SCOPUS IDBiography
Dr Choi Kai-yip obtained his BSc and PhD degrees in Optometry from The Hong Kong Polytechnic University in 2014 and 2021, respectively. He has been providing optometric clinical care in the Optometry Clinic since 2014, specialising in Visual Electrophysiology. Dr Choi has actively participated in optometry teaching, mainly in clinical and visual science subjects. He also supervises outbound vision screening service-learning projects tutoring students from optometry and other disciplines, and serving the needy not only in Hong Kong, but also in other places in the world. In addition, Dr Choi actively contributes to optometry development in Hong Kong by serving as a councillor in a professional society and delivering professional development seminars on various occasions.
Dr Choi’s doctoral dissertation was recognised with the 2020/21 Faculty Distinguished Thesis Award of the Faculty of Health and Social Sciences. Publications of his work have also received awards as highly-cited articles in an international journal in both 2017/18 and 2020/21. Combining his research interests with his passion for serving the community, Dr Choi has collaborated with NGO partners and experts from other disciplines to work on improving the well-being of the underprivileged, particularly those suffering from substandard living environments.
Research Overview
Dr Choi’s research interests focus on environmental factors on myopia and the investigation of myopia control interventions using visual electrophysiology. By identifying the visual cues in the environment that aggregate or relieve the impact of myopia, Dr Choi’s research aims to develop novel regimens to mitigate myopia development and progression in children. Moreover, Dr Choi also investigates various eye conditions with visual electrophysiology, aiming to identify biomarkers to facilitate early diagnosis of these diseases.
