Put infection where it belongs Tonosafe™ is a disposable measuring prism for all Goldmann Applanation Tonometers such as the AT 900 and the AT 900 D, as well as the Perkins Tonometer. Tonosafe™ disposable 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 it after each use.
