Wavefront measurements of eyes are typically taken when the pupil is in a first configuration in an evaluation context. The results can be represented by a set of basis function coefficients. Prescriptive treatments are often applied in a treatment context, which is different from the evaluation context. Hence, the patient pupil can be in a different, second configuration, during treatment. Systems and methods are provided for determining a transformed set of basis function coefficients, based on a difference between the first and second configurations, which can be used to establish the vision treatment. |

1. A system for correcting or treating presbyopia with a prescription that mitigates or treats a vision condition of an eye, 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, the first ablation profile characterized by an original set of coefficients for a basis function, wherein the basis function is a member selected from the group consisting of a Zernike series, a Fourier series, and a Taylor series; a second module comprising a tangible medium embodying machine-readable code that determines a second ablation profile that corresponds to a second geometrical configuration of the eye in a treatment context, the second ablation profile characterized by a transformed set of coefficients for the basis function that is 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 third module comprising a tangible medium embodying machine-readable code that establishes the prescription for the treatment or correction of presbyopia based on the transformed set of coefficients. |
