Cataract surgery is an operation to remove your eye’s lens when it is cloudy.
The purpose of your lens is to bend (refract) light rays that come into the eye to help you see. Your own lens should be clear, but with a cataract it is cloudy. Having a cataract can be like looking through a foggy or dusty car windshield. Things may look blurry, hazy or less colorful.
The only way to remove a cataract is with surgery. Your ophthalmologist will recommend removing a cataract when it keeps you from doing things you want or need to do.
During cataract surgery, your cloudy natural lens is removed and replaced with a clear artificial lens. That lens is called an intraocular lens (IOL). Your ophthalmologist will talk with you about IOLs and how they work.
Your ophthalmologist will measure your eye to set the proper focusing power for your IOL. Also, you will be asked about any medicines you take. You might be asked not to take some of these medicines before surgery.
You may be prescribed eyedrop medicines to start before surgery. These medicines help prevent infection and reduce swelling during and after surgery.
Your ophthalmologist may ask you not to eat any solid food at least 6 hours before your surgery.
Cataract removal surgery may be done in an outpatient surgery center or in a hospital. Here is what will happen:
cataract surgery, an ultrasound
instrument breaks up the center
of the cloudy lens and suctions
Like any surgery, cataract surgery carries risks of problems or complications. Here are some of those risks:
Your vision could become cloudy or blurry weeks, months or years after cataract surgery. This is not unusual. Your doctor might call this a “posterior capsular opacification (or PCO).” It's also called "secondary cataract" or "scar tissue." It's not like a scar you get on your skin. But because it happens after the eye has healed from cataract surgery, some people think of it as a scar. It happens when a membrane called the posterior capsule becomes cloudy. It might help to think of the posterior capsule as a transparent pocket. It holds your IOL in place. It also once held your eye’s natural lens (what became the cataract) in place. If you notice cloudy vision again, you might need to have a laser procedure. The laser creates an opening in the cloudy capsule and is called a posterior capsulotomy (or a YAG laser capsulotomy). This procedure helps restore clear vision.
Cataract surgery will not restore vision lost from other eye conditions such as macular degeneration, glaucoma, or diabetic retinopathy. Your ophthalmologist will talk with you about the risks and benefits of cataract surgery.
Cataract surgery costs are generally covered by Medicare if you are Medicare eligible. Private insurance usually covers cataract surgery as well.
Medicare will cover your costs if your vision tests at a certain level of acuity or clarity. Private insurance plans may have similar vision requirements. If your surgery is covered you may still have some costs. Special types of IOLs will cost more. Choosing to have cataract surgery before your vision has deteriorated enough will cost more.
In certain cases, it might be possible to get coverage before you meet the age or vision requirements. Talk with your ophthalmologist if you are considering having early cataract surgery.
What do you do if you don't have Medicare or private insurance coverage? You may still be able to reduce and manage the cost of cataract surgery. Ask about payment plans through your doctor's office. See if your employer offers flexible spending accounts that can help. Your ophthalmologist can help you learn more about costs of cataract surgery. Discuss your options for affording the procedure.
