The Tono-Pen has been around for quite some time and like most staple handheld devices it hasn’t seen much change since its inception. Three different companies have since owned the rights to the Tono-Pen and now with Reichert strongly at the helm their successor is still a Tono-Pen, with basically much of the same technology, with basically the same name, and yet a different shape. It’s true that the AVIA’s transducer is slightly different and less intrusive, and it is true that it’s slightly more accurate, but I think with all that being said you buy the Tono-pen AVIA solely based on its newly designed shape. It’s a shape that sits in the operator’s hand far better than any other handheld tonometer and it somehow seems to defy gravity even at uncomfortable positions. Pictures; even ours- don’t do its curvature justice and the petite structure of the unit makes it incredibly portable and easy-to-use. Still, the AVIA is still very much the Tono-Pen of the past- and your patients won’t notice the boost in comfort for the operator seeming that a metal tip is still pressing down onto their cornea.
OUR TAKE: Much more ergonomic and comfortable than Tono-Pens of the past, still with a requirement for drops and contact.
Tono-Pen AVIA is designed to help eliminate operator error and functions in any position, making it ideal for use with all of your patients, including those in beds or wheelchairs. Activated by the push of a button, the IOP measurement is displayed on two large, easy-to-read LCD screens. Patients will appreciate the quick and gentle measurement process.
With its contemporary, award winning, ergonomic design, Tono-Pen AVIA is a very versatile addition to your practice. The LCD screens are positioned on either side of the Tono-Pen AVIA so both left and right handed users can visualize the measurement. The over molded grip zones help stabilize the Tono-Pen AVIA in virtually all hand sizes. Tono-Pen AVIA is extremely portable and comfortable to hold, making it easy to take IOP measurements anywhere, on any patient.
Tono-Pen AVIA features the same proven accuracy as the clinically trusted Tono-Pen XL, but with a more ergonomic design, four times longer lasting battery and larger LCD screens. Furthermore, the need for daily calibration has been eliminated, simplifying the measurement process. The proven reliability of Reichert’s applanation tonometers allows operators to take IOP measurements confidently anytime, anywhere, and in any position.
Tono-Pen AVIA utilizes micro strain gauge technology and a 1.0 mm diameter transducer tip. The advanced microprocessor technology produces objective IOP measurements that are less influenced by operator bias than Goldmann tonometry. The average of 10 independent readings, combined with a statistical confidence index, ensures accurate, repeatable, and reliable tonometry results.
Typically not, however calibration is occasionally required and a startup error will indicate that a calibration is required. Thankfully however, calibration is simple and can be performed in seconds via the operator.
The thick plastic/latex tip covers are simple to unpackaged and place on the transducer tip. Make sure the transducer tip cover is not on ‘too tight’ or ‘too loose’.
The AVIA, as it stands currently, has no EHR/EMR or networking capabilities. It is designed to be used as a standalone instrument only.
It sure does. Although Reichert advertised a less invasive measurement than the Tono-Pen XL, corneal numbing is required.
