    What you face every day

    In order for any practice to run smoothly, routine assessments must be easy to perform. As part of the daily pretest workflow, the refraction assessment is no exception. Maintaining a high patient throughput in this area is key to the success of every eye care facility.

    How we can help

    VISUREF® 150 from ZEISS is a basic diagnostic instrument that combines consistent performance and user convenience. It delivers fast, reliable refraction and keratometry results for an in-depth assessment of the patient's condition. Easy to set up and use, the ZEISS VISUREF 150 can be operated after only a short training period.

    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 also allow measurements of patients with implanted intraocular lenses (IOLs). Additionally, the automatic fogging incorporates an infinity scene that reduces the effects of accommodation.

    The ZEISS VISUREF 150 has all the qualities needed to quickly become a valuable asset for your practice environment. Its modern communication technology allows the device to seamlessly fit into any practice, supporting efficient diagnostic workflows.

    Modern operating concept

    Modern operating concept

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

    Flexible instrument control

    Flexible instrument control

    Measurements are conducted easily using the touchscreen and joystick. Diagnostic information is displayed clearly on the adjustable color touch monitor. Leveraging the motorized chin rest allows patients to be quickly and comfortably positioned. Additionally, the integrated quick release brake prevents unintended movements of the instrument base.

    Data management

    Data management

    Previous measurements are easily retrievable via the local device memory. Users can view all details for up to 10 measurements per eye and their average values. Results may be printed out using the integrated thermal printer or through a network printer. Measurement data may also be reviewed on a PC via the web server interface.

    Versatile connectivity options

    Versatile connectivity options

    Connect the device to your EMR/PMS or to FORUM® from ZEISS. Import patient work lists with an iPad® or PC onto the ZEISS VISUREF 150 and directly select patients for measurement. Transfer data in common file formats (e.g. PDF, XML) to a USB stick or to a local network folder, and access data via a local web server. Export objective refraction data to the ZEISS acuity chart system to preset the VISUPHOR® 500 digital phoropter from ZEISS.
