Cataracts are a naturally occurring process in the human eye. In normal
development, we are born with a clear lens that focuses images onto the back of
the eye (the retina) like a lens focuses images for your camera. Over time,
ultraviolet light from the sun, by- products of the foods that we eat, and our
environment gradually cause the lens to become cloudier and cloudier. This can
begin to impact vision, usually after the age of 40, and become what we know as
a cataract.
Just having a cataract does not mean that any treatment is required.
Generally, treatment is indicated when the symptoms begin to interfere with your
daily activities and enjoyment of life. Common symptoms of cataracts include
increasing difficulty seeing to drive at night, disabling glare from oncoming car
headlights, and hazy vision in bright sunlight (glare). You may find that reading
and TV viewing are more and more of a struggle, even with updated eyeglasses.
The only treatment for cataracts is surgery. This involves using an
instrument through a microincision at the side of the eye to remove the cloudy
lens material, and replacing it with a tiny prosthetic lens implant, like replacing
the faulty lens of a camera. This usually takes less than 10 to 15 minutes,
requiring only local anesthesia, and can be done in an ambulatory care setting.
This means that you can be home and doing most of your normal activities within
a couple of hours of having your surgery performed. One eye is done one day, and
the other can usually be done anywhere from 2 to 4 weeks later, depending on a
patient’s preference and satisfactory recovery. Most patients are less dependent
on eyeglasses after cataract surgery, and many options are available to further
enhance the result. For example, surgery can be performed with the assistance of
laser (Femtosecond laser with Catalys or LensX technology), which can make
faster recovery possible and reduce astigmatism (irregularities in the shape of the
cornea, the clear front surface of the eye), for sharper vision. Advanced
technology lens implants (ATIOLS) like the Symfony and PanOptix lenses can give
patients the freedom to do more activities without the use of eyeglasses after
surgery. These special options are not covered by health insurance, so it is good
to begin to consider how you feel about eyeglass use before it is time to decide
upon cataract surgery, so that you may know about your possible choices and
invest wisely.
A comprehensive eye exam is the way to know if you have cataracts, so
make sure to schedule one at least annually. If your eye doctor says that you have
cataracts, don’t panic! Pay attention to your daily functioning, and consider
whether your the vision is interfering with the things you want and need to do the
most. If it is, there are outstanding treatment options available to help you
recover your sight, and continue to live your very best life
