Dear colleagues


As President of the Association and on behalf of all ACOS members, I would like to invite you to our 5th annual congress, on December 12 and 13, 2025, in Paris, at the Marriott Rive Gauche Hotel Conference Center.


For 2 years, the round table (WIDES) has established itself with international experts who enlighten the debate and share their experiences. This year, we aim to find a consensus on the diagnostic methods available to us. The International Experts will contribute to the central topics of the corneal epithelium and Meibomian glands. It will be followed by a Gala dinner and a Jazz concert.


Saturday will begin with clinical cases, which provide an opportunity for exchanges between practitioners. This is the DNA of ACOS.

Then, the workshops will take place in 3 sequences and 3 rooms. You can choose between thematic workshops, led by ACOS experts (Contacto, Inflammation, Eyelids, Extreme Surfaces) or sponsored workshops to discover technologies, their uses, and “real life.”

A special feature this year is that we are hosting Veto-Ophthalmologist colleagues from all over the world. They will have a dedicated workshop on Friday afternoon, outside the official program. And then, they will be able to attend the congress with us.

Last thing, the plenary sessions will have a simultaneous translation system into English (on Friday evening and Saturday morning). For the workshops, the size of the rooms allows for multilingual exchanges.

Each year, more and more of you participate, and the subject of dryness and the ocular surface is becoming increasingly fascinating.


The ACOS Meetings are designed to allow medical teams (doctors and assistants) to come together. Take advantage of it.

Finally, the MARRIOTT Hotel has agreed to a special rate for congress participants, accessible from the registration page.

See you soon.
