Laser - eye surgery

The first procedure, with which the cornea with a laser beam was modelled, was, short, the photorefractive keratectomy, PRK. Here the surface of the cornea is cleared away, by it one evaporates. The laser beam is applied directly to the surface of the cornea.

In those last years became LASIK developed. With LASIK first a lobate cornea is prepared, as the cornea is easily begun to cut. Afterwards the laser models an internal layer of the cornea and not interferes on its surface. After the modeling, the rag is pressed of its place and serves in such a way as a kind of natural federation. The cornea heals faster, and the patients have fewer complaints than with the PRK.
LASEK , a combination of the procedures, places LASIK and PRK . Similarly as with LASIK and PRK with the excimer laser cornea fabric is cleared away, in order to achieve a higher visual acuity of the patient. For this the operating surgeon the layer of the cornea must - which epithelium - first to prepare. This happens with the help of a special instrument, the cornea trepan, which produces for epithelium cover moose.
By a new method mentioned custom cornea reaches the laser correcture a higher rank quality. An individual adjustment of the cornea is reached by this method.
