The lens of your eye is behind the iris and pupil. It works
a lot like the lens of a camera, focusing light onto the retina, where images
are recorded. The lens is also what allows us to see things up close and far
Normally, the lens of your eye is clear. When you have a
cataract, proteins in the lens begin to clump together and cause cloudy vision.
Often, cataracts begin to develop when people are in their 40s or 50s. But
cataracts often aren’t very noticeable until they’ve grown. Generally, they
begin to cause vision problems when you’re in your 60s or older.

Surgery is the treatment for cataracts
When a cataract reaches the point where it’s affecting your

eye and replaces it with a new one. The success rate for the surgery is 95
percent among people who have healthy retinas.
Cataract surgery is almost always done on an outpatient
basis. You’ll receive a local anesthetic to numb your eye, which makes the
Some people feel a bit squeamish when they think about
having eye surgery, especially when they know they’ll be awake during the
procedure. But people who have the operation are usually pleasantly surprise.
We asked “Barbara,” who had the surgery two years ago when
she was 70, to describe her experience. “What did it feel like to have cataract
surgery?” we asked. “Nothing!” she said. There’s no pain. I was talking to my
doctor the whole time. I felt kind of dreamy, and then it was over and I felt
Barbara says the surgery helped her vision, and, she says,
“I have glaucoma, and my doctor thinks the cataract surgery helped lower the
glaucoma pressure in my eye.”
Barbara suggests having the surgery for anyone who’s
suffering from cloudy vision and whose doctor has recommended the procedure.
“It’s no big deal at all,” she says. “It’s painless.”
