Nidek Tonoref RKT-7700 — Used Auto Ref / Keratometer / Tonometer Combo
The Nidek Tonoref RKT-7700 is Nidek’s tri-functional pre-exam workstation — auto-refraction, keratometry, and non-contact tonometry (NCT) in a single tabletop instrument. This used nidek tonoref rkt-7700 ships ready for high-throughput optometry pretest workflows at sub-$6K Used pricing.
The Tonoref RKT-7700 covers the standard pretest workflow — auto-ref provides the objective starting point for subjective phoropter refraction; K-readings support IOL and CL planning; non-contact tonometry provides IOP measurement without anesthesia or contact. Three pre-exam stations consolidated into one tabletop footprint.
According to a National Library of Medicine-indexed study (Indian J Ophthalmol, 2026), ophthalmic-instrument repeatability depends heavily on operator-instrument interaction.
