Tomey Multifunction unit MR-6000

In optometry pre-examination, the MR-6000 brings objective refraction and corneal measurements to the same patient position. Sphere, cylinder, and axis provide a starting point for refractive assessment, while keratometry adds the curvature of the anterior cornea. The selectable sequence suits a room where a trained operator gathers measurements before the clinician reviews them. Automatic alignment supports acquisition, and the motorised chin rest accommodates positioning at the instrument.

Ophthalmology consultations can use the pressure and pachymetry functions together. Air-puff tonometry supplies intraocular pressure, while central thickness provides the input for a thickness-adjusted reference value. This combination supports the pressure-assessment component of glaucoma screening. Each result retains its own meaning, so measured pressure, central thickness, and the calculated reference remain distinct parts of the examination.

For corneal and contact-lens assessment, the topographic maps show how anterior surface curvature varies across the measured area. White-to-white and pupil measurements add visible-eye dimensions to that surface record. Fourier presentation supports review of the shape components, and the clinician can relate these findings to the planned refractive or lens assessment. The electrical cone exchange keeps the selected measurements within the same examination position.

Ocular-surface consultations use the included meniscus, gland, redness,s and blink observations to examine tear-related characteristics. Infrared gland images and the 10-second blink recording contribute different views of the surface system. An optional TSAS licence adds ring-reflection stability analysis during sustained eye opening. Stored data, image export, rt and printed results give the reviewing clinician a record of the selected examinations, whether the session centres on refraction, corneal shape, pressure, or ocular-surface observation.

Mode changes at the examination position

Electrical cone exchange keeps the transition between measurement systems inside the instrument. The patient remains at the chin and forehead supports while the operator selects the next examination. With the exchange taking about 4 seconds, the mechanical change has a defined place in the sequence, and the touchscreen remains the control point for the following acquisition.

Optical and pressure findings in one examination

The unit gathers refraction, anterior corneal shape, central thickness, and intraocular pressure at one seated position. These measurements answer different questions about the eye, and their combined availability gives the clinician several related findings to interpret. The operator can build a session around the selected functions while keeping positioning, viewing, and output within the same instrument assembly.

Automated positioning with direct operator control

Image-recognition alignment and automatic acquisition assist the measurement process. Joystick movement and touchscreen controls remain available to the operator, while the powered chin rest supports patient positioning. This arrangement combines automated alignment with direct control of the examination, making the selected mode and its acquisition state accessible at the front of the instrument throughout the session.

A refraction mode for interrupted fixation

Quick Ref addresses the acquisition stage when the patient finds sustained fixation difficult. Its intended use includes examinations involving children and nystagmus, giving the operator a mode suited to those fixation conditions. Refraction remains expressed as sphere, cylinder and axis, so the recorded result retains the familiar form used during the subsequent refractive assessment.

Thickness information alongside pressure

Central pachymetry and non-contact tonometry contribute separate measurements to pressure assessment. The adjustment function then uses corneal thickness to calculate an additional reference value. Keeping the measured thickness, measured pressure,e and adjusted reference within the examination supports a structured review of the findings, with the clinician interpreting each value in its proper role.

Ocular-surface observations within the standard unit

The included application records tear meniscus, infrared gland images, conjunctival redness and blinking. These observations cover tear volume-related information, gland appearance, surface redness and eyelid movement within the same device. They give an ocular-surface consultation several forms of evidence to review, while the optional TSAS licence extends the assessment to time-dependent changes in reflected ring images.

Paper and digital examination records

A thermal printer provides an immediate paper record, and the integrated database retains examination data. File export supports numerical, image and report formats, giving the operator several output types for the selected findings. USB and Ethernet interfaces form the wired connection options; a wireless-equipped configuration also provides WLAN for its supported communication functions.

Defined supplies for routine use

The instrument uses replaceable chin-rest paper and thermal-printer rolls, with an initial supply of both included. A supplied model eye supports optical performance checks, and the dust cover forms part of the stored equipment set. These items give routine upkeep a practical basis: clean optical surfaces, maintained patient supports, available paper and an identifiable reference for measurement checks.

A single integrated tabletop assembly

The display, measurement head, patient supports, joystick and printer belong to the instrument assembly. Its 491 × 312 mm depth and width describe the equipment footprint, while the 450 mm height and approximate 23 kg mass support room planning. A 100–240 V AC input supplies the unit, keeping its electrical specification separate from its physical positioning requirements.

Five measurement functions and ocular-surface observation

Objective refraction, keratometry, topography, tonometry, and pachymetry form the five measurement functions. The additional ocular-surface application supplies four included observation tools. This 5 + 1 arrangement gives the operator a defined group of examinations from which to select, with optical measurements, pressure values and surface observations available through the integrated control system.

Electrical measurement-cone exchange

Different measurement modes use the instrument's electrically exchanged cones. The mechanism completes the change in about 4 seconds, placing the next optical or pressure-measurement arrangement into position for its examination. Tomey's 90-second performance statement applies to the five-function measurement sequence. Ocular-surface recordings, including the 10-second blink assessment, have their own acquisition steps.

Automatic alignment and acquisition

Image recognition supports alignment of the measurement head with the eye. Once the alignment conditions are met, automatic acquisition can trigger the measurement; manual acquisition is also available through the controls. The moving head and motorised chin rest provide the physical positioning system, while the operator watches the eye and examination state on the colour touchscreen.

Objective refraction with selectable display steps

The refraction system analyses the form of an infrared ring image returned from the retina. It measures spherical power from −30.00 to +25.00 D and cylindrical power from 0.00 to ±12.50 D at a 12 mm vertex distance. Display increments are 0.01, 0.12, or 0.25 D, and the astigmatic axis spans 0–180° in 1° steps. The minimum pupil diameter for refraction is 2.0 mm.

Quick Ref acquisition

Within the refraction controls, Quick Ref provides a mode intended for interrupted fixation. Tomey identifies children and patients with nystagmus among its applications. The function supports the operator's choice of acquisition approach for the eye being examined, while retaining the instrument's objective sphere, cylinder and axis output for professional review.

Keratometric radius and axis measurement

Keratometry uses the reflection of an illuminated ring from the anterior corneal surface to calculate curvature. The radius range is 5.00–13.00 mm, displayed in 0.01 mm increments, and corneal astigmatic axis extends from 0 to 180° in 1° steps. These readings describe corneal curvature at the keratometric measurement area and complement the instrument's topographic surface maps.

Sixteen-ring anterior corneal topography

An illuminated pattern of 16 Mire rings provides the reflected image used for surface mapping. The topographic measurement area is 8 mm in diameter, with a stated curvature-radius range of 5.50–10.00 mm. Map presentation includes Fourier analysis for reviewing components of corneal shape. The radius display advances in 0.01 mm steps, and the axis display in 1° steps.

Air-puff tonometry

A controlled air puff changes the corneal shape while an optical detector monitors the response. The tonometry function measures intraocular pressure from 1 to 60 mmHg, with an alternative display range of 1–80 hPa. Individual results are displayed in 1 mmHg steps; averaged pressure values can be displayed in 0.1 mmHg steps. Tomey describes the air-puff delivery as gentle.

Central pachymetry and pressure adjustment

Oblique infrared illumination produces reflections from the anterior and posterior corneal surfaces. Their separation provides the central corneal thickness measurement, covering 300–800 micrometres with a 1-micrometre display increment. The pressure-adjustment function uses this thickness measurement to calculate an additional reference pressure. Central thickness and its display increment remain distinct from the calculated pressure value.

Pupil, corneal and interpupillary dimensions

Topographic acquisition also measures the pupil diameter and corneal white-to-white distance. Both diameter ranges extend from 1.00 to 14.00 mm, with 0.1 mm display steps and operator adjustment of the measurement points. Interpupillary distance spans 20–85 mm in 1 mm steps, adding the separation between the eyes to the recorded dimensional information.

Tear meniscus and conjunctival observation.n

Tear meniscus height gives the clinician a measurement related to tear volume and tear-film status. Conjunctival images allow assessment of visible redness and vessel appearance. Both functions belong to the included ocular-surface application, so these findings can accompany the optical measurements within the same examination session and remain available for review as part of the surface assessment.

Infrared Meibomian gland imaging

Infrared illumination records the appearance of the Meibomian glands for clinical inspection. The image supports review of gland structure during an ocular-surface assessment and sits alongside the instrument's other dry-eye observations. This imaging function is part of the standard application, giving the clinician a gland view to consider with tear meniscus height, conjunctival appearance,ce and blinking.

Ten-second blink assessment

A 10-second recording captures eyelid movement for assessment of blink frequency and quality. The timed sequence gives the observation a defined acquisition period, while the resulting analysis contributes a dynamic element to ocular-surface review. It complements the static meniscus, gland, and conjunctival images by describing the blinking activity recorded during that interval.

Optional TSAS tear-film stability software

TSAS evaluates changes in reflected Mire rings during continuous eye opening. Its integrated analysis follows distortion and blurring over time, generating ring break-up time and eye-opening time. Video and map displays provide views of the recorded changes, and export options support retention of the assessment. The software is an optional capability activated by a licence key.

Touchscreen, joystick and motorised chin rest

The 10.4-inch colour TFT-LCD touchscreen provides the main viewing and selection surface. A joystick supports movement and manual acquisition, while the motorised chin rest sets the patient support position. These controls bring observation, alignment and capture to the operator's working position, with the forehead and chin supports forming the patient-contact points.

Integrated storage, printing and file output

The internal database uses an integrated SD card, and the thermal printer produces results at the unit. Three USB 2.0 ports, one Ethernet connection and one SD-card slot provide physical data interfaces. DCM, XML, CSV, JPG and PDF are supported export formats. WLAN is a feature of wireless-equipped configurations, keeping the communication arrangement tied to the fitted hardware.

Surface care and optical reference checks

Daily care covers the measurement window, patient-contact supports, outer housing, and touchscreen, with different cleaning methods for these surfaces. The supplied model eye provides reference values for refraction, keratometry and topography checks. Replenishable chin-rest sheets and printer rolls support ongoing use, while the dust cover protects the instrument during storage between examinations.

The MR-6000 suits practices that want a seated pre-examination to connect refraction, corneal shape, central thickness, and eye pressure with ocular-surface observations. Its defining practical benefit is the electrically switched measurement sequence, supported by automatic alignment and controls kept at the operator's position. That combination fits a workflow in which several related findings are gathered before clinical interpretation. Routine use centres on clean optical and patient-contact surfaces, model-eye performance checks and replacement paper supplies. The optional TSAS licence gives an ocular-surface service a defined route to ring-based stability analysis. Across the standard functions, the patient remains at one instrument while the measurement cones exchange electrically in about 4 seconds.
