A corneal surgery apparatus, for ablating a cornea with a laser beam to correct a refractive error more precisely, includes an ablation amount computing device for obtaining an ablation amount of the cornea for each of plural ablation steps based on a refractive error, a determining device for determining laser irradiation control data for each of the ablation steps based on the ablation amount, a corneal shape measurement device including a projecting optical system for projecting a target on the cornea, a photographing optical system for photographing an image of corneal reflection of the target, and a shape computing device for obtaining a corneal shape by processing the photographed target image, and a correcting device for comparing a predetermined ablation amount with an actual ablation amount based on the corneal shape measured after laser irradiation and for correcting the control data for the next step based on the comparison result.
