Laser
Vision Tests Before Surgery
If
you have decided that you want to have laser surgery to correct
your vision you will have to see if you are a goodcandidate for the
procedure. Not everyone is. To begin with find a reputable surgeon
and go see them. They will do an eye examination to see whether it
can be done and if so how much work is necessary to correct your
eye condition. They will also check to see if you have any type of
eyes diseases. If you have dry eye this must first be treated
before you are able to have the surgery. The tests that are done
will include everything from the most simple to the most complex.
First there will be the chart tests to see how good you can see.
Next there is the refraction test. This one is when the doctor puts
a phoropter on your face and chooses a series of different lens
until you can see clearly.
As well, to
double check your prescription the surgeon will use an aberrometer.
This is one of the machines that you lean into and it automatically
tells the doctor what your eyesight is. There are other tests that
are done including one to make sure you do not have glaucoma. The
next step in determining the degree of correction you will need
with the laser surgery is to take photographs of your eye. This
will be very much like mapping your cornea. This is essential to
the procedure. The final examination step will be when your doctor
discusses with you your overall health. They will want to know if
you are taking any medication. There are some medical
conditions that will prevent the surgeon from going any
further.
There are
certain eye problems that will prevent the surgeon from going any
further. These include keratoconus, conjunctivitis, advanced
glaucoma and cataracts. If you are pregnant the surgeon will
recommend you wait until after you have the baby. This is because
certain hormonal changes during pregnancy affect your vision and so
a concise report of how you see will not be obtainable at that
point. Most surgeons will not do laser surgery if you have
AIDS/HIV, diabetes type one or rheumatoid arthritis because these
things interfere with your healing ability.
