Uncovering the origin of negative dysphotopsia

Abstract

Negative dysphotopsia is a bothersome shadow in the peripheral visual field that can occur after cataract surgery. This thesis aims to uncover its origin by creating and analyzing atomically accurate models of the eye. To that end, the ocular anatomy of pseudophakic patients with and without negative dysphotopsia is extensively evaluated using ophthalmic measurements and MRI scans. Furthermore, methods are designed to determine peripheral anatomical characteristics of the eye. The measurements and methods are combined and used for optical ray tracing simulations. The simulations show a stronger local reduction in peripheral retinal illumination in the eyes of patients with negative dysphotopsia.
