Dr Kelvin Chong’s clinical and research interest focus in orbital, oculofacial surgery, and related cell biology. He graduated at the top of his class in the Bachelor of Medicine and Surgery (CUHK) program. He was awarded the Li Po Chun Charitable Trust Fund Overseas Postgraduate Scholarship for his observership at the University of California at Los Angeles (UCLA) and LA Biomedical Institute where he returned for a 2-year international surgical (preceptor: Prof. Robert Goldberg) and translational research (Preceptor: Prof. Terry Smith and Dr Raymond Douglas) fellowship. His awards included the City Lion Club Gold Medal, Action for Vision Eye Foundation Young Researcher of the Year, Exemplary Eye Resident Award, Achievement Awards from American Academy of Ophthalmology and Asia Pacific Academy of Ophthalmology. He has published more than 36 SCI indexed peer-reviewed articles and 4 book chapters.

Dr. Chong serves as the Coordinator of the Orbital and Oculoplastic Surgery at the Prince of Wales Hospital and the Associate Director of the CUHK Laser Refractive Surgery Center. He is the vice 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 council member of the International Thyroid Eye Disease Society (ITEDS).
