Two perfect prisms
Two Haag-Streit approved solutions: Tonosafe as a convenient and effective answer to the risk of cross infection and the reusable Goldmann prisms which provide superb optical and mechanical qualities.
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.
Convenient – safe – accurate
Tonosafe™ avoids the need for time-consuming and laborious disinfection without compromising the original Goldmann quality. Developed for single use only, it reliably eliminates the risk of cross infection even in the most difficult situations. Calibrated to Goldmann standards, Tonosafe™ delivers accurate results with all Goldmann and Perkins contact tonometers.
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.
Goldmann tonometer prisms are manufactured at Haag-Streit in a process that has been fine-tuned over years. Experience, professional workmanship and intensive quality checks ensure highest precision for this important part of a diagnostic instrument that has become the gold standard for IOP measurement.
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.
