What is a cataract?
A cataract is a cloudiness of the eye’s natural lens, which lies between the front and back areas of the eye, directly behind the pupil.
Are cataracts found only in older people?
Most cataracts develop slowly over time and affect people over age 50. About half of the population has a cataract by age 65, and nearly everyone over 75 has at least one. But in rare cases, infants can have congenital cataracts. These usually are related to the mother having German measles, chickenpox, or another infectious disease during pregnancy, but sometimes they are inherited.
My doctor says I have a cataract, but he wants to wait a while before removing it. Why?
A cataract usually starts very small and practically unnoticeable but grows gradually larger and cloudier. Your doctor is probably waiting until the cataract interferes significantly with your vision and your lifestyle.
You need to continue to visit your eye doctor regularly so the cataract’s progress is monitored. Some cataracts never really reach the stage where they should be removed.
If your cataract is interfering with your vision to the point where it is unsafe to drive, or doing everyday tasks is difficult, then it’s time to discuss surgery with your doctor.
Is cataract surgery serious?
All surgery involves some risk, so yes, it is serious. However, cataract surgery is the most commonly performed type of surgery in the United States. Many cataract surgeons have several thousand procedures under their belt. In fact, Visual Health’s Dr. Coffman has performed more multi-focal lens cataract surgeries than anyone in the world.
How is a cataract removed?
A small incision is made in the front surface of the eye with a scalpel or a laser. A circular hole is then cut in the front of the thin membrane (anterior capsule) that encloses the eye’s natural lens. Typically the lens is then broken into smaller pieces with a laser or an ultrasonic device so it can be more easily removed from the eye.
Once the entire lens is removed, it is replaced with a clear implant called an intraocular lens (IOL) to restore vision. In most cases, the eye heals quickly after surgery without stitches.
Today, several steps in cataract surgery can be performed with a computer-controlled laser instead of hand-held instruments. Visual Health offers laser cataract surgery at our Jupiter Eye Surgery Center using our state-of-the-art Lensar technology.
What is a “secondary cataract”?
In a minority of cases (perhaps 20 to 30 percent), months or years after cataract surgery, the posterior portion of the lens capsule that is left inside the eye during surgery for safety reasons becomes hazy, causing vision to again become blurred.
This “secondary cataract” (also called posterior capsular opacification) usually can be easily treated with a less invasive follow-up procedure called a YAG laser capsulotomy. In most cases, this 15-minute procedure effectively restores clear vision.
My grandfather had cataract surgery years ago, and he had to wear thick glasses afterward. Is this still necessary?
Rarely does anyone have to wear thick, heavy eyeglasses after cataract surgery these days. Most modern cataract procedures involve the use of advanced technology and IOLs that often can correct your vision to 20/20 without glasses or contact lenses.
In fact, premium multifocal IOLs and accommodating IOLs can even eliminate your need for reading glasses after cataract surgery. During your pre-op exam, ask your cataract surgeon for more details about this exciting technology.
How much does cataract surgery cost?
Medicare and most health insurance plans will cover cataract surgery and ordinary intraocular lenses, but not the cost of premium IOLs, such as presbyopia-correcting IOLs that simultaneously correct vision at near, intermediate and distant ranges. These types of lenses can cost as much as $5,000 or more out-of-pocket for both eyes.
What are possible side effects of cataract surgery?
As with any surgery, pain, infection, swelling and bleeding are possible, but very few people experience serious cataract surgery complications. In most cases, complications or side effects from the procedure can be successfully managed with medication or a follow-up procedure.
To reduce your risk for problems after cataract surgery, be sure to follow the instructions your surgeon gives you and report any unusual symptoms immediately.
