Disposable tonometer prisms
Tonosafe™ is a disposable measuring prism for all Goldmann applanation tonometers as well as the Perkins tonometer. Tonosafe™ disposable prisms are a convenient, effective method of reducing the risk of cross infection between patients.
Excellent optical quality
The reusable Goldmann measuring prisms are distinguished by their optical and mechanical performance which allows for fast and reliable measurements in daily practice. They are largely handmade by experienced workers, and are checked for tight tolerances in weight, optical quality, durability and for consistent measurement results.
Simple and safe disinfection of reusable prisms
For efficient disinfecting routines we recommend Haag-Streit Desinset. This instrument set is ideal for disinfection of reusable tonometer measuring prisms and comprises cleaning- and storage container.
Because it is fast and reproducible, Goldmann applanation tonometry has been the gold standard in tonometry for many decades. It is based on the Goldmann principle – tried and tested
during more than 50 years of usage with millions of patients.
Furthermore, thanks to the high precision of manufacturing at
Haag-Streit, the Goldmann applanation tonometer offers reliable
performance over many years without the need for manufacturer maintenance.
AT 900 is the original version of the Goldmann tonometer and
works 100% mechanically. The digital Goldmann tonometer
AT 900 D* adds the advantages of state-of-the-art digital technology.
