Abstract:
1. A method of controlling laser radiation irradiated onto a cornea of an eye to be treated photorefractively, the method comprising: obtaining a corneal ablation profile by measuring optical properties of an eye to be treated; transforming the corneal ablation profile into a spatial frequency spectrum; correcting an amplitude value for each of a plurality of discrete spectral components of the corneal ablation profile on the basis of stored amplitude correction information, wherein the stored amplitude correction information comprises a predetermined relationship between an amplitude value of a spatial frequency and a corrected amplitude value of the spatial frequency for a plurality of spacial frequencies; transforming the spatial frequency spectrum into a geometric spatial domain to obtain a corrected ablation profile utilizing the corrected amplitude values for each of the plurality of discrete spectral components; and controlling a laser source producing laser radiation irradiated onto the cornea of an eye with control information formed on the basis of the corrected ablation profile.
