Does a Cataract Mean a Tumor?


------------------------------------------------------------------------------

QUESTION:  When a person develops a cataract in their eye, does this mean that
they have grown a tumor that is blocking their vision?  How does this tumor
spread to the other eye?  I suppose that these conditions can easily be
destroyed using the new laser guns, but I can't find a doctor to do it for me.
Can you help?

------------------------------------------------------------------------------

ANSWER:  I suppose the best way I can help you is to explain the nature of a
cataract and the operation that removes it, for you have a great many
misconceptions about the condition.  However, your ideas are expressed in many
other letters so you are not alone in your ideas.  A cataract is not a tumor,
in fact not a growth of any kind.  The lens of the eye, normally as
transparent as clear glass, begins to grow cloudy, fogging over and preventing
the light from the images in our world, to pass through the lens and strike
the back of the eye (retina) where the light can be transformed into
electrical impulses that pass on to the brain.  And cataracts do not spread
from one eye to the next, since they do not result from a process of infection
either.  Rather both eyes may develop the same condition at about the same
time, usually gradually over a long period of time.  When too much of the lens
becomes affected, and vision is diminished partially or completely, the opaque
lens may be removed, but lasers are not used in this type of surgery.  Once
the cloudy lens is removed, sight is restored, and the use of special glasses
can bring vision back to near normal.  Contact lenses may sometimes be used as
well.  In some cases the surgeon will position a new, artificial lens
(intraocular lens or IOL) to replace the damaged one that was removed.  Your
eye doctor can help you chose the right combination of surgical procedure and
corrective lenses to suit your personal style of living, and restore to you
the precious gift of sight.  Over 90% of people who go through these
procedures regain useful vision.
