The purpose of the present invention is to provide an apparatus for determining an amount of corneal ablation, which can calculates an amount of corneal ablation in order to perform an operation for correcting ametropia adequately, based on a corneal shape and/or an eye refractive power. Another object of the present invention is to provide a surgical apparatus for a cornea, by which the surgical operation can be performed efficiently based on the obtained amount of corneal ablation. The apparatus for determining an amount of corneal ablation, based on which surgical operation for correcting ametropia is performed, the apparatus comprises a first input unit (53) for inputting data of a pre-operative corneal shape of a patient's eye; a second input unit (52, 53, 54) for inputting data of a post-operative corneal shape of the eye, to be estimated (to be a target for correcting); an ablation amount calculating unit (54) for calculating data of a corneal ablation amount of the eye, in a manner of calculating data of an ablation amount in a symmetric component and data of an ablation amount in an asymmetric component separately and respectively, based on the data inputted by the first input unit and the second input unit; and an output unit (56, 59a, 59b) for outputting results calculated by the ablation amount calculating unit.
