PURPOSE The SVOne is a portable Hartmann-Shack wavefront aberrometer that can be attached to a smartphone to determine the refractive error of the eye objectively. The aim of the present study was to compare the findings of the SVOne with retinoscopy, subjective refraction, and two commercially available autorefractors (Topcon KR-1W and Righton Retinomax-3). METHODS Refractive error was assessed both with and without cycloplegia in 50 visually normal, young adults using the five techniques… CONTINUE READING
