Intraocular Lens Selection via Ray Tracing
Summary
USPTO published patent application US20260090710A1 on April 2, 2026, disclosing a system and method for selecting intraocular lenses using ray tracing through pseudophakic eye models. The invention enables surgeons to pre-operatively compare multiple lens options and select the preferred lens based on simulated optical performance metrics. Inventors include George Hunter Pettit, Mark Andrew Zielke, John Alfred Campin, Martin Gruendig, and Daniil Nekrassov.
What changed
This patent application discloses a system and method for selecting a preferred intraocular lens (IOL) for implantation into an eye. The system uses a controller in communication with a diagnostic module that stores pre-operative anatomic eye data as an eye model. For each candidate IOL, the system determines imputed post-operative variables via a projection module, generates a pseudophakic eye model incorporating those variables, and executes a ray tracing module to determine at least one optical metric. The preferred IOL is selected based on comparison of these metrics.
This is a published patent application rather than an enforceable regulation or guidance. Medical device manufacturers and ophthalmic equipment developers may wish to review the claims to assess potential infringement risks or licensing opportunities. No compliance deadlines or penalties are associated with this publication. The application (No. 19414352) was filed December 10, 2025.

Abstract
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.
