What is Lasik Eye Surgery? How does it works?
LASIK eye surgery is
also known as Laser-assisted in Situ Keratomileusis. It is a
laser procedure designed to use a laser underneath a corneal
flap (in situ) to reshape the cornea (keratomileusis), so that
it changes the focal point of the eye. Ideally, the focal point
is changed so that it focuses perfectly on the retina, just like
a normal eye. Lasik eye surgery is a type of refractive surgery
used to treat common vision problems such as astigmatism,
nearsightedness, and farsightedness.
The Lasik eye surgery takes just a few minutes per eye.
Step
: Create ultra-thin flap on the surface of cornea
Your eye will be immobilized so that it can not move during
the procedure.
The new technology of Intra-laser Lasik that 80% of clinics have
adopted is LASIK flaps cut with a laser. It mean a safer surgery
as the results are more accurate, so fewer enhancements
needed, and the eye is left stronger. Then a flap is created in the
cornea, and is gently lifted up.

The standard technology use an instrument called a keratome, It is attached
to a suction ring, which allows a very precise incision. The
keratome unctions like a carpenter's plane,
seperating a very thin layer off of the front of the cornea. Then a flap is
created in the cornea, and is gently lifted up.
Step
: The cornea is reshaped for improved vision
By folding this flap of tissue back, the surgeon is able to
use an excimer laser to remove tiny pieces of the corneal tissue
until the cornea is shaped just right.
Step
: The flap is laid back into place, and immediately begins healing
After the treatment is completed, the flap is replaced and
allowed to dry into position. Very little healing is involved,
since the flap seals itself into position very quickly.
