MONDAY, Feb. 11, 2019 (HealthDay News) — Visual simulation in an adaptive optics (AO) environment can capture optical and visual performance with real multifocal intraocular lenses (M-IOLs), according to a study published online Feb. 7 in Scientific Reports<\/i>.<\/p>\n
Maria Vinas, Ph.D., from the Institute of Optics in Madrid, and colleagues compared through-focus (TF) optical and visual quality produced by real M-IOLs projected onto a patient’s eye with the same designs simulated with a spatial light modulator (SLM) or an optotunable lens working in temporal multiplexing mode (SimVis technology). Using a custom-made multichannel three-active optical-elements polychromatic AO visual simulator in monochromatic light, researchers performed measurements on seven cyclopleged patients.<\/p>\n
Performance of the real IOLs, SLM, and SimVis technology simulations on bench was demonstrated using double-pass imaging on an artificial eye. The researchers found that TF performance demonstrated good general correspondence for the real and simulated M-IOLs, optically (on bench) and visually (measured visual acuity in patients).<\/p>\n
“Visual simulators are an ideal technique to provide patients with a new realistic experience of multifocality before the implantation of a new intraocular lens,” a coauthor said in a statement. “In addition, if the simulator is miniaturized and has a more practical design than the ones currently available in the market, benefits could multiply.”<\/p>\n
