Objective Refraction and Corneal Curvature in One Unit
The ARK-710 auto refractor keratometer combines objective refractive measurement and corneal-curvature measurement in a tabletop instrument. Its documented K&R, REF and KRT modes let the operator select a combined workflow or an individual measurement mode according to the examination sequence. Results are measurement outputs for professional review and should not be presented as a diagnosis or treatment recommendation.
Documented Measurement Modes
- K&R mode: diopter and corneal-curvature measurement.
- REF mode: diopter measurement.
- KRT mode: corneal-curvature measurement.
The current ARK-710 brochure lists vertex-distance settings of 0, 12.0, 13.75 and 15.00 mm. The documented spherical range is -25.00 D to +25.00 D, the cylindrical range is -10.00 D to +10.00 D and the astigmatic-axis range is 0°–180°. PD is listed from 10 to 85 mm, with a minimum pupil diameter of 2.0 mm.
Corneal Measurement Scope
For the keratometry workflow, the brochure lists a corneal-curvature radius of 5–10 mm, a corneal astigmatic-axis range of 0°–180° and a corneal-diameter range of 2–12 mm. These ranges describe the documented instrument scope; they are not accuracy, repeatability or clinical-outcome claims.
Display, Alignment and Data Handling
Automatic eye tracking supports alignment during measurement. The 9-inch touch LCD can rotate through 360°, helping the operator position the control surface for different room layouts. The brochure also identifies Bluetooth communication, automatic printing and automatic paper cutting. Confirm the receiving-system requirements and permitted data workflow for the destination market before quotation.
Installation and Quotation Checks
The listed power requirement is AC 220 V, 50 Hz, 75 VA. The documented unit dimensions are 300(W) × 450(D) × 500–530(H) mm and the listed weight is 20 kg. Before ordering, confirm the destination electrical standard, included printer supplies, cables, accessories, language, workstation arrangement, documentation and service scope. Items not explicitly listed in the current brochure should be treated as quotation-dependent.
ARK-710 Frequently Asked Questions
Does ARK-710 measure both refraction and corneal curvature?
Yes. The brochure lists K&R for combined measurement, REF for diopter measurement and KRT for corneal-curvature measurement.
What display does it use?
The documented configuration uses a 9-inch touch LCD that can rotate through 360°.
Is ARK-710 a handheld autorefractor?
No. The supplied material presents it as a tabletop auto refractor keratometer.
Review more optometry and refraction equipment, or contact ENOCHTEC to confirm the ARK-710 configuration for your market.
