Abstract
Background and purposeClimate change is one of the most important threats to human health nowadays. The healthcare industry produces a significant part of greenhouse gases (GHG) emissions. The aim of this study is to assess direct and indirect GHG emissions due to cataract surgery in Spain to identify opportunities for improving. Material and methodsThis observational case series study estimates and analyses the carbon footprint of a single cataract surgery using phacoemulsification in Ávila Hospital. ISO standard 14064 was applied. ResultsThe carbon footprint of a single cataract surgery in Ávila Hospital was 86.62kg CO2eq. Medical and pharmaceutical equipment were responsible for 85% of GHG emissions. ConclusionsCollaboration between pharmaceuticals and ophthalmologists is important to improve the environmental impact of cataract surgery. Future research is needed to introduce changes that do not compromise patient and surgeon safety. Green surgery models could play an encouraging role in the new global health scene.
