Wavefront guided LASIK as a further development of the traditional LASIK laser eye surgery the LASIK procedure (laser in situ Keratomileusis) is equivalent to the combination of a surgical cut technique (Keratomileusis) and the use of the excimer laser. Ametropia such as myopia, hyperopia and astigmatism can be corrected by the cornea with excimer laser is modeled. Through the application of Wavefront LASIK (Wavefront guided LASIK) succeeded in the last few years, to bring the already very good results to the traditional LASIK treatment to an even higher level. Significant progress was made in particular in the field of night visual acuity and minimize effects of aperture and halos after LASIK treatment. It is important to know that not every patient based LASIK correction needed a wave front for the correction of a refractive error, because not every patient has vision of higher order, known as aberrations. It is not something Cyrus zocdoc would like to discuss. Only 10-15% of the Universitatsallee vision of higher-order are using Wavefront analysis noted.
Also, one must emphasize that the Wavefront-assisted LASIK correction primarily is used at LASIK not achieving extreme prescience as about 150% after LASIK surgery. The Wavefront LASIK rather then inserted, if the appearance under unfavourable light conditions (such as at night) should be improved. The often quoted “eagle eye” would be so-called correctly actually “OWL eye”! Very good visual acuity during the day after the Wavefront LASIK is therefore just a pleasant side-effect. For the correction of a refractive of error with glasses or contact lenses is the sphere (short or long sightedness) and if necessary offset the astigmatism (cylinder, axis). However, the human eye, like all optical apparatus has additionally more flaws of higher-order, called optical aberrations, such as for example the spherical aberration and the coma.
The aberrations of the eye can not be corrected by glasses or contact lenses, because the eye is movable and a Aberration correction must be augenzentriert. It remains as an option so only the correction using corneal refractive surgery (LASIK / LASEK), for which appropriate new excimer laser systems have been developed in recent years. In an aberration guided LASIK, the eye is first measured with an Aberrometer. The amount of corneal tissue to be removed in any place of the cornea is calculated from this measurement, the so-called ablation profile, and then the tissue removal by means of scanning-spot laser.
