LASIK
( Laser In Situ Keratomileusis ) is a proven procedure, performed
successfully for more than 10 years all over the world. With LASIK,
the surface of the cornea is reshaped by means of laser light in
order to adjust the refraction angle of incoming light so that the
focus is as close as possible to the point of best vision on the
retina.
Preliminary Examination
After the decision to proceed with LASIK treatment,
you will receive a series of preliminary examinations by an ophthalmologist,
who measures the dioptric power of the eye and the shape of the
surface of the cornea.
Preparation
The LASIK treatment is then performed, based
upon the data gathered during the preliminary examinations. Anaesthetic
drops will be placed in your eyes to numb them. Then subsequent
procedure is thus completely painless. During the procedure, a special
instrument holds the eye open. The surgeon uses a high-precision
surgical instrument known as a microkeratome to create a small corneal
flap by making an incision in the outer layer of the cornea, with
no damage to surrounding tissue. The device is then removed and
the surgeon proceeds by pulling the corneal flap back.
LASIK Procedure
The actual laser treatment can now begin.
It takes only a few seconds and in most cases, the entire procedure
is completed within less than one minute. In myopia eyes the centre
of the cornea is flattened, while in hyperopic eyes, the laser is
used to remove corneal tissue in order to increase the angle at
the edge of the cornea. Fast reflex eye movements are thereby tracked
by means of an infrared sensor system so that each laser pulse reaches
the targeted point. Once the laser surgery is completed the corneal
flap is returned to its original position.
After a short recovery period, you will be able
to see again properly and you will be ready to go home. Your surgeon
may also prescribe certain medications to reduce swelling and any
other discomfort. You might have to wear an eye patch for a short
time to keep your eye free of infection and prevent inadvertent
rubbing of the eye during the night. The healing process is completed
after a few weeks.
