Tono-Pen AVIA®

  • No Calibration
  • The TONO-PEN AVIA does not require daily calibration
  • Accurate and Easy to Use

The TONO-PEN AVIA is designed to help eliminate operator error and functions in any position, making it ideal to use on all 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.

The TONO-PEN AVIA utilizes micro strain gauge technology and a 1.0mm transducer tip. The device displays the average of 10 independent readings along with a statistical confidence indicator, ensuring accurate, repeatable, and reliable tonometry results.

The TONO-PEN AVIA tonometer 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. The proven reliability of Reichert’s applanation tonometers allows operators to take IOP measurements confidently anytime, anywhere, and in any position.

Tono-Pen® XL

Advanced Technology for Accuracy and Repeatability.

The Tono-Pen XL tonometer utilizes micro strain gage technology and a 1.0 mm transducer tip. Leading Edge recognition software ensures that measurements are taken only at applanation, while ScanLock tracking rapidly scans the electronic measurement data at a rate of 500 samples per second. This advanced microprocessor technology produces objective IOP measurements that are less influenced by operator bias than Goldmann tonometry. The average of four independent readings, combined with a statistical confidence index, ensure accurate, repeatable, and reliable tonometry results.

Easy to Use
The Tono-Pen XL tonometer functions in any orientation, making it ideal to use on all of your patients including those in beds or wheelchairs. The device activates with the push of a button and results are displayed clearly on the easy-to-read LCD screen. Patients will appreciate the quick and gentle measurement process.

  • Clinically Trusted
  • Clinicians worldwide have made the Tono-Pen XL tonometer a trusted part of their practice for nearly two decades. The proven reliability of the device allows operators to take IOP measurements confidently anytime, anywhere, and in any position.


  • 25 years of clinically proven accuracy and reliability

Perkins Mk3

Perkins Mk3 hand-held tonometer

  • New ergonomic design
  • Innovative LED illumination
  • ’Tonogrip’ prism holder
  • Integrated rechargeable batter
  • Tonosafe compatible
  • Clinically trusted accuracy

Established for over 30 years, Perkins is synonymous with being the “gold standard” in hand-held applanation tonometers.

The Perkins Mk3 hand-held applanation tonometer combines the same proven accuracy as the clinically trusted Perkins Mk2, but with an improved ergonomic design, longer lasting battery and excellent internal LED illumination.

Building upon the extreme portability of the Perkins Mk2 tonometer, the enhanced Mk3 is comfortable to hold, well-balanced and designed specifically to examine bed-ridden, wheelchair bound, paediatric and community-based patients, who have often been difficult to assess by traditional applanation tonometry methods.

The innovative built-in LED illumination produces an enhanced image of the tonometer mires, permitting use regardless of ambient lighting conditions. The LED source uses less energy and increases the operating times achieved from the integrated rechargeable battery as well as producing lower operating temperatures, giving greater comfort to both you, and your patient.

Prisms and ’Tonogrip’
Like previous Perkins and Goldmann tonometers, the Perkins Mk3 is compatible with reusable Goldmann tonometer prisms or Tonosafe disposable applanation prisms to minimise the risk of patient crosscontamination. In addition, the new easy-to-use ‘Tonogrip’ prism holder allows for straightforward placement of sterilised prisms.

Goldmann compatible
The Perkins tonometer has the unique ability to provide applanation tonometry readings that correlate strongly with Goldmann tonometer. The easy-to-use, lightweight and portable design of the Perkins Mk3 make this tonometer a confident, convenient and cost-effective measure of intraocular pressure (IOP)
