Abstract: Purpose: To estimate the economic and environmental impact of single-use instruments (SUIs) to perform standard cataract surgery in six ophthalmology centers located in Europe and in the United States. Setting: Online survey and interview. Design: Comparative cost analysis based on an online survey with follow-up questionnaire and interview. The carbon footprint calculation was made by ClimatePartner. Methods: Annual costs of reusable instruments (RUIs) were calculated based on data provided by the centers. Annual costs of SUIs were estimated based on the average-selling price of a single-use cataract set of 5 instruments and the reported annual volume of cataract surgery. The calculation carbon footprint of a cataract instrument covered the whole life cycle from production to end-of-life. Results: Annual costs for SUIs were found inferior or similar to the annual costs for RUIs for 4 out of the 6 centers included in this study. The centers where SUIs were demonstrated to be the most cost-effective were also associated with the highest costs of sterilization per instrument. The carbon footprint of 5-years usage of a cataract instrument was found to be 5478.2 kg CO 2 eq for SUIs without recycling, 4639.9 kg CO 2 eq for SUIs with recycling and 20.6 kg CO 2 eq for RUIs. Conclusion: The study demonstrated that SUIs can be an alternative solution to using RUIs in multispecialty hospitals associated with high sterilization costs.
