Auto ref/keratometers

NIDEK has launched a new series of auto ref/keratometers, the ARK-1s, ARK-1a, and ARK-1. “The ARK-1s is the most advanced, providing additional measurements including visual acuity measurement with/ without glare test, opacity assessment and accommodation measurement,†said a company spokesman. “The ARK-1a includes opacity assessment and accommodation measurement. With a number of technological advancements, these units surpass conventional auto refractor/ keratometers. The ability to measure central area refraction and wide area refraction of up to 6mm diameter determines the effect of pupil size on refraction. “The artificial intelligence algorithm automatically reduces the accommodation measurement time in cases with slow or weak accommodation. Measurement of keratometry with mire rings reduces lid artifacts during measurement,†the NIDEK spokesman said. www.nidek.com
