Description

UDR 800 Digital Refractor: Comfort, Precision, and Ergonomics for Eye Care Professionals

The UDR 800 by Unicos is a digital refraction system designed to meet the needs of practitioners seeking both user comfort and clinical performance. Its design is based on optimized ergonomics, featuring a compact body, intuitive control panel, and seamless connectivity with other Unicos devices—creating a streamlined and efficient working environment where every function serves a clear purpose.

Equipped with an 8-inch full-color touchscreen, the UDR 800 offers smooth interaction with its high-resolution graphic interface. Color-coded displays enhance data interpretation, while the GUI has been specifically designed for excellent readability, guiding users step-by-step throughout each stage of the visual examination. This user experience is further enriched by a central jog dial, which allows for easy selection of test parameters (SPH, CYL, AXIS, VA, PRISM, etc.), menu navigation, and data input.

The UDR 800 supports an extended measurement range, including spherical powers from -29.00 to +26.75 diopters, cylinders up to ±8.75D, and precise management of axis, prism, and pupillary distance. It is also equipped with retinoscopy lenses (+1.5D and +2.0D) and offers Jackson cross-cylinder testing options (+0.25D and +0.50D), while remaining compatible with standard auxiliary lenses (pinhole, red/green filters, polarized light, etc.).

In terms of connectivity, the UDR 800 fits perfectly into fully digital clinical environments. It communicates seamlessly with the URK-700 and URK-800 autorefractors, ACP-700 visual acuity chart projectors (Types A, B, C, and D), and the ULC-800 LCD chart projector. This wide compatibility ensures consistent data flow with no loss between devices and supports effortless integration into any exam management system.

Its sleek design and selected materials support hygienic use, with components treated to inhibit bacterial growth. Compact form factor, low operating noise, and practical keyboard shortcuts all contribute to efficient testing, even in limited spaces. The system also includes an integrated printing function and a USB port for software updates and maintenance.

With the UDR 800, Unicos offers a reliable and intuitive refraction solution that empowers eye care professionals with a complete, precise, and user-friendly tool for daily practice.
