Long-term performance of a diffractive-refractive trifocal IOL with centralized diffractive rings: 5-year prospective clinical trial.

Purpose: To report the 5-year visual, refractive, and patient-reported outcomes following implantation of a trifocal intraocular lens (IOL) during cataract surgery.

Setting: Csolnoky Ferenc University Hospital, Veszprém, Hungary.

Design: Prospective, longitudinal, single-center, interventional study.

Probability-Based Algorithm for Bearing Diagnosis with Untrained Spall Sizes.

Bearing spall detection and predicting its size are great challenges. Model-based simulation is a well-known traditional approach to physically model the influence of the spall on the bearing. Building a physical model is challenging due to the bearing complexity and the expert knowledge required to build such a model.

Implantation of a diffractive-refractive trifocal intraocular lens with centralized diffractive rings: Two-year results.

Purpose: To compare the optical performance and quality of life after implantation of a new progressively apodized diffractive multifocal intraocular lens (IOL) and report the visual and patient-reported outcomes and contrast sensitivity.

Setting: Csolnoky Ferenc Hospital, Veszprem, Hungary.

Design: Prospective case series.
