Researchers at the Instituto de Optica in Spain have developed a hand-held device that allows patients to test intraocular lens (IOLs) designs prior to implantation.
Called the simultaneous vision simulator, or SimVis, the device reportedly allows patients to experience how a certain implanted lens would affect their vision by just looking through it. The SimVis reportedly uses an optoelectronic tunable lens that changes shape in response to an applied electric current.
The researchers are reportedly now working on a binocular version of the SimVis that could simulate different lenses in each eye.
The research was recently published in the journal Optica.
