Glaukom: ökologischer Vergleich von Einweg- und Mehrwegmesskörpern für die Applanationstonometrie nach Goldmann

The results show that 44% of the greenhouse gas emissions associated with the measuring bodies can be saved by switching from disposable to reusable measuring bodies. In absolute terms, the greenhouse gas savings amount to 5.6 g CO₂-eq. per IOP measurement. For the University Hospital Erlangen, this already results in savings of 117 kg CO₂-eq. per year and up to 22 t CO₂-eq. for Germany or greenhouse gas emissions equivalent to 212 passenger flights from Berlin to Rome. The analysis also showed that reusable measuring devices lead to additional pollution in some environmental impact categories due to the cleaning effort. In this context the disinfectant bottle and the wipes used for drying the measuring devices are particularly relevant. Overall, switching from disposable measuring devices to reusable measuring devices makes sense from an environmental perspective.
