1. Main features of the refraction head
Vision-R
TM
700 (V01) is an automated phoropter that enables you to perform a refraction test. Its function is to
determine optical correction (or compensation), thereby providing examinees with optimal vision.
This part of the eye examination is commonly referred to as subjective refraction, because it refers to the
patient's responses. In the majority of cases it is performed using preliminary data which may come from:
The old correction performed using the lensmeter,
From a measurement of the objective refraction using an auto-refractometer, an aberrometer or a
skiascope/retinoscope,
The old correction archived in a patient file.
Since this is a so-called “automatic” head, its integration into the examination environment also includes
the control of the test projection systems from the same control panel.
The patient's subjective refraction is made possible by inserting an optical correction or a diopter compensation
and/or filters in front of the patient's eyes.
The measurements can be taken under monocular or binocular vision conditions and subsequently allow for a
binocular vision examination to be performed.
The instrument allows the user to carry out continuous variations of optical characteristics (sphere, cylinder, axis
and prism).
