Abstract

We have developed a phenomenological model for prediction of the expected relative changes in measures of visual function based on in vitro measurements of the modulation transfer function and the human threshold retinal response. This algorithm can be used to predict the resultant changes in contrast sensitivity due to changes made to the human dioptric elements. This algorithm can also be used to study the through-focus capability with the potential for evaluating the expected changes with light intensity and object contrast. The results obtained from this model will be compared with the clinical data derived from Allergan's randomized AMO Array multifocal intraocular lens implant clinical study.
