LASIK helps change the shape of the cornea with the use of
excimer laser. The knife that is used in the operation to remove a flap in the
cornea is called microkeratome. There are several techniques that are employed
to reshape the cornea. After the laser has reshaped the cornea, the flap is
repositioned over the treatment area by the surgeon.
There are several advantages to this procedure:
LASIK is considered as one of the greatest ophthalmologic breakthroughs in
recent times. Many eye surgeons believe that even the most complicated
refractive errors can be treated with the help of LASIK. This is a relatively
simple procedure that allows a patient to go home right away after the operation
and ensures a renewed vision within a week.
LASIK is an almost painless procedure with the use of anesthesia to the
eye and the cornea. A very small number of patients have complained of little
discomfort during surgery, much like a "scratchy feeling." After the effect of
anesthetic wears off, there is a varying degree of discomfort among the
patients. But even if there is any irritation, it is usually minor and does not
last beyond a few hours. However your eyes may be very sensitive to light for a
few days.
As LASIK is a relatively simple procedure, it can be performed at the clinic,
instead of at a hospital. Most laser treatments do not take more than 15 to 40
seconds, depending on the degree of correction required. Recovery time is also
minimal, and most patients are able to go back home after 30 minutes. Within 3
to 5 days following LASIK treatment, you will notice a dramatic improvement in
your vision.
LASIK treatment of your vision is more or less permanent. With age however some
degree of re-treatment may become necessary.
Thus LASIK is a safe way of correcting your vision. So take advantage of this
advancement in ophthalmology and start seeing the world like you once did with
your new vision.
