"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.

Assessment of Laser Parameters to Improve Lid Tension-A Proof of Concept towards Lasercanthoplasty.

Background: Preliminary clinical work indicates that increasing eyelid tension improves the function of the meibomian glands. The aim of this study was to optimize laser parameters for a minimally invasive laser treatment to increase eyelid tension by coagulation of the lateral tarsal plate and canthus.

Methods: Experiments were performed on a total of 24 porcine lower lids post mortem, with six lids in each group.
