Sustainability in the Operating Room

Surveys of ophthalmologists have demonstrated substantial concern about ophthalmology’s impact on global warming. More than 90% of survey respondents believe that OR waste is excessive.

In this study, the authors evaluated the cataract package variability at 3 different Austrian hospitals. There were 55 different cataract package compositions which differed significantly in size and weight. The smallest package was 57% lighter than the largest package. Drapes, covers, and surgical gowns accounted for the largest portion of weight per package, and the difference in size of the smallest and largest drapes was 71%. This variation is surprising since the technique of cataract surgery is essentially the same throughout Austria. This article highlights the fact that material procurement in cataract packaging is an area where carbon dioxide emissions could be mitigated.

Taboun et al. conducted a literature review on the carbon footprint in cataract surgery. They analyzed six relevant papers in their review and found that the estimated carbon footprint per phacoemulsification procedure ranged from 6 kg CO2 - 181.9 kg CO2. The main factors contributing to the carbon footprint were the procurement of pharmaceuticals, medical equipment and the use of disposable items. The authors also highlighted the sustainable practices of Aravind Eye Centre, which serves as a model for safe and eco-friendly care.
