Righton Retinomax K-Plus 5 Handheld Auto Ref/ Keratometer with Charging Station – Used

Description

Retinomax K-Plus 5 — Used Righton Handheld Autorefractor and Keratometer with Charging Station

The Retinomax K-Plus 5 is Righton’s fifth-generation handheld autorefractor/keratometer — the clinical standard for objective refraction and corneal curvature measurement in patients who cannot use a standard tabletop instrument. This used Retinomax K-Plus 5 includes the charging station and 1 battery pack, and delivers autorefraction and keratometry while the examiner holds the device in any position — kneeling at floor level, working bedside, or examining a child in a parent’s lap. The automatic axis compensation gyroscope corrects for instrument tilt, and auto-capture alignment triggers measurement at 0.124 seconds without manual activation. The K-Plus designation confirms full keratometry capability alongside autorefraction: sphere measurement from -20.00D to +23.00D, cylinder ±12.00D, and corneal radius from 5.00–11.00mm — covering the full clinical range of refractive error and corneal curvature in a single handheld instrument. The Retinomax K-Plus 5 remains the only handheld instrument that provides validated autorefraction and keratometry for patients who cannot be positioned at a tabletop device.

Research published in the National Library of Medicine confirms the accuracy of Retinomax K-Plus platform measurements in measuring refractive error in pediatric populations — validating its role as the objective refraction standard of care for children, non-cooperative patients, and individuals with cognitive or physical limitations.

Covered by a 90-day warranty on parts and workmanship.

Why Practices Choose the Retinomax K-Plus 5

• Fully handheld autorefraction and keratometry — sphere from -20.00D to +23.00D and cylinder ±12.00D cover the full clinical refractive range; corneal radius 5.00–11.00mm covers the full population for contact lens and pre-surgical keratometry; all measured while the examiner holds the instrument in any position with no chin rest or table required.
• Automatic axis compensation gyroscope — the K-Plus 5’s internal gyroscope measures the degree of instrument tilt and automatically corrects the cylinder axis reading regardless of how the examiner holds the device; valid axis data is obtained even when measuring a child on the floor, a patient in a wheelchair, or a supine hospital patient.
• Auto-capture alignment — 0.124-second measurement — the device triggers automatically when proper alignment is achieved; no manual button press during examination; 0.124-second acquisition minimizes the impact of patient movement and reduces measurement failures in non-cooperative patients.
• Auto Quick mode for maximum speed — if no measurement is made within 6 seconds, the device enters Quick mode with 0.07-second measurement acquisition; AQ is marked on the printout; enables rapid screening in high-volume pediatric programs where individual measurement time matters.
• Pediatric-specific design features — the K-Plus 5 includes Child Mode: a melody plays during measurement and a changing color display on the outside and inside of the device maintains children’s attention; designed specifically for cooperative measurement in infants and young children without sedation or cycloplegia.
• Built-in printer — immediate on-site results — the integrated printer produces refraction and keratometry printouts at point of care; no software, cable, or external printer required; results available for the chart immediately after measurement.
• Adjustable viewfinder diopter ±8D; arm 0–135° — the viewfinder adapts to the examiner’s refractive error without glasses; the viewfinder arm tilts from 0 to 135° for measurement from any angle regardless of patient posture or examiner position.
• Used pricing with 90-day warranty — complete Retinomax K-Plus 5 set with charging station at $8,800 with a 90-day warranty on parts and workmanship.

Clinical Applications

• Pediatric refraction — the primary clinical application for the Retinomax K-Plus 5; objective sphere, cylinder, and axis in children from infants through school age without tabletop positioning; essential for amblyopia screening, refractive error documentation, and spectacle prescription in children who cannot complete subjective refraction.
• Special needs and cognitive disability refraction — patients with autism spectrum disorder, Down syndrome, cerebral palsy, and other cognitive or physical conditions can receive objective refraction at any angle, distance, or seating position the examiner can access.
• Ambulatory and bedside examination — hospital patients, nursing home residents, post-operative patients restricted to supine positioning, and individuals in wheelchairs receive objective refraction without transfer to an examination chair; the Retinomax brings the refraction to the patient.
• Pediatric amblyopia screening programs — school vision screening, pediatric primary care office screening, and community eye health programs use the Retinomax K-Plus 5 for rapid objective refraction across large numbers of children in a time-efficient workflow.
• Pre-surgical keratometry in non-cooperative patients — K-Plus keratometry provides corneal curvature data for IOL power calculation and contact lens selection in pediatric cataract surgery, keratoconus assessment, and refractive surgical planning where standard keratometers cannot be used.
• Mobile eye care and outreach programs — the Retinomax K-Plus 5 travels in a bag; handheld battery operation and built-in printer bring objective refraction to schools, community centers, and mobile clinic sites without fixed equipment or power outlets at the exam station.

Who This Is For

• Pediatric ophthalmologists and optometrists — the Retinomax K-Plus 5 is the standard instrument for objective refraction in pediatric practice; practices managing amblyopia, strabismus, and pediatric refractive error depend on it for accurate objective baseline measurements in children.
• Special needs and developmental optometry practices — non-cooperative patients require handheld refraction capability; the Retinomax K-Plus 5 is designed specifically for this population and has no comparable alternative for truly handheld kerato-refraction.
• Hospital-based ophthalmology departments — bedside and ward refraction for hospitalized patients, ICU consultations, and post-operative assessments where patients cannot access standard examination equipment.
• Mobile eye care and outreach programs — handheld battery operation and built-in printer enable objective refraction at any location; the Retinomax brings full ARK capability to any setting in a single portable instrument.
