Lasik (Laser In-situ Keratomileusis)
The word "Lasik" can be interpreted as: "modification of
shape inside the cornea by the application of laser radiation".
The classical Lasik
treatment was introduced to Switzerland in 1994 by Dr.
Aus der Au. As a laser pioneer, he had recognized early that this
revolutionary technique for the treatment of visual defects could offer
many persons the possibility of a life without glasses or contact lenses
in a safe uncomplicated and gentle way. Today, however, Dr. Aus der Au
relies mainly on a further development of the Lasik method, i.e. Femto
Lasik.
Lasik – the steps of the treatment
In classical Lasik too, the interior of the cornea is modified by laser
radiation according to the visual defect to be corrected. To access the
interior of the cornea, the lamella of cornea (flap) is prepared mechanically
with a surgical cutting device (microkeratome) and not with a laser, as
in the modern Femto-Lasik version. After the preparation of the flap,
the corneal bed is treated exactly as in the Femto-Lasik method with the
so-called Excimer laser to correct the
visual defect present. The corneal flap is set back in place and re-attaches
itself by suction, and the eye lid can be moved again without hindrance.
In the first 2 weeks, any physical effect on the eye should be avoided.
This is why you must avoid rubbing your eyes during this time. At night
you must wear an eye protection for one week and protective glasses during
the day. You will find more information on the details of the surgical
procedure under Operation.
Properties
of Lasik in comparison to other laser treatments
- The lamella of cornea is cut out with a mechanical cutting device (microkeratome)
- No wound formed at the surface of the cornea
- No or very limited pain
- No or only limited cicatrisation on the cornea
- Short recovery time
- Subsequent laser corrections are possible
Range
of possible corrections with the Lasik method
Depending on the thickness of the cornea, the Lasik method permits the
durable correction of visual defects of +4 diopters in case of hyperopia
and of ca. –8 diopters in case of myopia, in combination with an
astigmatism of up to 5 diopters.
