Nidek HandyRef-K and HandyRef Handheld Refractometer，The Marco HandyRef-K Portable ARK is a solution for accurate refraction and keratometry measurements anytime and anywhere. The HandyRef-K handheld autorefractor and keratometer is lightweight, and its compact design makes it easy to hold, balance, and use. The intelligently designed button layout is also useful in one-handed operation. For inexperienced patients like children, the newly added melody function can ease anxiety and draw attention. Data can be transferred quickly and easily to a PC.

Pupil Zone Imaging Method
The HandyRef-K analyzes a wide area pupil zone (max. 4mm diameter). More accurate measurement data, closer to the subjective refraction is possible by measuring the light coming through the pupil zone in a wider area. Small pupils (min. 2mm diameter) can also be measured.
Super Luminescent Diode (SLD) & Highly Sensitive CCD
Super luminescent diode (SLD) light source provides a sharper and more defined ring image compared to conventional LED. The highly sensitive CCD camera detects the image even if the fundus reflection is weak due to media opacities.
SynchroScan Technology
Measurements start when alignment is achieved, and data is captured when alignment becomes optimal. This provides a more stable, effective, and efficient measurement.
Measurement Modes
Auto Shot Mode – When the alignment/focusing becomes optimal, the HandyRef-K gets the measurement data automatically. If unstable data is included, additional measurement automatically starts.
Cataract Measurement Mode – If appropriate data cannot be obtained by standard measurement, it enters the cataract measurement mode automatically to harvest the data more easily.
Quick Measurement Mode – Faster and simpler measurement for patients who have difficulty in alignment. By relaxing the measurement range, children or patients whose eye movement is not stable can still be measured smoothly.
Additional Measurement Mode – If the measurement data obtained by auto shot is not reliable, additional measurement will automatically be performed by additional measurement (AM) mode.
Memory Data Management
The measurement data of 50 patients (100 eyes) is saved in the main body memory.
Melody Function
A melody can be played to hold a child’s attention during measurement.
Portable Base Unit & Printer
By utilizing a portable stand, the HandyRef-K can be used as a desktop device. An integrated printer with auto cutter function is also available. By using an IR or wireless LAN (WLAN) connection, measurement data can be printed even if the main body and station are separated.
