1. Introduction
1-1. Outline of product
DR13, Digital Reflector of MEDIZS, is enable subjective refraction test regarding
visual accommodation of patient’s eye or its function. Also, you can measure
and check abnormal binocular vision such as muscle balance of the eyes,
binocular balance, aniseikonia, fusion and stereo acuity. The subjective test is
based on measurement results of Auto Ref/Keratometer in communication with
DR 13. Optometrist could significantly reduce the time by tapping the control
of iPad Application which has auto functions of DR 13.
Basic components of DR 13 are Refractor body, iPad-App and junction box. In
the body of DR 13, there are more than 100 lenses. It could be operated by
Automatic lenses loader and controlled through iPad application to control DR
13 via Bluetooth wireless connectors.
This iPad application to control DR 13 could not only control refractor body
and chart projector, but receive the data from Ref/Keratometer(RK), Auto
LensMeter(LM), and refraction program on your PC. It also has functions to
send data by email and to print data (Printers only for iPad wireless printing).
Junction Box supplies DR 13 with power.
