ABSTRACT:
The purpose of the present invention is to provide a corneal-ablation-data determining apparatus and a corneal-ablation-data determining program capable of controlling corneal ablation amount distribution and expanding ablation applicability. In the present invention, the corneal-ablation-data determining apparatus for use in keratorefractive surgery for ablating a corneal surface to correct a refractive error has input means for inputting measurement data on any one of wavefront aberration distribution and refractive power distribution of a patient's eye, decentering means for decentering a reference axis being a calculation reference for a corneal ablation amount, and calculation means for obtaining the corneal ablation amount based on the measurement data and data on eccentricity of the reference axis.
