A valuable addition to your practice


When taking care of patients, every minute is valuable. There is no time for dealing with 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.



How we can help

ZEISS VISUREF 100 – a straight­forward, easy-to-use diagnostic instrument provides accurate and reliable data for your daily practice routines.

Easy to set-up and use, the ZEISS VISUREF 100 can be operated after only a short training period. Intuitive handling features let you conduct the most important measurements with one device, including contact lens base curve, pupil and iris diameter evaluations. Refraction measurements of patients with implanted IOLs are also possible. Additionally, the automatic fogging incorporates an infinity scene to reduce the effects of accommodation.

As such, the ZEISS VISUREF 100 quickly becomes a valuable part of your practice environment, adding more precision and reliability to your vision care – right from the start.

Learn how you can improve working with ZEISS VISUREF 100.
