help you understand what your choices are so that you can talk to your doctor about them.

Cataracts: Should I Have Surgery?

Get the facts

Your options

  • Have cataract surgery.
  • Wait until poor eyesight caused by the cataract gets bad enough to bother you.

Key points to remember

  • Not all cataracts need to be removed. It depends on how much they bother you. Many people get along very well without surgery by wearing contact lenses or glasses.
  • Poor eyesight caused by cataracts happens slowly over time, so you probably don't need to rush into having surgery.
  • Most people who have cataract surgery see better after it. Serious problems from surgery aren't common.
  • Surgery removes the lens from your eye. The lens has to be replaced.
  • You may still need to wear glasses or contacts after surgery to see well.
FAQs

What is cataract surgery?

Cataracts are cloudy areas in the lens of your eye. Your lens is behind the coloured part of your eye (iris). Its job is to focus light onto the back of your eye. In some people, cataracts prevent light from reaching the back of the eye. This can cause vision problems.

Cataract surgery helps you see better. It replaces your natural lens, which has become cloudy, with a clear artificial one.

There are several types of cataract surgery. They include:

  • Phacoemulsification. This is the most common type. The doctor makes a small cut (incision) in your eye. A special ultrasound tool is used to break your cloudy lens apart. Then the small pieces of the lens are removed and replaced with an artificial lens. Most people do not need stitches because the incision is so small.
  • Extracapsular extraction. This uses a larger incision to remove the lens in one piece. It is replaced with an artificial lens. And the cut is stitched.
  • Femtosecond laser-assisted cataract surgery (FLACS). This uses laser technology and replaces the natural lens with an artificial lens.

How well does cataract surgery work?

Cataract surgery is successful for most adults. Surgery may also improve vision in infants who have cataracts.

Both phacoemulsification cataract surgery and femtosecond laser-assisted cataract surgery (FLACS) work about equally well for treating cataracts in adults. FLACS may not be completely covered by provincial health plans, but it may be a better option in some cases. For example, people who are going to have multifocal lenses placed may choose FLACS.

People who have surgery for cataracts usually have:

  • Improved vision.
  • Increased mobility and independence.
  • Relief from the fear of going blind.

What are the risks of cataract surgery?

Although the risk is low, surgery for cataracts does involve the risk of partial to total vision loss if the surgery is not successful or if there are complications. Some complications can be treated and vision loss reversed, but others cannot. Complications that may occur with cataract surgery include:

  • A torn lens covering (posterior capsule rupture).
  • Infection in the eye (endophthalmitis).
  • Swelling and fluid in the centre of the nerve layer (cystoid macular edema).
  • Swelling of the clear covering of the eye (corneal edema).
  • Bleeding in the front of the eye (hyphema).
  • Detachment of the nerve layer at the back of the eye (retinal detachment).

Complications that may occur some time after surgery include:

  • Problems with glare.
  • Clouding of the back portion of the lens covering (capsule) that remains after surgery. (Your doctor can easily treat this using a laser.)
  • Glaucoma.
  • Retinal detachment.
  • Astigmatism or strabismus.
  • Sagging of the upper eyelid (ptosis).

What are the risks of not having cataract surgery?

Usually, a cataract that isn't removed will slowly get worse and make your eyesight worse:

  • You may no longer be able to do your usual daily activities.
  • You may not be able to drive safely, especially at night.
  • You may be more likely to fall or hurt yourself.

The cataract may make it hard for your doctor to check for other eye problems, such as damage from diabetes.

When a cataract isn't treated until after it has become severe, the surgery may be harder to do. Also, you may be more likely to have problems after surgery or have a slower recovery than someone who had surgery for a less severe cataract.

Why might your doctor recommend cataract surgery?

Your doctor might recommend surgery if:

  • Poor eyesight is affecting your ability to do your job or take part in some leisure or social activities.
  • Surgery would help your doctor keep track of another eye problem, such as a problem with your retina.
  • You do not have glaucoma, diabetic retinopathy, or macular degeneration. Surgery may not improve eyesight in people who also have these eye problems.

When children have cataracts that cause vision problems, surgery is usually needed.

Have cataract surgeryHave cataract surgery
  • You will probably be awake during the surgery. You may feel pressure, but you shouldn't feel pain.
  • You will go home the same day.
  • Surgery works well to restore poor eyesight caused by cataracts.
  • Cataract surgery also improves eyesight for people who are nearsighted, are farsighted, or have astigmatism.
  • Your vision may be cloudy right after surgery. This will go away as your eye heals.
  • You may need laser surgery a few months or years later if your vision clouds up again.
  • Serious problems are not common but include:
    • A torn lens covering (posterior capsule rupture).
    • Infection in the eye (endophthalmitis).
    • Swelling and fluid in the centre of the nerve layer (cystoid macular edema).
    • Swelling of the clear covering of the eye (corneal edema).
    • Bleeding in the front of the eye (hyphema).
    • Detachment of the nerve layer at the back of the eye (retinal detachment).
  • You may still need glasses or contact lenses after surgery.
Wait and seeWait and see
  • You will decide when the cataract is affecting your vision and your life enough to have surgery.
  • You avoid the risks of surgery.
  • Your eyesight will continue to slowly get worse.
  • You may have a slightly higher risk of problems from surgery if you wait to have surgery until your cataract is severe.

Personal stories about cataract surgery

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

My left eye is so clouded that I feel like I'm looking through tinted plastic wrap. I'm a little nervous about the surgery, but I need to have good eyesight to read, play cards, and do other things like that. I will talk to my doctor and get more information about what to expect, then maybe I won't be so nervous.

Betty, age 72

I didn't even know that I had a cataract until my eye doctor told me about it during my last eye exam. I suppose my eyesight has changed a little bit, but it has happened so slowly that I haven't noticed it much. So long as I am still able to pass my driver's test and see well enough to do what I need to do, I don't plan to have surgery.

Bob, age 69

I have known about my cataract for a long time. Only recently has it started to bother me. It is very hard for me to drive at night, and I attend a lot of meetings in the evenings. Most people I know have had a good experience with cataract surgery. So I feel confident that the surgery is right for me and will help me see better at night.

Harold, age 67

I am very nervous about any surgery on my eyes. I know that cataract surgery is very safe, but it is still surgery on my eye, and the thought of blindness scares me. So far I am able to manage fine, and my eyesight is only affected a little bit. I am going to put off having surgery for as long as I can.

Marie, age 55
