An ophthalmic system for generating an ocular model of an eye includes an optical coherence tomography (OCT) device, an aberrometer, and a computer. The OCT device detects OCT light reflected from the eye. The aberrometer detects aberrometer light reflected from the eye. The computer generates the ocular model of the eye according to the reflected OCT light. The ocular model includes parameters describing the eye. The parameters include lens parameters that describe the lens of the eye. The computer determines an OCT-based wavefront according to the ocular model, determines an aberrometer-based wavefront according to the reflected aberrometer light, and compares the OCT-based and the aberrometer-based wavefronts. If the wavefronts differ beyond a predefined tolerance, the computer adjusts one or more values assigned to the parameters until the wavefronts satisfy the predefined tolerance. At least one adjusted value is assigned to a lens parameter.

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.

A system and method for selecting a preferred intraocular lens, for implantation into an eye, 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 controller is configured to determine respective imputed post-operative variables for each of a plurality of intraocular lenses, via a projection module. A respective pseudophakic eye model is generated for each of the plurality of intraocular lenses by incorporating the respective imputed post-operative variables into the eye model. A ray tracing module is executed in the respective pseudophakic eye model to determine at least one respective metric for the plurality of intraocular lenses. The preferred intraocular lens is selected based on a comparison of the respective metric.
