The SimVis technology to simulate multifocal corrections relies on fast tunable lenses (temporal multiplexing). We propose a method to generate and evaluate the temporal profile describing real multifocal lenses (segmented refractive, trifocal diffractive and extended depth of focus) based on the fitting of the through-focus (TF) optical quality of the multifocal component of a given multifocal lens to a linear combination of TF optical quality of monofocal lenses viable with a tunable lens. Visual Strehl ratio and TF simulated images obtained with estimated time coefficients closely matched those predicted with the M-IOL. The study also investigates the effects of temporal sampling, varying pupil size, monochromatic aberrations, longitudinal chromatic aberrations and temporal dynamics on SimVis.

The jury of Premios Rey Jaime I, one of the most prestigious awards in Spain, announced the winners of the 2017 edition in a formal event at the Palau de la Generalitat Valenciana. Susana Marcos has received the Premio Rey Jaime I in “New Technologies” for her “important contributions to the field of the physics of vision and, in particular, her studies on imaging and ocular diagnostics that had led to the development of new intraocular lenses and the detection of ocular diseases.”
