FKR-8900 autoref-keratometer with advanced image processing and humanised auxiliary focusing — the next-generation ARK for refractive-surgery centres and contact-lens specialists.
Clinical overview
The OpticsMED FKR-8900 is the next-generation auto refractometer-keratometer with advanced image-processing technology that delivers clearer measurement images at a faster speed than older platforms. The humanised auxiliary focusing function speeds up the technician's targeting step, and the integrated ARK design covers both refraction and corneal curvature in a single chinrest sequence.

| Cylinder | -8.00 to +8.00 D |
| Axis | 1° – 180° |
| PD | 45 – 85 mm |
| Corneal diopter | 33 – 67 D |
| Corneal astigmatism | 0 – 15 D |
| Corneal diameter | 2 – 12 mm |
| Power | AC 100 – 110V/240V, 50/60 Hz |
| Dimensions / weight | 275 × 475 × 435 mm / 18 kg |
Refractive-surgery pre-op clinics and contact-lens specialist practices where pre-test speed determines daily patient throughput. The humanised auxiliary focusing is the throughput differentiator over older ARK models.

Ordered this to replace an ageing unit and so far setup was straightforward with clear documentation. The value at this price point is hard to beat. No complaints so far.
Wei Nilsson, Optometric TechnicianVerified buyerSep 25, 2025
We've been using this in our exam room for a few weeks now and setup was straightforward with clear documentation. The value at this price point is hard to beat. A dependable choice for any exam room.
Lucy Clarke, OD, FAAOVerified buyerJan 19, 2025
We've been using this in our practice for a few weeks now and it feels solid and properly engineered. The build quality is genuinely reassuring. Does precisely what we needed.

The FA-8000K is a premium auto refractometer / keratometer with a 9-inch TFT LCD, motorised joystick, auto-tracing and auto-focus controls, integrated keratometer and hexagon-prism optics with a sensitive CCD. The tilting screen keeps the operator's neck neutral across long refraction sessions, while configurable vertex distances and a wide sphere and cylinder range support both adult and paediatric refraction. Designed for the high-end refraction room where speed, comfort and repeatability matter together. A premium combination unit for high-volume optometry and ophthalmology lanes.

The FA-6500K is positioned as an economical auto refractometer/keratometer combining objective refraction and corneal curvature measurement in a single workflow. A 7-inch tiltable TFT touch screen lets technicians angle the display for comfortable operation when working at the patient. The combined refraction + keratometry design is well suited to optometry practices fitting contact lenses or running high-volume routine exams. A budget-friendly desktop option for clinics consolidating pre-test on one device.

The FA-100K is a top-tier auto refractometer / keratometer that combines hexagon-prism optics with a CCD sensor and a 10.4-inch tilting touch screen. Fully automatic operation — auto eye-finding, auto measurement, and automatic transition between right and left eye — keeps refraction lane throughput high with minimal operator intervention. 3D auto-tracking maintains alignment through small patient movement. Designed for high-volume optometry chairs and specialty refraction lanes that want a hands-off refraction and keratometry workflow.

The RK-8000 is a combined auto refractometer and keratometer for routine refraction and corneal curvature measurement. It uses Hartmann Wavefront technology with split-image auto focus, and provides sphere, cylinder, axis, PD, and corneal radius readings on a 9-inch TFT LCD with built-in thermal printer. USB and RS232 interfaces support EMR and lensmeter integration. The device is intended for optometrists, opticians, and ophthalmologists in optical retail refraction rooms and general eye clinics.

The KR-9600 is a desktop auto refractometer/keratometer combining objective refraction and corneal curvature measurement in a single workflow. Running both tests on one device cuts patient handling time during pre-test and supports contact-lens fitting where K-values are required. The desktop format suits optometry practices and eye clinics looking for a consolidated pre-test station. A practical choice for offices that want refraction and keratometry on one instrument.

HRK-7000A premium autoref-keratometer with K/R + CLBC + KER P + peripheral keratometry — built for refractive surgery and irregular-cornea specialist clinics.

ARK-1 CE-certified Hartmann autoref-keratometer with 10.4" touchscreen, WiFi/Bluetooth/VGA data output — the connectivity-first ARK with the broadest measurement range in the line.
