The Grand Seiko WAM-5500A Binocular Autorefractor/Keratometer can measure refraction and pupil diameter simultaneously in addition to all of the features present on its sister product, the WR-5100K. It also has the ability to dynamically measure accommodation making it ideal for pediatrics and research applications.
