• Advanced Autorefraction with Retroillumination and Accommodation Measurements
    Rather than making a new version of an old autorefractor, NIDEK has re-engineered the ARK so more measurements are made – more accurately and more easily.

    Dual Zone Imaging Method
    The AR-1/ARK-1 uses two measurement rings so that refraction values are simultaneously acquired in a central zone (from 1 to 3.5mm), and a wide zone (from 1 to 6mm). These measurements provide valuable information about the regularity of the patient’s refraction from a day to a night pupil.
