Abstract:
1. 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 geometrical configuration of the eye; 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 geometrical configuration, wherein the basis function can be separated into a product of a first set of radial polynomials and a first triangular function; a third module comprising a tangible medium embodying machine-readable code that accepts a second geometrical configuration of the eye, wherein a difference between the first geometrical configuration of the eye and the second geometrical configuration of the eye comprises a pupil dilation; a fourth module comprising a tangible medium embodying machine-readable code that determines a transformed set of coefficients for the basis function, 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 corresponding 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.
