Abstract:
1. A method of calculating clinical performance of an ophthalmic optical correction using simulation by imaging a series of objects of different sizes by each of a plurality of eye optical systems, the method comprising: initially, determining a threshold, including: clinically measuring visual acuity, anatomical parameters and optical parameters of a population of eyes; providing an eye optical system corresponding to each eye in said population based on said parameters; and correlating clinically measured just-resolvable object sizes and just-resolvable object sizes calculated by the corresponding eye optical system; and subsequently: A. at an object distance, calculating a set of indicia of image quality, each indicium of the set of indicia corresponding to an object in the series of objects when it is imaged by a given one of the plurality of eye optical systems that include the ophthalmic optical correction; B. at the object distance, comparing the set of indicia to said threshold to determine a just-resolvable object size for the given one of the plurality of eye optical systems that include the ophthalmic optical correction; and C. repeating steps A and B for each eye optical system in the plurality of eye optical systems.
