Refractometer HandyRef - Excellent 2020

The HandyRef refractometer - Precise and reliable ocular refraction.

With its Pupil Zone Imaging method, it can analyze a wide pupil area, reaching a maximum diameter of 4 mm. This feature allows for even more precise measurements, approaching subjective refraction, which is essential for vision diagnosis and correction.

This refractometer is equipped with a Super Luminescent Diode (SLD) light source that provides a sharper and better-defined ring image compared to conventional LEDs. Additionally, the highly sensitive CCD camera detects the image even with low fundus reflection, ensuring accurate measurement in various clinical conditions.

A notable feature of this device is its SynchroScan technology, which starts measurements from the beginning of alignment and records data when optimal alignment is achieved. This approach ensures stable and efficient measurements.

The 3.5-inch color LCD graphical screen is 40% larger than previous models, providing a clear and user-friendly interface. Intuitive icons simplify usage, and it is also suitable for single-handed use.

In the lying position mode, tilting the instrument 60 degrees or more downwards automatically activates the lying position mode, adjusting the cylindrical axis by 90 degrees for more accurate reading.

The Auto Shot mode allows the refractometer to automatically capture measurement data when alignment and focus are optimal. In case of unstable data inclusion, additional measurements are automatically initiated.

The quick measurement mode offers a simplified option for patients with alignment difficulties or unstable eye movement.

In case unreliable data is obtained through the Auto Shot method, the additional measurement mode (AM) will automatically perform additional measurements.

Pupil size measurement is automatically performed during auto-refraction (AR) measurement, and settings can be adjusted to allow manual pupil size measurement if needed.

The HandyRef also stands out for its lightweight and compact design, facilitating handling and use. Removable magnetic eye shields cover the unmeasured eye to allow the other eye to focus on the target.

The refractometer has measurement data management, with the ability to store measurement data for 50 patients (100 eyes) in its internal memory. Additionally, a melody function is available to assist less experienced patients, such as children, by attracting their attention and reducing anxiety.
