Patent ID: 8409178

Claim:
A method of evaluating a treatment table for use in an ophthalmologic refractive surgery for a patient, the method comprising: inputting a treatment table containing laser ablation instructions for treating the patient into a treatment instructions module; determining a simulated ablation for the patient based on the laser ablation instructions with a simulation ablation module; inputting a pupil dimension of the patient into a pupil dimension module; determining an expected optical refraction for the patient based on the pupil dimension and the simulated ablation with an expected optical refraction module, wherein the expected optical refraction for the patient is dependent on a sphere ophthalmic term characterized by a set of second radial order polynomial terms, a cylinder ophthalmic term characterized by the set of second radial order polynomial terms, and an axis ophthalmic term characterized by the set of second radial order polynomial terms, and wherein the expected optical refraction profile is independent of a piston ophthalmic term characterized by a zero radial order polynomial term, an x-tilt ophthalmic term characterized by a set of first radial order polynomial terms, and a y-tilt ophthalmic term characterized by the set of first radial order polynomial terms; inputting an intended optical refraction for the patient into an intended refraction module, wherein the intended optical refraction for the patient is dependent on a sphere ophthalmic term, a cylinder ophthalmic term, and an axis ophthalmic term, and wherein the intended optical refraction profile is independent of a piston ophthalmic term, an x-tilt ophthalmic term, and a y-tilt ophthalmic term; and evaluating the treatment table by comparing the expected and intended optical refractions for the patient with a comparison module.
