Which auto refractors are listed in Nigeria?

The current Franance listing has two Topcon models in this leaf: the KR-800 Auto Kerato-Refractometer and KR-1 Fully-Automated Kerato-Refractometer. Browse the full auto refractor listing for the assigned models, or the broader ophthalmology equipment category for related eye-care equipment.

Topcon calls both devices kerato-refractometers: they measure refractive power and corneal curvature. The KR-800 product page highlights a joystick and 8.5-inch colour touchscreen. Topcon describes KR-1 as fully automated with a control panel that rotates through 360 degrees. Its product page highlights touchscreen operation, a space-saving layout and USB or LAN data export. The category contains exactly those two current product records, so do not assume other products in Topcon’s broader international range are part of this Franance selection.

What does a kerato-refractometer measure?

An auto refractor provides objective measurements of refractive power. A kerato-refractometer also measures corneal curvature. For the two listed Topcon models, manufacturer specifications include spherical and cylindrical refractive power, astigmatic axis, corneal curvature radius, corneal refractive power and corneal astigmatic values. Topcon lists the KR-800 pupil minimum as 2 mm, and lists that same minimum for the KR-1. Such specifications describe the instrument’s measurement capabilities; they do not establish that a reading can be obtained in every patient or that it replaces a complete eye examination.

A clinic should have its optometrist or ophthalmologist define how the instrument fits the pre-test or refraction workflow. Ask which measurements must be available, what range is needed for the service, how operators position patients, and how results are reviewed with other examination findings. Do not purchase solely on a general “auto refractor” label if corneal curvature is required, or infer that keratometry alone provides every measurement needed for contact-lens fitting or specialist evaluation.

Model specifications use different display increments for some measurements, including refraction and corneal powers. These are technical details to compare against your service’s requirement, not patient-care instructions. Follow the instrument’s current instructions for use and the clinic’s approved protocols.

How do the KR-800 and KR-1 differ?

The KR-800 is described by Topcon as a compact, easy-to-use auto kerato-refractometer with Rotary Prism measurement, an 8.5-inch colour touchscreen and joystick. KR-1 is a fully automated kerato-refractometer featuring Rotary Prism technology, a 360-degree rotatable touchscreen and USB or LAN export. The manufacturer presents KR-1 as allowing multiple exam-room layouts through its rotating panel. Compare the actual operator interaction and intended workflow in a product demonstration if available.

The published KR-800 specifications include a spherical refractive-power range from -25 D to +22 D, cylindrical power from 0 D to +10 D, an astigmatic axis of 0 to 180 degrees, a pupil minimum of 2 mm and a corneal radius range from 5.00 to 10.00 mm. Topcon’s KR-1 page reports spherical power from -25 D to +22 D, a 2 mm minimum pupil and a corneal radius range from 5.00 to 10.00 mm. Manufacturer pages may be revised or vary by region; verify the current specification sheet for the exact unit before comparing these figures or placing an order.

Topcon lists KR-800 at 15 kg with 100–240 V AC, 50–60 Hz and 30–70 VA. KR-1 is listed at 19 kg with 100–240 V AC, 50–60 Hz and 75 VA. Confirm the exact dimensions, shipping weight, electrical connector and accessory set against the offered regional variant. These differences may affect bench planning and room placement, but do not determine which instrument is clinically appropriate.

Which model suits a clinic’s examination room and workflow?

Start from the clinical service specification and operator workflow. Consider how many examination lanes will use the instrument, the intended patient flow, who will position the patient and who will review results. If the clinic needs manual joystick-assisted operation, examine the KR-800’s manufacturer-described control arrangement. If a rotatable display and fully automated operation match the planned workflow, evaluate the KR-1. A product feature should be judged with the clinicians who will use it rather than inferred to improve throughput or clinical outcomes.

Measure the space available on the examination table or stand and the working distance around the patient. Compare the instrument body dimensions, chin-rest and forehead-rest access, operator sightline, display orientation, stool position, patient approach and cleaning access with the actual room layout. Topcon emphasizes compact dimensions for KR-800 and a rotatable control panel for KR-1, but the clinic should verify that either unit fits the specific lane and furniture.

Consider whether the auto refractor will be a standalone pre-test device or part of a connected exam lane. Topcon’s product family includes other systems and offers a digital exam lane concept, but neither fact means the required companion equipment, software or integration is included in these standalone catalogue listings. List each device, mount, chair, table, phoropter, chart and computer that the clinic expects to connect, then request confirmation of compatibility and package boundaries.

How should I plan USB, LAN and patient data integration?

Both current manufacturer pages describe USB and LAN data export; the KR-800 specification also lists RS-232C export, while KR-1 lists USB import, RS-232C export and LAN export. The exact connector directions and supported data workflow matter. A port listing does not establish interoperability with a named electronic medical record (EMR), hospital information system, optical practice system, printer or software version.

Ask the clinic’s IT team to name the target system, required data fields, destination workstation, network arrangement, security policy and record-matching workflow. Request Topcon or the supplier to confirm supported interfaces, export format, software requirements, licensing, cabling and any additional adapter or workstation. If the device is intended to operate standalone, specify whether local storage, printing or manual transfer is required and confirm what the offered configuration supports.

Do not assume that a USB connection imports or exports the same way as LAN or RS-232C. Request a system diagram and the exact interface specification for the offered model. Ask who is responsible for configuration, testing and user training, and whether an interface demonstration can be included in commissioning. Do not put identifiable patient data in a procurement test unless the clinic’s information-governance process permits it.

What space, power and installation details should I verify?

The KR-800 page reports dimensions of 317–341 mm wide, 521–538 mm deep and 447–477 mm high, a weight of 15 kg, and 100–240 V AC, 50–60 Hz, 30–70 VA. The KR-1 page reports 19 kg and 100–240 V AC, 50–60 Hz, 75 VA; its dimension text on the page appears to contain a width-unit formatting error, so use the current manufacturer data sheet rather than copying that dimension as printed. Confirm dimensions, weight, operating clearances and table or stand requirements before purchase.

For a Nigerian site, have facilities or electrical staff confirm the actual power connection, voltage range, frequency, plug, grounding and backup supply against the offered variant and instructions. While the published power ranges appear to cover common supply frequencies, this does not confirm the included plug, adapter, accessory package or suitability of the clinic’s backup system. Ask the quote to specify these details.

Plan delivery access, installation location, staff access and a stable, suitable surface. Request the installation and commissioning scope and ask whether the supplier will verify operation, configure any data output and provide a handover. If the instrument is part of a larger exam lane, have the whole room arrangement reviewed so patient and staff movement, cable routing and equipment sightlines work together.

What should I include in a Topcon auto refractor quotation request?

Tell Franance the intended model or requirement, whether refractive and corneal-curvature measurements are needed, room layout, operator workflow, data interface, computer or EMR destination, quantity, delivery address, city and state. Include the model of any existing Topcon or third-party equipment with which the unit must connect. If you are evaluating both models, ask for a side-by-side offer and demonstration or technical review.

Request an itemized quotation naming KR-800 or KR-1 and the exact manufacturer reference, regional variant, technical specification, included stand or table, chin-rest consumables, printer or other accessories if required, interface components, software or licenses, manuals, installation, configuration, training, warranty and service terms. Ask Franance to state price, availability and delivery assumptions for your Nigerian destination. The catalogue does not show an online purchase price or confirm that a device is in stock.

Ask for the model’s current instructions for use and confirm which measurements, connections and accessories apply to the actual offer. Have clinical staff approve the requirement, IT review the data flow and facilities staff check the site. Request a Topcon auto refractor quotation from Franance.
