"Dirty Dry Eye"- A waste volume analysis from topical therapy in keratoconjunctivitis sicca.

Purpose: The healthcare system is responsible for around 5% of CO emissions globally and in Germany. So far, there are no data on the amount of waste from dry eye disease (DED) therapy in ophthalmology. The aim of this project was to evaluate the amount and type of waste from single- and multi-dose units (SDU/MDU) generated by eyedrops used to treat DED in Germany.
