Abstract

In 1965, Campbell and Green made use of the concept that the MTF of the human dioptric could be inferred from the ratio of sign-wave to interferometric contrast sensitivity measurements¹. Below, we employ the same procedure, in reverse, to suggest a phenomenological algorithm for predicting the "clinical significance" (e.g., letter or sign-wave contrast sensitivity) of changes made to the human dioptric (e.g., multifocal IOL implant). This algorithm can also be used to predict the Through- Focus-Capability (acuity v.s. defocus), with the potential for studying expected changes with light intensity and object contrast. A comparison of predictions to early clinical data derived from Allergan's randomized AMO Array^TM multifocal clinical study, demonstrates the plausibility of this approach.
