Nidek RT-5100 — Used Auto Phoropter with Control Box

Why Practices Choose the Nidek RT-5100
Fully motorized remote operation — sphere, cylinder, and axis changes made from the control box; examiner never touches the phoropter, reducing chair time and improving workflow in high-volume lanes.
- Control box included — the RT-5100 ships with its matching control box, enabling complete remote operation; no separate controller purchase required.
- Wide prescription coverage — sphere from −19.00 D to +16.75 D and cylinder up to ±8.00 D covers standard and high-prescription patients without switching instruments.
- Built-in horizontal and vertical prism — integrated prism lenses support binocular vision testing and strabismus evaluation without auxiliary prism bars or clip-on prism sets.
- Full auxiliary lens set — cross-cylinder, pinhole, occluder, red/green filters, Maddox rod, and polarizing filters all internally housed; no manual accessory swapping during the exam.
- Motorized PD adjustment — pupillary distance set from the control box, matching patient PD quickly and accurately without mechanical adjustment by hand.
- Compatible with Nidek ARK autorefractors — links directly with Nidek ARK-series instruments to pre-load objective refraction data, shortening the subjective refinement phase.
- Quiet, balanced arm mount — low-torque design reduces operator effort when positioning; smooth motorized movement keeps the exam environment calm and supports patient comfort.
Clinical Applications
- Routine subjective refraction — distance and near prescription determination for spectacle and contact lens patients, with faster turnaround than manual flipping.
- High-volume practice lanes — motorized automation reduces per-patient exam time, increasing daily throughput without sacrificing refraction accuracy.
- Binocular vision and strabismus testing — integrated prism eliminates the need for external prism bars during cover tests and dissociated phoria measurements.
- ARK-assisted refraction — pre-loads Nidek ARK autorefractor data to give a starting point, accelerating the subjective refinement phase of the exam.
- Pediatric and low-cooperation patients — rapid motorized lens changes minimize the time needed to complete refraction on impatient or fatigued patients.
Who This Is For
- Ophthalmology and optometry practices modernizing a refraction lane with motorized automation at used pricing with a 90-day warranty.
- High-volume clinics looking to reduce per-patient exam time and increase daily capacity without sacrificing refraction quality.
- Practices with Nidek ARK instruments seeking a fully compatible motorized phoropter to close the loop from objective to subjective refraction.
- Multi-lane practices where remote control flexibility reduces the need for examiner movement between instruments during the exam.
