The sheer number of different eye corrective surgeries available
can be overwhelming at times. And since the matter concerns the
eyes, regarded by many as the most important of the five senses,
it becomes highly essential that you carry out a basic research
of the procedures available. This would certainly aid you in
selecting the most feasible and effective treatment. It is also
imperative that you have a grasp of how LASIK vision correction
works, since LASIK is the most prevalent type of eye surgery.
It is comforting to know that LASIK eye surgery has the most
advanced scientific technology at its disposal. It makes use of
high-precision equipment and dedicated technicians. For
instance, the surgeon employs the Excimer laser, which is an
amazingly precise ultraviolet chemical laser. As an evidence of
its precision, the Excimer laser is capable of removing 0.5% of
a human hair's width at a time.
At first, a thorough pre-operative examination is conducted, in
order to detect astigmatism and other irregularities in the
shape of the cornea. The patient is also advised to take a few
precautions approximately 7 to 10 days prior to the surgery.
LASIK eye surgery is performed with the patient awake and
functional, however, the ophthalmologist administers a mild
sedative and anesthetic eye drops. The surgeon performs the
surgery with the assistance of a dedicated technician who
controls the laser.
Basically, a flap is cut in the cornea using a blade (a
microkeratome) or a laser. The flap is lifted up to reveal the
middle section of the cornea. Then the Excimer laser is used to
make the desired incisions, in order to reshape the corneal
tissue. The cornea is carved in a finely controlled manner,
since the Excimer laser is a cool laser and does not produce
heat, which could otherwise damage the adjacent tissue. The flap
is then replaced to allow for natural binding.
Reshaping of the cornea in such a manner, corrects any
refractive error that the patient may have. LASIK procedure is
simple and the patient may go to work the very next day - sounds
like a very much doable treatment.
