Patent ID: 8057037

Claim:
A system for ameliorating a vision condition in an eye of a patient, the system comprising: an input module that accepts a measurement surface aberration, the measurement surface aberration based on a wavefront aberration of the eye, the wavefront aberration corresponding to a measurement surface that is disposed at or near a pupil plane of the eye, wherein the measurement surface aberration comprises a measurement surface wavefront map; a transformation module that derives a treatment surface aberration, the treatment surface aberration corresponding to a treatment surface that is disposed at or near an anterior surface of a cornea of the eye, the treatment surface aberration derived from the measurement surface aberration using a difference between the measurement surface and the treatment surface, wherein the treatment surface aberration comprises a treatment surface wavefront map derived at least in part by local slope scaling of the measurement surface wavefront map; an output module that generates a refractive treatment shape based on the treatment surface aberration; and a laser system that directs laser energy onto the eye according to the refractive treatment shape so as to reprofile a surface of the eye from an initial shape to a subsequent shape, the subsequent shape having correctively improved optical properties for ameliorating the vision condition.
