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.
