Automated Refraction Measurement
The Matrix R20+ Auto Refractometer is designed for objective refractive assessment, with a refractive measurement range of +25D for sphere and +10D for cylinder, using selectable 0.12D or 0.25D steps.
Axis measurement is available from 1°–180° in 1° steps, while the system supports vertex-distance settings of 0, 12, 13.5 and 15 mm.
The auto-quick 3 mode provides an automated measurement workflow, while manual and IOL modes can be selected from the monitor according to the examination requirement.
Integrated Keratometry with KR-20+
The KR-20+ Autorefkeratometer extends the system’s functionality by incorporating keratometry measurement. It measures corneal curvature radius from 5.0–10 mm with 0.01 mm steps, along with corneal refractive power from 30.00D–67.00D.
Corneal astigmatism can be measured from 0–15.00D, with axis measurement from 1°–180°. Corneal size measurement ranges from 2–12 mm.
This makes the KR-20+ suitable for eye-care facilities looking for an autorefractor keratometer capable of combining objective refraction and corneal measurements.
High-Resolution Monitor & Thermal Printer
The Matrix system incorporates a 5.7-inch high-resolution colour LCD monitor for viewing measurement information and examination images.
A fast thermal printer with an easy paper-loading facility is integrated into the unit, allowing measurement results to be printed conveniently as part of the clinic workflow.
