Goldmann Reusable Tonometer Prism Facts
Examples of Real-Life Damaged Prisms
Regularly Carry Out a Prism Audit
>
>
Goldmann prisms should not remain in circulation longer than the recommended two year period of use. The Goldmann tonometer prism instruction leaflet states, “Before each use the contact surface of the prism should be verified for contamination or damage (such as scratching, rips or sharp edges).”
Hospitals are Failing to Regularly Audit their Goldmann Prisms In a recent in-house study, Haag-Streit surveyed 134 prisms from 22 different hospitals. >
The prism age range was between 0-32 years
>
86% were over two years old
>
The mean unit age was calculated at 9.8 years
>
52% were damaged
Recommended Lifespan of a Goldmann Prism = 2 Years
Hospitals are Failing to Carry Out the Recommended Disinfection and Sterilization Protocol Hospitals are not following the recommended disinfection and sterilization protocol, as outlined in the Goldmann tonometer prism instruction leaflet.
Best Practice Prism Check: Below are some examples of damaged prisms from a recent study:
Protective Glass is Broken The Cause >
Differences in internal and external pressure
>
Large temperature variation
>
Use of alcohol
Hairline Cracks in Prism The Cause >
Mechanical pressure on the outside of the prism
>
General wear-and-tear of the prism
Crystalization on the Prism Tip/Body The Cause >
The prism has been left in the disinfecting solution for too long.
>
The solutions have not been removed correctly
Prism Tip has Broken Off The Cause >
Swabbing with Isopropyl alcohol during the disinfection and/or sterilization process
>
General wear-and-tear of the prism
Poor Disinfection/Sterilization = Damaged Prisms
Damaged or Old Prisms = Potential Risk to Patient or Cross-Infection Prism-Checking_USA_02.13.13.indd 4-6

Replace damaged or old prisms immediately. Always Disinfect and Sterilize your Prisms as Outlined in the Instruction Leaflet. The Goldmann prism instruction leaflet states: “Thorough cleaning under running cold water during 30 to 60 seconds is mandatory before undertaking disinfecting routines”. “Refer to the latest versions of manufacturers instructions for details of the exact concentration, effecting time and application of disinfectant”. “After disinfection the measuring prism must be rinsed thoroughly at least 10 to 60 minutes under running cold drinking water. Dry them with a clean soft oneway tissue and store them in a dry container. Only measuring prisms free of any residue should be used”.
