PlenOptika

PlenOptika is a Cambridge, Massachusetts medical device company that makes QuickSee, a handheld autorefractor that measures a person's eyeglass prescription in about ten seconds using wavefront aberrometry and machine-learning algorithms. Spun out of the Madrid-MIT M+Vision fellowship in 2014, the company set out to close the gap on uncorrected refractive error, a problem affecting more than a billion people worldwide. Its portable, clinic-quality device has been used by vision professionals and NGOs on over 5 million patients in more than 45 countries - and even flew aboard SpaceX's Polaris Dawn mission as the first handheld autorefraction device used in space.
