Dr Kelvin KL CHONG′s clinical and research interest focus on oculofacial plastic conditions including thyroid eye disease, orbital tumors, trauma, tearing disorders and minimally invasive eyelid, lacrimal and orbital surgeries.

He graduated at the top of his class in the CUHK Faculty of Medicine (MBChB ) program.  He was awarded the Li Po Chun Charitable Trust Fund Overseas Postgraduate Scholarship to the University of California at Los Angeles (UCLA) and LA Biomedical Institute where he returned later for a 2-year surgical and translational research fellowship.  His awards included the City Lion Club Gold Medal, Action for Vision Eye Foundation Young Researcher of the Year, Achievement Awards from American Academy of Ophthalmology (AAO) and Asia Pacific Academy of Ophthalmology (APAO), best surgical video awards in AAO (2012, 2014) and World Ophthalmology Congress (2018).  He has over 40 SCI indexed peer-reviewed articles and 5 book chapters.

Dr Chong currently serves as the Head of the Orbital and Oculoplastic Division at the Department of Ophthalmology and Visual Science (DOVS) and Prince of Wales Hospital (PWH) and the Associate Director of the CUHK Eye Center.

He is the current President of Hong Kong Society of Ophthalmic Plastic and Reconstructive Surgery (HKSOPRS), First Vice-President of the Asia-Pacific Society of Ophthalmic Plastic and Reconstructive Surgery (APSOPRS) and education officer of the International Thyroid Eye Disease Society (ITEDS). He is recently inducted into the American Society of Ophthalmic Plastic & Reconstructive Surgery (ASOPRS).
