Haag-Streit AT900 Goldmann Applanation Tonometer

The gold standard in IOP measurement

Because it is fast and reproducible, Goldmann applanation tonometry has been the gold standard of tonometry for many decades 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 manufacturer maintenance.
