Welcome to Cambodian Ophthalmological Society!

Dear colleagues and friends,

Cambodian Ophthalmological Society (COS) has finally come to its 20th Celebration of the Annual Congress. As a representative of the COS, it is my great honor and privilege to invite you to join this yearly meeting where we basically gather the experts in each of the ophthalmological specialists in entire Cambodia to share and update each other on each individual experience in the ophthalmic field. This meeting is also organized purposely to reunite ophthalmologists and strengthen our relationships.

Established in 2013 under the approval of the Ministry of Health (MoH), our main mission is to keep providing a better quality of eyecare service to all of the patients in Cambodia by advancing the skills of our ophthalmological professionals to the next level. I firmly believe that this annual meeting has played an essential role in making this mission possible. 

As a president, I would like to express my sincere thanks to everyone including stakeholder organizations, and sponsors for their continuous support and contribution to our Cambodian Ophthalmological Society.

Lastly, allow me to express my appreciation to all the organizing committee for making the 20th COS Annual Congress possible. I look forward to seeing you in Phnom Penh, Cambodia.

Warmest regards,

Chukmol Kossama, M.D.

President of COS
