The purpose of this study was to determine the accuracy and repeatability of refractive errors obtained using three autorefractors based on different measurement principles, vis-à-vis, gold-standard retinoscopy. Accuracy of noncycloplegic, sphero-cylindrical refractive error of 234 eyes was obtained...
