Bangalore (Karnataka) [India], October 12 (ANI/PRNewswire): At less than 570 gms, the Remidio Instaref R20 is arguably the world's lightest and most portable auto refractometer based on the Shack-Hartmann Aberrometry technology. The product was unveiled, post FDA 510K registration, at the American Academy of Ophthalmology (AAO) 2022 conference in Chicago. Instaref R20 provides an objective spherical and cylindrical correction on the examined eye in less than 5 seconds. The device holds promise to thereby disrupt the screening for uncorrected refractive error market, valued at over USD 1 billion. WHO estimates ~2.2 billion people globally to have near or distant vision impairment. Unaddressed refractive error accounts for 44 per cent of global vision impairment. Population growth and aging are expected to increase this risk. The portability of Instaref R20 allows an eye care professional to refract patients with limited mobility, such as patients who use wheelchairs, or for a bedsid
