Abstract: The present disclosure provides a three-lens IOL system including a first, anterior lens, a second, posterior lens rigidly connected to the first lens by at least one rigid member such that the second lens is a fixed distance from the first lens along an axis, a third, center, moveable lens positioned between the first lens and the second lens and adapted to move linearly along the axis anteriorly in a direction of the first lens or posteriorly in a direction of the second lens to change an optical power of the system, and an articulating actuator that contacts the moveable lens and a capsular bag of an eye when the IOL system is implanted in the capsular bag, the articulating actuator adapted to move the moveable lens linearly along the axis.

Abstract: A modular intraocular lens (IOL) with a ring configured to prevent glare artifacts. The ring includes a flange on the posterior rim, in which an anterior surface on the flange has a first profile and a posterior surface of the flange has a second profile non-parallel with the first profile. Non-parallel surfaces of the flange can be configured to defocus light transmitted at off-axis angles through an optic and the flange.

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.
