摘要：
A corneal ablation system according to the present invention includes: an operation device for creating an integrated corneal ablation plan for correcting a shape and a curvature error of a cornea based on corneal status data； a laser control unit for controlling a laser module according to an ablation position and an ablation shape of the cornea based on the integrated corneal ablation plan transmitted from the operation device； and the laser module for generating a laser and transmitting the laser to an optical unit under control of the laser control unit, wherein the operation device uses information on a curvature error (low-order aberration) of the cornea, a corneal thickness distribution map, and a posterior corneal shape map, uses the corneal thickness distribution map with respect to the cornea except for a position of an eccentric posterior corneal cone by using the posterior corneal shape map so as to create a partial corneal ablation plan, executes the partial corneal ablation plan to maximally reduce thickness deviation in view of point symmetry so as to eliminate the eccentric posterior corneal cone, offsets curvature fluctuation generated during partial corneal ablation through myopic correction corneal ablation while concentrating the intraocular pressure at the thinned central portion of the cornea so as to generate the posterior corneal cone at the central portion of the cornea, so that the shape of the cornea is corrected into a symmetric corneal shape where the posterior corneal cone is concentrated at the central portion of the cornea, and creates and performs a corneal ablation plan for integrally correcting a defective shape and the curvature error by removing the curvature error through interlocking and executing the conventional low-order ablation with the corneal ablation.
