In the August 2016 issue of Optica, a journal published by the Optical Society, researchers described a new hand-held device called the simultaneous vision simulator, or SimVis, that allows patients to experience how different intraocular lenses used to treat cataracts would affect their vision by simply looking through the device.

As one of the article’s authors, Carlos Dorronsoro, explained, “The decision on which intraocular lens is implanted during cataract surgery is typically based on the explanations and experience of the surgeon. But it is difficult for patients to imagine the new visual experience provided by some of these lenses, [and] therefore, it is very difficult to make the decision.” With the new device, patients can test different solutions before surgery and choose the one that best suits their needs.
