In eye care, digital diagnosis and therapy systems play an important role. More than 400 different types of equipments with digital output are registered and more than 980,000 systems and instruments are installed worldwide. These devices range from autorefractors to highly sophisticated laser diagnostic devices (RT, OCT etc.). To connect these instruments with innovative electronic medical records (EMR), open standards are required.

With IHE (Integrating the Healthcare Enterprise) a platform for evaluating standards (like HL7 and DICOM) has been established.
