What is Lasik?
LASIK (Laser in situ Keratomileusis) surgery is known as
Refractive eye surgery that makes vision correction through the
use of a laser by reshaping the cornea and changing its focusing
power and more... This procedure can be used to correct myopia (nearsightedness),
hyperopia (farsightedness), and astigmatism (misshapen cornea).
How
it's done?
 Before
you undergo LASIK surgery. You must discontinue to used your lens
for 1-4 weeks prior to surgery to allow cornea return to original
shape. The operation day you go to meet ophthalmologist and LASIK
will be performed...
1) Anesthesia will be given to you to relieve pain or other discomfort.
2) The doctor use microkeratome to suction the ring that placed
on your eye and then cut the thin flap on its surface. This will
expose the layer called "stroma"
3) You will then be asked to focus on a fixed spot as your doctor
begins cutting , removing cornea by laser
4) You will be required to wear eye patch about 1 weeks and waiting
healing process of your eye completely.
Complications
During surgery, complications occur in less 0.5% of patients related
to the cutting or hinging of the flap . Other complications occurring
at less than a 1% rate include the development of an irregular astigmatism
due to scarring, healing, or beam problems, infection, or other
vision problems (halos around lights, blurry night vision) due to
decentration, surgery performed off the center of the pupil due
to surgeon error or the inability of the patient to focus on a fixed
point.
