Nidek ARK-1S

This used Nidek ARK-1S is a compact autorefractor and keratometer built to provide quick, objective refraction and corneal measurements as part of routine eye examinations. It captures sphere, cylinder, axis, and keratometric readings efficiently, giving practitioners a reliable starting point before subjective refraction or contact lens fitting. As a member of Nidek's respected ARK series, the ARK-1S is valued for its practical, no-frills approach to pre-testing. The unit's automated alignment and measurement capture help reduce variability between operators and make it easier to obtain consistent results across a range of patients, including those who have difficulty fixating steadily. By combining refraction and keratometry functions in a single instrument, the ARK-1S helps practices simplify their pre-testing workflow and make better use of limited exam room space. It is well suited to general optometric practices, vision screening programs, and smaller clinics that need dependable combination testing without a large equipment footprint. This ARK-1S is sold as a pre-owned unit that has been in regular clinical service, and it will show the expected cosmetic wear of an actively used instrument. It remains a functional and economical choice for practices seeking a straightforward autorefractor-keratometer to support day-to-day patient care.
