LASIK is
the combination of a surgical incision (keratomileusis) and the laser
technique.
The incision technique in conjunction with the preciseness
of the laser provides for a good predictability and for a quick rehabilitation
period for even high refractive errors. LASIK has been developed from
PRK and has been used since the early 1990's.
The major advantage of LASIK over PRK is that the corneal
surface is not disrupted.
The result is that scarring after LASIK surgery is significantly decreased
compared to PRK and you will have no postoperative pain. The corneal
tissue is comparable to your skin: a large skin abrasion is much more
painful and will leave behind a bigger scar than a small incision. |

With LASIK, the stromal bed, rather than the outer surface of the corneal
tissue, is sculpted.
In order to allow access to the stromal bed of the cornea, a thin flap
of corneal tissue is created with a microkeratome and is turned back.
Alternatively, the flap can be cut using a femto second laser (Femto-LASIK). |
