DEVICE DESCRIPTION
The TONO-PEN AVIA VET tonometer is an ergonomic, hand-
held tonometer that measures intraocular pressure. The body
of the instrument is designed to t 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 applied force into an electrical signal.
The electronics housed in the ergonomic TONO-PEN AVIA VET
tonometer body process and analyze 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).
