The Gold Standard in tonometry

The AT 900 Goldmann tonometer comes in several different models with a comprehensive range of accessories. Each tonometer attaches to the slit lamp and pivots in front of the microscope for easy examination, with observation of the applanated surface conducted monocularly.

Disposable tonometer prisms (such as Tonosafe™) or resusable Goldmann measuring prisms can be used with all Haag-Streit tonometers.

Goldmann Applanation Tonometer

Because it is fast and reproducible, Goldmann applanation tonometry has been the gold standard in tonometry for many decades. Thanks to the high precision of manufacturing at Haag-Streit, the AT 900 offers reliable performance over many years without the need for manufacturer maintenance.

Reusable Goldmann prisms

Goldmann tonometer prisms are manufactured by Haag-Streit and are recognized as being an important part of a diagnostic instrument that has become the gold standard for IOP measurement.

Goldmann measuring prisms are distinguished by their optical and mechanical performance, which allows for fast and reliable measurements in daily practice. Reusable, they can be disinfected with a number of commercially available disinfectants.

Tonosafe™ disposable prisms

Tonosafe is a disposable measuring prism for all Goldmann Applanation Tonometers. Single-use Tonosafe tonometer prisms are a convenient, effective method of reducing the risk of cross-infection between patients.

Tonosafe is specifically designed for use with Goldmann Applanation Tonometers as the Tonosafe prism and holder combine to have the same dimensions as the original Goldmann prism and therefore no conversion of results is required.

With Tonosafe there is no need to disinfect the prisms after each patient. You simply dispose of them after each use.
