Testing vision with physical and simulated multifocal corrections in an adaptive optics visual simulator

Abstract

Spatial Light Modulators (SLM) are increasingly used as active elements to simulate optical corrections, in particular multifocal presbyopic corrections, in Adaptive Optics (AO) systems. In this study we compared visual perception with lathed-manufactured multi-zone multifocal phase plates and through the same corrections simulated with an SLM in a custom-developed two-active-elements AO visual simulator used to measure and compensate for the eye¿s aberrations (with a deformable mirror) and to simulate the different multifocal solutions (with an SLM), respectively. We provide insights of the limits of SLMs to simulate such multifocal corrections.
