Abstract
A system for predicting post-operative vignetting in an eye of a subject includes a controller having a processor and a tangible, non-transitory memory on which instructions are recorded. The controller is in communication with a diagnostic module adapted to store pre-operative anatomic data of the eye as an eye model. The system includes a projection module and a ray tracing module selectively executable by the controller. The projection module is adapted to determine imputed post-operative variables of the eye based at least partially on the pre-operative anatomic data and the intraocular lens. The ray tracing module is adapted to calculate propagation of light through the eye. The ray tracing module is executed to determine a light distribution for respective visual field angles across a predefined field of view. The controller is configured to determine one or more post-operative vignetting parameters based at least partially on the light distribution.
