AIN FEATURES OF THE REFRACTION HEAD
Vision-R TM 800 (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
conditions.
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 focimeter,
• From a measurement of the objective refraction using an auto--refractometer, an aberrometer or a
skiascope/retinoscope,
• The old correction archived in an patient file,
The results obtained from the patient’s responses allow the expert to determine the refraction and prescribe
the optical compensation (or another form of assistance) required for the patient’s good vision.
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 intercalating an optical correction or a diopter
compensation and/or filters in front of the patient’s eyes.
It allows measurements to be taken under monocular or binocular vision conditions and allows the binocular
vision examination to be performed.
The instrument allows the user to carry out continuous variations of optical characteristics (sphere, cylinder,
stem, prism).
