Laser Eye Methods

Laser eye surgery is generally a surgical procedure that changes the overall refractive power of the eye. Thus conventional corrections such as glasses and contact lenses can be replaced. Short-sightedness, long-sightedness, and astigmatism up to certain dioptres can be corrected.

In the three treatment methods, an excimer laser remodels the cornea's surface structure, which corrects the refractive power of the eye. LASIK stands for laser in situ keratomileusis. In this procedure, a "corneal flap" is generated. After folding back the flap, the excimer laser painlessly models the shape of the cornea and corrects the defective vision of the eye. The flap is reattached and serves the eye as the body's own patch.

The PRK/Lasek method is a laser surface treatment of the cornea, in which no corneal incision is made. An alcoholic solution removes the uppermost cell layer, the so-called epithelium of the cornea, to process the subsequently exposed corneal bed with the laser. Since the tissue is removed directly on the cornea's surface, a superficial wound remains at the end of the operation. However, it heals within a few days.

It combines a method for precise corneal measurement (wavefront analysis) and Femto-LASIK. This combination makes it possible, based on the optical system's individual characteristics, to create a kind of "fingerprint" of the eye and further optimize the precision of the actual laser treatment.
