Dr Cheong Kai Xiong

Dr Cheong Kai Xiong is an Ophthalmologist at the Cataract and Comprehensive Ophthalmology Department at the Singapore National Eye Centre (SNEC), and a subspecialty fellow in Medical Retina under the Advanced Clinical Specialist Programme. His clinical practice encompasses a broad spectrum of retinal diseases, including age-related macular degeneration, polypoidal choroidal vasculopathy, diabetic retinopathy and macular oedema, and retinal vein occlusion, as well as general ophthalmology and cataract surgery. He has a clinical interest in premium intraocular lenses, specialising in the use of monofocal, toric, extended depth of focus (EDOF), and multifocal lenses.

Dr Cheong graduated from the National University of Singapore (NUS) in 2013 and began postgraduate training in Ophthalmology at SNEC in 2016. He obtained his Master of Medicine in Ophthalmology in 2019, subsequently became a Member of the Royal College of Surgeons of Edinburgh in 2021, and was admitted as a Fellow of the Royal College of Ophthalmologists in 2023. Following his specialist accreditation from the Singapore Medical Council in 2024, he was admitted as a Fellow of the Academy of Medicine, Singapore in 2025.

In addition to clinical practice, Dr Cheong is actively engaged in research, with interests in retinal and choroidal diseases, ocular imaging, and population eye health. He integrates clinical science, epidemiology, and statistical methods in his work. In 2022, he graduated with distinction from the Master of Public Health programme at NUS, specialising in Epidemiology and Quantitative Methods, and was awarded the Lee Hin Peng Medal. He is currently pursuing a Doctor of Philosophy (PhD) at NUS. His research has been published in many leading journals, and he has presented at numerous international and local conferences, received several awards, and serves as a reviewer for multiple journals.

Committed to medical education and community service, Dr Cheong was appointed a SingHealth Associate in Education in 2023 in recognition of his contributions to teaching and training. Fluent in English, Mandarin, and Hokkien, he is dedicated to providing accessible, compassionate, and high-quality eye care to patients from diverse backgrounds.
