Refraction should be fast and intuitive; the Refractor 900 delivers both. As a digital phoropter, it minimizes the manual adjustments required by traditional devices, allowing you to shorten exam times. Ultra-fast (120ms) lens changes and an innovative transparent lens carrier help reduce patient eye accommodation. For a quick determination of astigmatism, the Refractor 900 is equipped with a cross-cylinder function with Stokes technology. The result is a more efficient refraction that benefits both practitioners and patients.
