Probe Angle (±15º)
Instructions for Use (continued)
Aligning
Using the ActiView Positioning System, slowly align Tono-Vera Vet so the device
is level with the eye.
NOTE: 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 Probe Angle Indicators
located on the left and right side of the positioning target will help with the
probe angle. The Probe Angle Indicators will be yellow if the probe angle is too
high or too low, and will be green when the probe is within the correct probe
angle range. The device will not measure if the probe is outside of the ±15º
probe angle range.
Using the ActiView Positioning System, slowly align Tono-Vera Vet so the device
is centered over the pupil and the Ocu-Dot Probe is approximately 6 mm from
the apex of the cornea.
A colored ring will appear when the device detects the eye. The size, color, and
position of the ring indicate alignment and distance.
The goal is to obtain a green ring directly over the central alignment target. This
indicates proper distance and proper alignment.
Yellow Ring
Device is too far away or off-center. Move closer or more centered on the eye.
Green Ring
Proper alignment and distance obtained.
Large Red Ring
Device is getting too close. Move the device further away from the eye.
Large Red Stop Sign
STOP! Device is too close. Move the device further away from the eye.
