The European Association of Eye Hospitals cooperates with many other international associations. Through these contacts hospitals can learn from each other about patient-care, patient-information and efficiency of internal processes.
Since 1993 the EAEH cooperates with the American Association of Eye & Ear Hospitals (AAEEH) in the United States of America. An other relation of the EAEH is the Association of ASEAN Eye Hospitals (AAEH). An agreement of cooperation between the EAEH and the Association of ASEAN Eye Hospitals (AAEH) was signed in August 2006 as part of the 20th Anniversary Celebrations of The Tun Hussein Onn National Eye Hospital in Kuala Lumpur.
The Rotterdam Eye Hospital also cooperates with other eye hospitals who are not a member of AAEEH or AAEH.
