The Nidek/Marco OPD-Scan II ARK-1000 offers a complete state-of-the-art quality of vision assessment by combining corneal topography, wavefront, autorefraction, keratometry and pupillometry into one unique, impressive system. Using the principles of skiascopic phase difference, OPD-Scan II accurately assesses and determines refractive error map measurements. Furthermore, the corneal topography function utilizes Placido disc technology to analyze thousands of data points to plot corneal contour, shape and refractive power. By offering a variety of informative data maps, the OPD-Scan II provides detailed information on the total refractive error, wavefront, corneal shape, internal aberrations and overall visual quality of the eye, generating exceedingly accurate and reliable information for optical diagnostics. Also the Ark-1000 utilizes the principle of skiascopic phase difference for refractive error map measurement. The retina is scanned with an infrared light slit beam, and the reflected light is captured by an array of rotating photo detectors over a 360º area.
