Abstract:
1. A method of generating a refractive treatment shape for ameliorating a vision condition in an eye of a patient, the method comprising: determining a first wavefront measurement corresponding to the pupil plane of the eye, the first wavefront measurement comprising a first wavefront boundary and a first set of wavefront coefficients; determining a propagation distance between the pupil plane of the eye and a treatment surface; determining a propagated wavefront measurement corresponding to the treatment surface based on the first wavefront measurement and the propagation distance, the propagated wavefront measurement comprising a second wavefront boundary and a second set of wavefront coefficients; and generating the refractive treatment shape based on the propagated wavefront measurement, wherein the refractive treatment shape is configured to ameliorate a high order aberration of the first wavefront measurement which comprises the first set of wavefront coefficients; and wherein a difference between the first set of wavefront coefficients and the second set of wavefront coefficients is proportional to a value selected from the group consisting of the propagation distance, a direction factor, an inverse of a dimension of the first wavefront boundary, and an inverse of a squared radius of the first wavefront boundary.
