Clement Clarke has developed a low cost disposable prism, which does not compromise the performance of Goldmann Applanation Tonometers. Tonosafe is developed, manufactured and supported by Haag-Streit, so quality, accuracy and reliability are assured.


  • Increased Patient Safety – Developed for single patient use. Tonosafe™ eliminates the risk of cross-infection
  • Easy to Use – The Tonosafe™ prism and holder combine to have the same mass as the Goldmann prism, so no conversion of results is required
  • Make You More Efficient – It only takes a moment to position the prism, and the optical clarity provides a superb view of the florescent semi-circles
  • Extreme Accuracy – Calibrated to Goldmann standards, Tonosafe™ is acceptable for use in all Goldmann and Perkins type tonometers
  • Reduces Risk of Costly and Stressful Litigation
  • Clinically Validated by Many Papers – Salvi et al. (2004) reports that it may be used for screening plus routine clinical use
