Patent ID: 7475986

Claim:
A method for treating or mitigating a vision condition of an eye in a particular patient, the method comprising: selecting a gauge of optical quality appropriate for the vision condition of the eye; inputting a patient parameter specific for the particular patient; determining an optical surface shape for the particular patient using the patient parameter specific for the particular patient with a compound modulation transfer function (CMTF), the compound modulation transfer function comprising a combination of modulation transfer functions (MTF's) at a plurality of distinct frequencies; and mitigating or treating the vision condition of the eye in the patient by administering to the patient a procedure selected from the group consisting of: ablating a corneal surface of the patient to provide a corneal surface shape that corresponds to the optical surface shape, providing the patient with a contact lens or spectacle lens that has a shape that corresponds to the optical surface shape, and providing the patient with an intra-ocular lens that has a shape that corresponds to the optical surface shape; wherein the gauge of optical quality comprises a compound modulation transfer function (CMTF) parameter.
