Compound modulation transfer function for laser surgery and other optical applications

摘要

Methods, devices, and systems establish an optical surface shape that mitigates or treats a vision condition in a patient. An optical surface shape for a particular patient can be determined using a set of patient parameters for the specific patient by using a compound modulation transfer function (CMTF). The compound modulation transfer function can include a combination of modulation transfer functions (MTF's) at a plurality of distinct frequencies.

主权项

1. A system for establishing an optical surface shape that mitigates or treats a vision condition of an eye in a particular patient, the system comprising:
an input that accepts a set of patient parameters; and a module comprising a tangible non-transitory medium embodying machine-readable code that determines an optical surface shape for the particular patient based on the set of patient parameters, using a composite optical metric, wherein the composite optical metric comprises a first compound modulation transfer function (CMTF) parameter and a second parameter, the first parameter based on a CMTF comprising a combination of modulation transfer functions (MTF's) at a plurality of distinct frequencies.
