Instructions for Use

Positioning

To obtain quick, easy, and accurate IOP results,
Tono-Vera Vet features the ActiView Positioning System to guide
users to proper alignment.
The default Measure Mode is ActiView Auto Measure which
enables automatic measurements upon correct alignment.
Canthus marks on the outside of the device also aid with
alignment.
Turn Tono-Vera Vet on by pressing any button.
1
Install a new Ocu-Dot Probe.
2
OD (right eye) will automatically be selected, indicated by
3
a blue circle.
NOTE: To start on the OS (left eye), press the button
beneath the OS area to select the left eye.
Position the device so that the two canthus marks located
4
at the front of Tono-Vera Vet (one on each side) are
level with the patient's canthus. Tono-Vera Vet is able to
measure at a probe angle of ±15º, but the Ocu-Dot Probe
must remain perpendicular to the eye.
The correct working distance is 6 mm (±2 mm) from
5
the eye.

Device Orientation

Tono-Vera Vet can be rotated a full 360º around the axis of
the Ocu-Dot Probe, as long as the probe is kept parallel to
the ground, within the ±15º probe angle range.
