Introduction (continued)
Device Description
The Tono-Pen AVIA Vet tonometer is an ergonomic, hand-held to-
nometer that measures intraocular pressure. The body of the instru-
ment is designed to fit comfortably in the user’s hand, facilitating
fast and accurate measurements. The tip of the tonometer contains
a sensor that houses a transducer assembly which converts ap-
plied force into an electrical signal. The electronics housed in the
ergonomic Tono-Pen AVIA Vet tonometer body process and ana-
lyze the waveforms produced by each applanation of the corneal
surface of the eye. These are used to produce an averaged IOP
measurement. The measurement is displayed on the Liquid Crystal
Displays (LCDs).
A replaceable battery compartment houses the Tono-Pen AVIA Vet
POWERCEL®battery pack, consisting of two Lithium Manganese
Dioxide batteries.
Features
The Tono-Pen AVIA Vet tonometer has the following features:
• Easy to use - IOP can be measured reliably by veterinary profes-
sionals.
• Portable - The Tono-Pen AVIA Vet tonometer weighs just
71 g (2.4 oz) and is battery operated.
• Accurate - The measurements from the Tono-Pen AVIA Vet to-
nometer correlate strongly with Goldmann applanation tonometry
and direct measurements of IOP.
• Versatile - The Tono-Pen AVIA Vet tonometer may be used easily
with the patient in any position, making the instrument suitable
for the office and in remote locations.
