VISUREF 150 – autorefractor and keratometer


Autorefractor and Keratometer

VISUREF® 100 and 150 from ZEISS are basic diagnostic instruments that combine reliable performance with great user convenience. Each delivers fast, trustworthy refraction and keratometry results for an in-depth assessment of patient condition. Easy to set up and use, the ZEISS VISUREF 150 can be operated after only a short training period.

Intuitive and modern

Data management

Flexible instrument control

Intuitive user interface

Apart from refraction and keratometry the intuitive workflow-oriented user interface also conducts cornea and pupil diameter measurements, image capture and contact lens base curve measurements. Adaptable illumination parameters allow measurements of patients with implanted intraocular lenses (IOLs). The automatic fogging incorporates an infinity scene that reduces the effects of accommodation.

The intuitive user interface guides the user through the main workflow steps of the refractive assessment. Choose from different measurement settings (e.g. manual, auto trigger) and various illumination parameters (e.g. IOL mode) for optimal results.

Data management

Quickly retrieve previous measurements via the local device memory. View all details for up to 10 measurements per eye and their average values. Print out results with the integrated thermal printer or as a PDF file over a network printer. Review measurement data on a PC via the web server interface.

Flexible instrument control

Conducting measurements with the touch screen and joystick is very easy. Diagnostic information is displayed in excellent resolution on the adjustable color touch monitor. Patients are quickly and comfortably positioned with the motorized chin rest. The integrated quick release brake prevents unintended movements of the instrument base.
