Abstract
The optical quality of the eye cornea surface after performing the laser vision correction essentially depends on the characteristic roughness scale (CRS) of the ablated surface, which is mainly determined by the absorption coefficient of the cornea at the laser wavelength. Thus, in the case of using an excimer ArF laser the absorption coefficient is equal to , the darkening by the dissociation products takes place, and the depth of the roughness relief can be as large as . Under irradiation with the Er : YAG laser the clearing is observed due to the rupture of hydrogen bonds in water, and the relief depth exceeds . It is shown that the process of reepithelization that occurs after performing the laser vision correction leads to the improvement of the optical quality of the cornea surface.
