Marco HandyRef-K Portable ARK
The HandyRef-K is a portable solution for accurate refraction and keratometry measurements anytime and anywhere. The HandyRef-K is lightweight and has excellent weight distribution. 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 patient’s anxiety and draw attention. Data can be transferred quickly and easily to PC.
SynchroScan Technology: The HandyRef-K uses “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.
Lightweight Design: The HandyRef-K is lightweight with excellent weight distribution. Its compact design makes it easy to hold, balance, and use with either hand.
Supine Position Mode: When tilting the instrument 60º or more downward, the supine position mode automatically starts. When measuring from the patient’s side, the cylinder axis is compensated by 90º, and is displayed.
3.5" Color Screen: New full graphic 3.5-inch color LCD is 40% larger than the previous model. Clear screen design and intuitive icons are user-friendly.
Pupil Imaging Method: The HandyRef-K analyzes a wide area (Max. 4 mm diameter) pupil zone, giving measurement data representing the refractive error of the patient’s system. Small pupils (Min. 2 mm diameter) can also be measured.
