Patent ID: 8474974

Claim:
A method of determining a high order aberration induced by a change in geometrical configuration in an eye of a patient, comprising, through the use of a computer processor: inputting a first geometrical configuration of the eye; inputting an original set of coefficients for a basis function characterizing the first geometrical configuration of the eye, wherein the basis function can be separated into a product of a first set of radial polynomials and a first triangular function; inputting a second geometrical configuration of the eye; inputting 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 determining the induced high order aberration based on the transformed set of coefficients.
