The Gold Standard

Because it is fast and reproducible, Goldmann applanation to-nometry has been the gold standard of tonometry for many de-cades until today. It is based on the Goldmann principle – proven 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 during many years without the need for manufac-turer maintenance.

Excellent optical quality

870 tonometer

Goldmann measuring prisms distinguish themselves by their optical and mechanical performance which allows for fast and reliable measurements in daily practice. They are largely handmade by experienced workers and checked for low tolerances in weight, optical quality, durability and for con-sistent measurement results.
