Claim:
A method of generating a refractive treatment shape for ameliorating a vision condition in an eye of a patient, the method comprising: determining a measurement surface aberration corresponding to a measurement surface of the eye, the measurement surface aberration being determined within a measurement surface boundary and comprising a measurement surface magnitude; determining a propagation distance between the measurement surface of the eye and a treatment surface; determining a treatment surface aberration based on the measurement surface aberration and the propagation distance, the treatment surface aberration being determined within a treatment surface boundary and comprising a treatment surface magnitude; and generating the refractive treatment shape based on the treatment surface aberration; wherein the refractive treatment shape is configured to ameliorate a high order aberration of the measurement surface aberration, and wherein a difference between the treatment surface magnitude and the measurement surface magnitude is proportional to the propagation distance, or a difference between the treatment surface magnitude and the measurement surface magnitude is proportional to a direction factor, or a difference between the treatment surface magnitude and the measurement surface magnitude is inversely proportional to a dimension of the measurement surface boundary, or a difference between the treatment surface magnitude and the measurement surface magnitude is inversely proportional to a squared radius of the measurement surface boundary.
