Nidek ARK-700A — Used Autorefractor Keratometer Combo Unit
The Nidek ARK-700A is a combination autorefractor + keratometer that streamlines pre-exam refractive workup into a single instrument. This used nidek ark-700a ships ready as a complete combo unit — operators can read objective refraction and corneal-curvature K readings simultaneously, or one at a time, with a single patient alignment.
The ARK-700A stores up to 20 readings per eye and averages three or more measurements automatically — a key feature for reliable refractive data on patients with variable accommodation. Single-target alignment and IOL-mode compatibility make it suitable for both routine refractive workups and pre/post-operative cataract patients with intraocular lens implants. Auto-print output streamlines chart documentation.
According to a National Library of Medicine-indexed study (Indian J Ophthalmol, 2026), agreement between objective autorefraction and subjective phoropter refraction depends heavily on instrument quality and operator-instrument interaction — supporting the multi-measurement-averaging workflow the ARK-700A was built to provide.
Why Practices Choose the Nidek ARK-700A
Combo autorefractor + keratometer — both measurements in a single patient alignment; saves chair-time vs separate instruments.- Simultaneous or sequential measurement modes — operator picks the workflow that fits the patient.
- Up to 20 readings stored per eye — automatic averaging when 3+ measurements taken; reduces variability bias.
- Single-target alignment — fast, intuitive operator workflow.
- IOL mode — measures patients with intraocular lens implants without alignment errors.
- Auto-print output — direct hard-copy results for chart insertion.
- L/R distinction display — clear left-eye / right-eye comparability.
- Nidek service network — extensive US parts and service support.
Clinical Applications
- Pre-exam refractive workup — objective starting point for subjective refraction in optometry and general ophthalmology.
- Cataract pre-op K readings — corneal curvature data for IOL power calculation.
- Post-cataract refractive verification — IOL-mode measurement on pseudophakic patients.
- Contact lens fitting — keratometric base curve data for fitting.
- Refractive surgery screening — baseline corneal curvature documentation.
- Pediatric and screening clinics — fast objective refraction for non-cooperative patients.
Who This Is For
- Optometry practices wanting a Nidek-quality autorefractor + keratometer combo.
- General ophthalmology offices needing objective refraction starting point for chair-side subjective refinement.
- Multi-doctor groups standardizing on Nidek ARK-series across exam lanes.
- Practices replacing an older standalone autorefractor or standalone keratometer with a combo unit.
- Buyers wanting Nidek build quality at a sub-$5K used price point.
