Patent ID: 8827449

Claim:
A system for establishing a prescription that mitigates or treats a vision condition of an eye in a particular patient, the system comprising: a first module comprising a tangible medium embodying machine-readable code that accepts a first ablation profile that corresponds to a first geometrical configuration of the eye in an evaluation context; a second module comprising a tangible medium embodying machine-readable code that determines an original set of coefficients for a basis function characterizing the first ablation profile, wherein the basis function is a member selected from the group consisting of a Zernike series, a Fourier series, and a Taylor series; a third module comprising a tangible medium embodying machine-readable code that accepts a second ablation profile that corresponds to a second geometrical configuration of the eye in a treatment context; a fourth module comprising a tangible medium embodying machine-readable code that determines a transformed set of coefficients for the basis function characterizing the second ablation profile, wherein the transformed set of coefficients are based on the first geometrical configuration of the eye, the original set of coefficients, and the second geometrical configuration of the eye, such that each coefficient of the transformed set of coefficients is based on a corresponding coefficient of the original set of coefficients and a resizing, cyclorotation, or decentration polynomial; and a fifth module comprising a tangible medium embodying machine-readable code that derives the prescription for the particular patient based on the transformed set of coefficients, wherein the prescription mitigates or treats the vision condition of the eye.
