Validation of a Predictive Model of Clinical Measures of Visual Function

Abstract

At the 1992 NAVS/OVO meeting1, we introduced a phenomenological model (called Expected Visual Outcome) which is intended to predict clinical function (e.g., contrast sensitivity, through-focus-acuity, etc.) base on in-vitro modulation transfer function (MTF) measurements of intraocular lens (IOL) performance2. In this paper, we discuss the validation of this model using individual patient data derived from the AMO ArrayTM multifocal IOL clinical study3.
