VISUREF® 150 from ZEISS is a basic professional instrument that combines reliable performance with great user convenience. It delivers fast, reliable, objective 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 a short training period.
The ZEISS VISUREF 150 Autorefractometer and Keratometer is designed for eye care professionals who need fast, accurate, and consistent refraction and keratometry measurements in busy clinical environments. In daily practice, delays in patient flow, inconsistent readings, and complex device handling can reduce efficiency. The VISUREF 150 solves these challenges with intuitive operation, automatic measurement modes, and reliable ZEISS optics. It combines objective refraction and precise corneal curvature measurement into a single compact unit, making it an ideal solution for clinics and hospitals focused on speed, accuracy, and workflow optimization.
