• The study shows that the subject’s response to the different lenses is influenced by the adaptation process that precedes each test.
• The neural mechanisms underlying the visual processing of different images, provided by these corrections, are still not fully understood.

A team of researchers from the Daza de Valdés Optics Institute and the company 2EyesVision has published a pioneering study in the journal Biomedical Optics Express about their experiments on the perception of bifocal intraocular lenses (IOLs) used to correct presbyopia. The work explores how optical power distribution and addition in bifocal lenses influence the visual quality perceived by patients, both at far and near distances. Using the SimVis Gekko visual simulator, the researchers have demonstrated that in simulation tests of different lenses, prior preparation is important to significantly improve the acceptance of multifocal lenses. This study offers valuable tools for lens designers and clinicians to optimize the adoption of these visual solutions.
