A message from our President and General Secretary 
Dear Members of ECLSO, dear colleagues, dear friends,

Congratulations and thank you! 

On April 26th and 27th 2024, ECLSO organised an eye and mind catching Congress in Istanbul to celebrate the ECLSO 50th Edition of the Congress. ECLSO welcomed about 200 participants. An international faculty consisting of renowned speakers presented our key topics: contact lenses, ocular surface and myopia. Most striking were the contributions from young ophthalmologists and eye care professionals, who were able to charm the audience into lively discussions.

Congratulations to Dr Penny A. Asbell (USA), who was awarded the Fick-Kalt-Müller Medal and to Professor Chris Hammond, for delivering the Kersley Lecture.

Dr Oguzhan Özçlik, Izmir, Türkiye, received the Best Free Paper Award and Dr Mihaela Petrescu, Nantes, France, was nominated for the Best Poster.

Please note the abstracts of the free papers and posters are freely available HERE.

All this would not have been possible without the generous support of JOHNSON & JOHNSON, ALCON, BAUSCH&LOMB, HOYA, COOPER VISION, DEVA, LCS, PIE INTERNATTONAL MEDICAL and ZEPA KONTAKTLENS, to whom ECLSO extends a hearty thank you.

Any interest in becoming an ECLSO member: please contact your National Representative or become an individual member by sending an e-mail to Ophthalmologists and medical contact lens professionals are sincerely welcome. 


Have a nice summertime!

ECLSO aims to promote continuous education and information of eyecare specialists interested in contact lenses and ocular surface. Our target audiences are therefore ophthalmologists and optometrists with an interest in these topics, including young ophthalmologists and residents in training, as well as allied health care personnel.

Contactology is an integral part of ophthalmological practice. Recent developments in the field of myopia management – a topic all ophthalmologists are confronted with – highlight the fact that medical contact lens approaches are an integral part of ophthalmology.

Not every ophthalmologist has to become a contact lens expert but every colleague must be aware of what is going on in the field.

That is where ECLSO wants to make a difference by organising meetings like the Prague Symposium, the bi-annual Major Conference, and joint meetings with the National Ophthalmological Societies. 

ECLSO sincerely welcomes you to join your National Group or to become an individual ECLSO member. For more information visit the Membership page >>.
