1. Introduction
1.1. Outline of the Instrument
The SHANGHAI HUVITZ Digital Refractor CDR-9000 system is a computerized
auto refractor used for subjective refraction by regarding the patient’s accom
modation power and facilities. Also the Digital Refractor is used for detecting
and measuring any anomalies in binocular vision such as muscle balance, bin
ocular balance, aniseikonia, fusion, and stereopsis. The subjective refraction ca
n be practiced on the basis of objective refraction that is done by using an
Auto Ref/Keratometer(RK) connected to Digital Refractor. The examiner can do
their optometric practice in pretty short period of time with ease with the ai
d of fully integrated and automated Digital Refraction System where every ins
trument for the refraction is interfaced and controlled by one touch of button
on the Digital Refractor.
CDR-9000 system includes a refractor body, an operation panel, and a junctio
n box.
The refractor body has more than a hundred lenses and serves as an automa
tic lens-loading unit. It is connected to the operation panel via the junction b
ox and is controlled by the operation panel.
The operation panel is the main controller of CDR-9000 system. It controls th
e refractor body, chart-presenting device, and also receives data transmitted fr
om Auto Ref/Keratometer(RK), Auto Lensmeter(LM), or a PC interfaced with Di
gital Refraction System. And also it has a built-in thermal printer with it.
The junction box serves as a power supply to the Digital Refractor and the O
peration Panel. And it provides communication ports for interfaced instrument
s such as Chart Projector or Auto Ref/Keratometer.

3. Features
1. Using standard protocol CAN, all appliances are connected by daisy-chain
line. As a result, CDR-9000 system makes office environment more clean a
nd modest.
2. Because 1 or more(up to 8) CDR-9000 system and 1 or more(up to 4 eac
h) LM/RK are connected without any additional equipment, high utilization
and low cost can be achieved.
3. Compatibility between SHANGHAI HUVITZ products enables to manage pa
tients’ data more easily. For example, not only S/C/A value but also KER,
PD data are gathered automatically from RK. Also S/C/A value, prism, add
itional power data are gathered automatically from LM. All of these data
are presetting to the CDR-9000 system without manual control.
4. CDR-9000 system supports near PD (48~80mm) and near working distanc
e (50~74cm), so you can execute perfect near vision tests.
5. Separated Dual Cross Cylinder lens and automatic occlusion during lens c
hange makes more accurate test result.
6. For accurate Phoria and Strabismus test, CDR-9000 system support prism
measurement by 0.1D unit up to 20D unit. Also automatic occlusion durin
g prism change minimizes the examinee’s eye adaptation.
7. On-line guide assist examiners to finish test fast and convenient.
8. To analyze result at a glance, CDR-9000 system supports table and graphi
c result display facilities.
