Premium vision starts with premium diagnostics


The ZEISS VISUREF 100 is a 2-in-1 diagnostic instrument, including an auto-refractometer and a keratometer.

  • Hightlights

    ZEISS VISUREF 100 provides accurate and reliable data for your daily practice routines. Intuitive features let you conduct the most important measurements with one device, including pupil and iris diameter evaluations. Refraction measurements of patients with implanted IOLs are also possible. Additionally, automatic fogging incorporates an infinity scene to reduce the effects of accommodation.

    A valuable addition to your practice

    When taking care of patients, every minute is valuable. There is no time to be wasted by complex systems. Still, you need diagnostic data that is reliable and accurate, no matter what--especially for the very first step in vision care, the refraction/keratometric evaluation.

    ZEISS VISUREF 100. Adding more precision and reliability to your vision care – right from the start.
