EZER’s EDR-5400 will seamlessly adapt to your practice with no additional investment required, allowing you to perform all the functions that a manual refractor can do while comfortably seated next to your patient.  The EDR-5400 communicates with pre-test equipment and emr systems to upload patient data as a refraction starting point, as well as save refraction results. The intuitive keypad controller is small enough to place on any work surface and can also be operated from a standing position.  With the touch of a single key function, the EDR-5400 allows you to perform all refraction functions.
