Data Base
RET-700 offers an integrated patient database which stores multiple patient exams.
Compatibility & Connectivity
RET-700 can communicate with DR-900 Digital Refractor, where REF data can be exported to DR-900 automatically or manually. By one touch on the [Set] button on DR-900 touchscreen panel, objective data is instantly sent to the refractor head.
