It features Topcon’s patented Rotary Prism technology for highly accurate results. Its 360° rotatable touchscreen control panel allows the instrument to be installed in many different exam room configurations. By measuring this zone, the autorefractor can determine when a patient's eye properly focuses an image. The instrument changes its magnification until the image comes into focus. The process is repeated in at least three meridians of the eye and the autorefractor calculates the refraction of the eye, sphere, cylinder and axis. Recent studies report that autorefractor measurements without application of cycloplegia medication can result in significant overestimation of myopia. ^ "Medina A.: "Refractometro Electronico (Electronic Refractor)".
