Dr. Samer Hajjo graduated from Aleppo University in 1996, specializing in ophthalmology at Damascus University’s Al-Mouwasat Hospital, completing his specialization with distinction in 2000. Since early in his career, he has focused on strabismus and optics, eventually establishing Syria’s first specialized strabismus clinic in 1999. In 2003, he trained at Necker University Hospital for Children in Paris, obtaining a certified specialization in strabismus and registering two inventions for low-cost manual devices for measuring refractive errors in France. In 2005, Dr. Hajjo founded the Specialized Center for Strabismus and Optics in Damascus, attracting patients from across Syria and neighboring countries. His clinic expanded to three strabismus clinics and an optics clinic, equipped with state-of-the-art technology, and staffed by highly trained ophthalmologists he personally mentored. Dr. Hajjo has performed thousands of successful strabismus surgeries, treated tens of thousands of patients, and holds five international patents in ophthalmology. He has lectured at international conferences, taught optics to postgraduate ophthalmology students at Damascus University, authored Arabic-language books on optics and refractive errors, and taught medical lens material to optics institute students for several years. Additionally, he previously oversaw strabismus clinic operations at Al-Mouwasat University Hospital, served as a board member and secretary of the Syrian Society of Ophthalmologists, and despite his deep ties to Syria, now works in various medical centers in the UAE, Qatar, Oman, and Syria.
