What is a cataract?
A
cataract is a clouding of the eye's naturally clear lens.
The lens focuses light rays on the retina at the back of the eye
to produce a sharp image of what we see. When the lens
becomes cloudy, the light rays cannot pass easily through it,
and the image becomes blurry.
Cataracts usually develop as part of
the normal aging process, but they can also result from eye injuries
and certain diseases or medications. Genetic factors may also
play a role in cataract development.
How can a cataract be treated?
There are no medications, eye drops, exercises or glasses that will
cause cataracts to disappear once they have formed. Surgery is the
only way to remove a cataract. When you are not able to see well
enough to do the things you like to do, cataract surgery should be
considered.
What will happen during surgery?
Surgery is usually done on an outpatient basis. When you arrive for
surgery, you will be given eye drops and perhaps a sedative to help
you relax. A local anesthetic will numb the eye. You may see light and
movement, but you will not be able to see the surgery while it is
happening. An eyelid holder is placed between your eyelids to prevent
you from blinking. |
