Nidek HandyRef K Handheld Refractometer
The HandyRef-K Portable 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.
Nidek HandyRef K Handheld Refractometer Keratometer 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) 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.
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.
