LASIK (Laser in Situ Keratomileusis) is a proven procedure,
performed successfully for more than 15 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.
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.
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. The subsequent
procedure is thus completely painless. During the procedure,
a special instrument holds the eye open with the other eye
protected by a shield.
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.
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 myopic 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.
