Nidek Tonoref II — Used Autorefractor Keratometer Tonometer

The Nidek Tonoref II is Nidek’s combined autorefractor/keratometer/non-contact tonometer — a single chin-rest instrument that performs objective autorefraction, corneal keratometry, and non-contact IOP measurement without repositioning the patient between measurements. This used Nidek Tonoref II eliminates the need for a separate non-contact tonometer in the pre-testing lane, reducing the number of instrument positions per patient visit from three separate steps to one, and providing the three primary pre-testing data points — objective refraction, K-readings, and IOP — before the patient reaches the exam chair. The nidek tonoref ii is used in ophthalmology and optometry practices that want to streamline pre-testing throughput and reduce equipment footprint without sacrificing any of the three core pre-testing measurements. Available at $7,400 with a 90-day Digital Eye Center warranty.

Research published in Scientific Reports comparing portable tonometry devices against non-contact tonometry confirms that non-contact IOP measurement — the tonometry method built into the Nidek Tonoref II — remains the established clinical reference method for pre-testing IOP screening against which emerging portable alternatives are benchmarked.

Why Practices Choose the Nidek Tonoref II

• Three instruments in one — autorefraction, keratometry, and NCT — the Tonoref II performs objective autorefraction (sphere, cylinder, axis), corneal keratometry (K1/K2 readings), and non-contact tonometry (IOP) in a single instrument at one chin-rest position; practices that previously used three separate instruments — an autorefractor, a keratometer, and a non-contact tonometer — for pre-testing can consolidate to the Tonoref II and reduce the total instrument count in the pre-testing lane
• Non-contact tonometry — IOP screening without topical anesthetic — the Tonoref II uses an air-puff non-contact tonometer for IOP measurement; NCT does not require topical anesthetic drops, making it appropriate for pre-testing staff without clinical scope to administer medications; the air-puff method provides IOP screening data before the exam room without the preparation time or patient discomfort of Goldmann or contact tonometry
• Autorefraction — objective starting point for subjective refraction — the autorefraction component delivers the objective sphere, cylinder, and axis measurements used to set the phoropter starting position for subjective refraction; accurate autorefraction reduces chair time in the exam room and increases exam efficiency; the same autorefraction data is used for spectacle prescription verification and contact lens fitting starting points
• Keratometry — corneal curvature for contact lens and IOL workflows — the keratometry component measures K1 and K2 corneal radii and axes for contact lens base curve selection, toric axis alignment, and pre-surgical IOL power calculation; combining K-readings with autorefraction and IOP at a single pre-testing station provides the full contact lens fitting data set before the patient enters the exam room
• Workflow consolidation — fewer instrument positions per patient visit — eliminating a separate tonometer removes one instrument position from the pre-testing sequence; practices with high daily patient volume benefit from the reduction in per-patient pre-testing time; pre-testing staff can complete the entire AR/K/IOP sequence on a single instrument without reassigning patients between rooms or devices
• Used at $7,400 with 90-day warranty — 3-in-1 pre-testing at accessible pricing — the used Tonoref II at $7,400 provides the complete autorefraction/keratometry/tonometry pre-testing station for a fraction of purchasing three separate instruments new; 90-day warranty on parts and workmanship included

Clinical Applications

• Pre-testing workflow — complete refractive and IOP data before the exam room — the Tonoref II allows pre-testing staff to measure objective refraction, K-readings, and non-contact IOP in a single instrument pass; the complete pre-testing data set arrives with the patient before the phoropter or slit lamp is used, accelerating exam room workflow and increasing throughput in high-volume practices
• Glaucoma pre-screening — NCT IOP check at pre-testing — non-contact IOP measurement at pre-testing identifies patients with elevated IOP before they see the physician; the Tonoref II’s NCT component provides the IOP screening step that prompts clinical follow-up with Goldmann applanation in patients with elevated readings, supporting glaucoma case-finding in general ophthalmology and optometry practices
• Contact lens fitting — AR and K at one station — objective sphere and cylinder from the autorefractor and corneal radii from the keratometer at the same instrument provide the data needed for initial soft, toric, and RGP contact lens selection; practices with active contact lens fitting programs benefit from the integrated K-reading without a separate keratometer
• IOL planning support — K-readings for biometry workflows — the keratometry values from the Tonoref II supplement optical biometry data for IOL power calculation; practices can use Tonoref II K-readings as a cross-check measurement alongside their primary biometer for surgical planning
• Pediatric and general screening clinics — efficient multi-measurement capture — completing autorefraction, keratometry, and IOP screening at a single instrument reduces total pre-testing time and the number of instrument moves per patient; useful in pediatric eye care, school screening programs, and mobile clinical settings where minimizing the number of measurement steps per patient is a priority

Who This Is For

• Practices adding IOP screening to their autorefractor station — the Tonoref II replaces a standard AR/K unit with a combined AR/K/NCT instrument at a comparable price point; practices that currently perform IOP screening on a separate non-contact tonometer can consolidate to the Tonoref II and reduce total instrument count
• High-volume ophthalmology practices reducing pre-testing chair time — the single-station workflow eliminates patient repositioning between instruments; high-volume practices where pre-testing throughput is a clinical bottleneck benefit from the Tonoref II’s consolidated measurement sequence
• Optometry practices upgrading their pre-testing capability — the used Tonoref II at $7,400 gives optometry practices the autorefraction/keratometry/IOP pre-testing station used by high-volume ophthalmology lanes, at a used-instrument price with 90-day warranty; practices currently using a basic autorefractor without IOP screening can add NCT capability without purchasing a separate tonometer
• Multi-specialty clinics with combined diabetes and eye care programs — diabetic patients requiring annual refraction, contact lens follow-up, and IOP screening can have all three pre-testing measurements completed at the Tonoref II before seeing either the internist or the optometrist/ophthalmologist; the combined instrument supports shared-service clinic workflows where multiple specialties share pre-testing resources
