Comparator / control treatment
Central and peripheral refraction measured with a commercially available autorefractor, the Shin-Nippon NVision K5001, and a commercially available COAS aberrometer will be used as control measures. Both instruments have slightly been modified to enable the measurement of the peripheral optics of the eye.
