20100292677 | Method for Determining Control Information for Photorefractive Corneal Surgery and Method for Providing Correction Information Required Therefor - A method for determining control information for controlling laser radiation irradiated onto the cornea of an eye to be treated photorefractively comprises correcting a corneal ablation profile, obtained by measuring optical properties of the eye, with the aid of correction information, the control information being formed on the basis of the corrected ablation profile thus produced. According to the invention, the correction of the ablation profile is performed in the spatial frequency domain. To this end, the ablation profile is transformed into a spatial frequency spectrum. Corrected amplitude or/and phase values are then determined for various discrete spectral components of the ablation profile on the basis of stored amplitude or/and phase correction information. Subsequently, the spatial frequency spectrum with the amplitude or/and phase corrected spectral components is backtransformed into the geometric spatial domain. The result is the corrected ablation profile. The amplitude and phase correction information in this case respectively represent for a number of spatial frequencies differing at least by the frequency value a predetermined relationship between values of the amplitude or/and phase at the relevant spatial frequency and corrected amplitude or/and phase values at this spatial frequency. | 11-18-2010 |
