"The IOP measurements by Tonosafe disposable prisms correlated closely with Goldmann measurements, with similar repeated measurement variability to GAT. This suggests that the Tonosafe is an acceptable substitute for GAT to measure IOP in ophthalmology clinic settings."
V. Thomas et al. (2011), Eye

"We conclude that disposable prism tonometry provides a reliable, effective, and safe alternative to Goldmann tonometry with the advantages of eliminating the need for chemical disinfection and eliminating the risk of cross infection"
S. M Salvi et al. (2005), Eye

"The use of disposable prisms currently seems the most effective method of reducing cross contamination."

"This survey reveals disparity between current tonometer disinfection practice and published international recommendations, with some institutions using practices that may render patients susceptible to transmissible infection."

"The Tonojet was less hydrophilic than the Goldmann, and the contact angle of the fluid was therefore greater. For a given tear film, less hydrophilic tonometers will tend to have thicker mires, and this may lead to underestimation of the IOP."

"The range of variation between the Luneau SA disposable applanator and the Goldmann standard is sufficiently large to influence clinical management decisions."

"We recommend checking the GAT tips at the slit-lamp microscope on a regular basis and replacing those that show significant Damage."
