Tono-Pen®, the one you trust in tonometry. 

Tono-Pen AVIA handheld tonometer requires no routine calibration and is always ready-to-use. An award winning ergonomic design, longer battery life, and enhanced IOP averaging technique, makes it the most advanced Tono-Pen yet. 

Routine calibration of Tono-Pen AVIA is not required. Spend less time worrying about your instruments and more time with your patients.   

With its award-winning, ergonomic design and soft-touch grips, the lightweight Tono-Pen AVIA fits comfortably in any operator’s hand, ensuring consistent measurement technique among users.  

To take a measurement, simply press the button once. When the light turns to green, Tono-Pen AVIA is ready to use. Gently tap the anesthetized cornea until a short beep sounds to alert the operator that the measurement is complete.  

Tono-Pen AVIA is less sensitive to corneal centration than other tonometers and provides fast, accurate, and repeatable results with minimal operator bias.

Only minimal training is necessary to become proficient in obtaining reliable IOP measurements.

Unlike most other tonometers, Tono-Pen can be used in any position, making it easy to measure all patients, including those who may be in a wheelchair or bedridden.

The IOP measurement is displayed on two large, easy-to-read, LCD screens making it suitable for both left and right handed users.

The convenient on-screen battery indicator ensures that Tono-Pen AVIA will always be ready for use. The removable Tono-Pen AVIA POWERCEL® battery pack is easily replaced, requiring no tools. Just squeeze and pull.
