1. Introduction
1.1. Outline of the Instrument
The HUVITZ Digital Refractor HDR-7000 system is a computerized auto refractor
used for subjective refraction by regarding the patient’s accommodation power and
facilities. Also the Digital Refractor is used for detecting and measuring any
anomalies in binocular vision such as muscle balance, binocular balance,
aniseikonia, fusion, and stereopsis. The subjective refraction can 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 aid of fully integrated and automated
Digital Refraction System where every instrument for the refraction is interfaced
and controlled by one touch of button on the Digital Refractor.
HDR-7000 system includes a refractor body, an operation panel, and a junction
box.
The refractor body has more than a hundred lenses and serves as an automatic
lens-loading unit. It is connected to the operation panel via the junction box and is
controlled by the operation panel.
The operation panel is the main controller of HDR-7000 system. It controls the
refractor body, chart-presenting device, and also receives data transmitted from
Auto Ref/Keratometer(RK), Auto Lensmeter(LM), or a PC interfaced with Digital
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
Operation Panel. And it provides communication ports for interfaced instruments
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, HDR-7000 system makes office environment more clean and
modest.
2. Because 1 or more(up to 8) HDR-7000 system and 1 or more(up to 4 each)
LM/RK are connected without any additional equipment, high utilization and
low cost can be achieved.
3. Compatibility between Huvitz products enables to manage patients’ 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, additional power data are
gathered automatically from LM. All of these data are presetting to the HDR-
7000 system without manual control.
4. HDR-7000 system supports near PD (48~80mm) and near working distance
(50~74cm), so you can execute perfect near vision tests.
5. Separated Dual Cross Cylinder lens and automatic occlusion during lens
change makes more accurate test result.
6. For accurate Phoria and Strabismus test, HDR-7000 system support prism
measurement by 0.1D unit up to 20D unit. Also automatic occlusion during
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, HDR-7000 system supports table and graphic
result display facilities.
9. Built-in high-speed printer saves additional space to install printer equipments
and prints test results extremely fast.
10. PRESET faculty defers physical lens change until all the necessary lenses are
ОсОО «МЕДОФФ» www.medoff.net

20 HDR-7000 Operator’s Manual ------------------------------------------------------------------
properly set at any states.
11. HDR-7000 system supports wide visual acuity up to 40’
12. Touch Screen supports various functions of the Operation Panel by using
touch-pen with ease.
13. Dialog-driven menu and simple function keys make it easy to access
complicated faculties. In addition, using [SHIFT] or [ALT] key combinations,
various options and faculties are easily accessed and executed.
14. To escape from the previous dialog as fast and convenient as possible, [ESC]
key is supported.
15. For professional examiners, 18 visual acuity tests, 24 monocular/binocular
balance tests, 35 user defined unit tests are supported. Also a Standard and 10
user-definable pre-programmed sequences are supported.
16. The CDR-MATE program running on a PC which supports PC-connectivity and
PC-style printer interface is optional.
17. Various binocular balance tests and phoria tests are supported. Advanced
graphical guide systems for such complicated tests are also available.
