Nidek ARK-560A

This used Nidek ARK-560A is an autorefractor and keratometer combination unit that provides objective refraction and corneal curvature data in a single chairside measurement session. It is designed to give practitioners a quick, reliable starting point for spectacle prescriptions and contact lens evaluations, reducing the guesswork and time involved in manual refraction. The ARK-560A builds on Nidek's long track record in this equipment category with refined optics and measurement stability. Clinically, the unit supports a wide range of exam types, from routine vision checks to pre-cataract surgery biometry planning, by delivering sphere, cylinder, axis, and keratometric readings quickly and with minimal patient cooperation required. Its autotracking and auto-shot capture help technicians obtain consistent results even with less cooperative or younger patients, and the combined functionality reduces the number of separate instruments needed in the exam lane. Many optometry and ophthalmology practices have used the ARK-560A as a dependable daily driver for pre-testing. Sold here as a pre-owned unit, this ARK-560A has been used in a clinical setting and will show typical signs of service wear, though it remains in working order for continued diagnostic use. It is a solid choice for practices wanting to add a combination autorefractor-keratometer at an accessible price point.
