For the second year in a row, Dion Paridaens gave a series of lectures at the 2019 ESASO Course on Orbital, Lacrimal & Oculoplastic Surgery Course in Lugano, Switzerland (21–25 January, 2019). ESASO is the European School for Advanced Studies in Ophthalmology.

His three interactive lectures were on the topics of orbital infection, orbital non-infectious inflammation and socket surgery. Furthermore, Prof. Paridaens was an instructor on the dissection course, where he demonstrated an external dacryocystorhinostomy (DCR) procedure, lower lid entropion surgery, upper lid entropion surgery and canthoplasty for lower blepharoplasty to a large group of very motivated young colleagues in the field.
