Product Description:
Thank you for purchasing the Visionix Auto Refractometer VX 90.
The VX 90 is an autorefractometer and a keratometer,
The VX 90 is measuring the objective refraction of the eye giving sphere, cylinder and axis,
using an Infra-red ring projection on the Retina.
The keratometer measurement of radius of cornea is done in the same time with another
Infra red ring, by measuring the reflection of this ring on the cornea. 4 external fixation dot
allow the user to perform peripheral keratometry.
The Machine is showing the intra ocular lens potential opacity with the retro illumination
mode.
The practician could also measure the pupil diameter by moving 2 cursors on the screen, the
pupil diameter is then displayed on the screen.
A moving fixation target with auto fogging allows the patient to fully desaccomodate in
order to get the patient refraction in the best conditions.
Intended Use : The VX 90 is an ophthalmic diagnostic device, autorefractor, keratometer,
intended for
- Measuring the refraction of the eye, giving sphere, cylinder and axis
- Measuring the radius of the cornea, central and peripheral keratometry.
- Measuring the pupillary diameter
- Retro illumination for detection of the internal opacities.
Intended Users : the intended users are Opticians, Optometrists, and Ophthalmologists.
The data given by the VX 90 will be used by a qualified person as starting point to start the
subjective refraction to make the final prescription. The VX 90 only is not suitable to give the data
