Having laser surgery to correct a vision impairment has been an option for about 20 years. There are a range of procedures, such as Femto-LASIK, LASIK (laser in situ keratomileusis), LASEK (laser-assisted subepithelial keratectomy) and PRK (photorefractive keratectomy), as well as the minimally invasive ReLEx smile treatment method. The physician decides what method is best for each patient. Femto-LASIK is considered the most familiar and is the state-of-the-art procedure. A femtosecond laser is used to cut a thin flap from the cornea, which is then folded to the side. Then the excimer laser ablates the necessary tissue to correct the specific type of vision impairment, all within seconds. In the case of short-sightedness, the cornea is flatter, while it has a more angular shape in the case of far-sightedness. Once the procedure is complete, the flap is folded back into place. Patients can see again sharply shortly after the procedure. The most important requirement for an optimal procedure is that the physician must determine whether it is possible to perform laser surgery at all. The procedure can now be performed on an out-patient basis and usually only takes a few minutes.
