Before you decide to take LASIK surgery, you should understand all the
facts that might affect you. Is LASIK surgery the right option for you?
LASIK surgery promises you to improve your vision permanently thus you
become independent of eye glasses or contact lenses, or at least lessen
your dependence upon them.
You are suggested to consult with an optometrist that specializes in
LASIK surgery. The doctor will conduct a number of tests to determine 
if
you are a good candidate for the surgery. Generally, laser eye surgery
corrects vision problems, such as Myopia (nearsightedness), where you
can see things that are near, but not objects that are far; Hyperopia
(farsightedness), where you see objects that are far, but not those 
that
are near; and Astigmatism, where irregularities in the cornea distort
images on the retina of the eye.
As part of the tests, the doctor will examine your eye health history. 
A
few things may be taken into consideration, such as whether you have 
had
a change in your eyewear prescription over the last year or so. If the
answer is yes, you may not be able to undertake lasik surgery due to 
the
fact that your eyes need to be stable for a period at least one year.
Other example is whether you have a history of particular diseases, 
such
as glaucoma, herpes, eye injuries or thin corneas. If this is the case
then the doctor possibly would not let you take lasik surgery.
After you pass the eye examination you may be given psychological
counselling to prepare you prior to the surgery. An important thing to
remember here is to let yourself relax and remain positive about the
outcome.
During the actual surgery, you will be seated in a reclined position.
The doctor will give you a numbing solution in the eye that is being
operated on. A microscope will be aimed right at the eye, which is made
constantly open using a special speculum.
The doctor will insert a ring to your eye with hard pressure to create 
a
suction effect on the cornea. He will then use a knife to cut the part
of the cornea that requires the reshaping. This procedure will cause a
blurry vision to your eye.
After the cornea has been cut the ring is removed, at this point, you
will be able to see, although this will come and go during the rest of
the LASIK surgery. There are two part of the operation where the laser
is introduced, two actually. The first laser is for your eye to focus
on; the second is the working laser.
The entire operation is made possible by the use of a smart computer.
The computer connects to the machine with the microscope. This computer
controls the amount of strength that is available in the laser. Prior 
to
the operation, the surgeon will have programmed how much tissue needs 
to
be removed from the cornea, based on the tests in the first visit. The
computer then, stops the laser when the exact amount of tissue has been
removed.
Your surgery is practically complete. There are a number of things you
should apply after the surgery. Even though you can technically come
back to normal daily life after a couple of days, you should be aware 
of
some restrictions to protect your eye over some period of time.
