“We are excited to see the results of this well-designed study because they help to validate the SVOne as a new clinical tool in our armamentarium for detecting refractive error in healthy eyes,” said Dr. Ciuffreda. “The smartphone-based SVOne literally puts the power to examine vision in the hands of the clinician. This can facilitate the ability to check vision both inside and outside the clinical setting, thereby addressing the need to expand the availability, efficiency, and accessibility of vision exams, for example in school screenings as well as underdeveloped and third-world countries.”
The SVOne, an FDA Class 1 exempt medical device, utilizes the iPhone’s computing power and camera to perform wavefront aberrometry and obtain the patient’s refractive error. In the published clinical testing, the spherical equivalent refractive findings measured with the SVOne were highly correlated with those obtained using subjective refraction (r^2 = 0.96) in a sample of 50 subjects. Further, the findings for the SVOne were not significantly different from the other objective and subjective techniques tested.
“The SVOne changes the autorefraction paradigm,” said Bernard Spier, MD, FAAO, a leading ophthalmologist in New Jersey who has been using the SVOne for both clinical and overseas work. “We have been performing subjective refraction in the clinic for years. What SVOne and other autorefractors offer is an objective measure of refractive error, which is thus less prone to investigator bias or error. What makes SVOne different, however, is its accessibility and affordability compared with an office-based platform.”
The results of the study are available here and will be published in the December issue of Optometry and Vision Science-the Journal of the American Academy of Optometry.
About Smart Vision Labs
We are a team of engineers, scientists, and problem solvers working to address the global vision crisis. Over 700 million people worldwide suffer from uncorrected refractive errors which can result in blindness and equate to hundreds of billions of dollars in lost annual global productivity. We believe that innovation can drive more accessible vision care for everyone. That’s why we launched our first product, the SVOne. The SVOne is a pocket-sized smartphone-based wavefront aberrometer and autorefractor. To date, the SVOne is used in over 250 eye clinics across the United States and in 23 countries and counting around the world.
