VERGENCE WEIGHTING SYSTEMS AND METHODS FOR TREATMENT OF PRESBYOPIA AND OTHER VISION CONDITIONS

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 an optical metric such as a compound modulation transfer function (CMTF).

主权项

1. A method for treating a vision condition of an eye in a particular patient, the method comprising:
receiving a vision requirements specification selected for the particular patient, the vision requirements specification comprising a first weighting value for a first viewing distance within a vergence range and a second weighting value for a second viewing distance within the vergence range; determining an optical surface shape for the particular patient, the optical surface shape based on the vision requirements specification and an optical metric; and treating the vision condition of the eye of the particular patient by providing a treatment to the patient, the treatment comprising a shape that corresponds to the optical surface shape.
