S12-18 Tonometer Measuring Prism – Safe, Accurate and Environmentally Friendly

19th February 2019

S12-18 Tonometer Measuring Prism, the result of careful consideration and meticulous thinking in supplying an efficient alternative to disposable prisms, providing greater accuracy, safety and an environmentally friendly solution for measuring intraocular pressure (IOP).

Considering the applanation tonometry as a standard practice for measuring IOP, it’s important to keep in mind the environmental damage and cost-effectiveness for the Ophthalmology, Optometry departments and national added costs, when using wasteful disposable prisms. The added annual cost for using disposable prisms is millions more for the NHS in the UK, in addition to tonnes of plastic and paper waste for the environment, compared to non-disposable prisms, research shows. This figure equates to an 853 % annual cost increase for each Ophthalmologist in the UK.

Furthermore, there is a substantially reduced accuracy of disposable prisms and no concrete evidence to support the perceived issue of cross-contamination for non-disposable ones, if adequate sterilisation methods are implemented.

The Takagi S12-18 Prism has been optimised with an integral structure to lower the risk of infection. The structure of the measuring prism comes from being crafted using methacrylic resin to maximise product lifespan. Together with the correct guidelines of disinfection, opting for the non-disposable S12-18 Prism would bring significant financial advantages without compromising patient safety.
