Dr David Chen is an Associate Consultant in the Department of Ophthalmology at National University Hospital (NUH) and Alexandra Hospital. He is currently pursuing sub-specialty training in the field of complex cataract and refractive surgery.

Dr Chen completed his undergraduate medical training at the Yong Loo Lin School of Medicine, National University of Singapore (NUS) in 2015. He was awarded the Dean’s List for his academic performance and invited to the Dean’s Dinner for his leadership qualities. He obtained his Master of Medicine (Ophthalmology) in 2019 and his specialist accreditation in 2021.

During his residency training, Dr Chen served as the Chief Resident from 2019 to 2020, and joined the 7th Singapore Chief Residency Programme. As part of the nation’s response for COVID-19, he was part of the clinician technological team for the Tuas South Community Care Facility from May to July 2020, and was concurrently involved in the manpower allocation planning for the Ophthalmology Department.

Dr Chen’s research interests include ophthalmic imaging, medical technology, and anterior segment surgeries (including cataract and glaucoma surgeries). He has been awarded the Junior Pitch For Fund grant in 2017, the NUH Clinician Scientist Program – Residency (NCSP-R) grant in 2018, National University Health System (NUHS) Innovation Grant in 2019 and NUHS Seed Fund in 2020. He aspires to be a clinician-innovator and is currently completing an Innovation Fellowship with the Singapore Biodesign programme, a competitive national level fellowship to further hone his knowledge in MedTech and healthcare innovation. He hopes to develop portable devices which allow caregivers to perform basic eye examination for patients who are unable to visit the eye clinic, and devise improvements on existing intraocular implants.

Dr Chen also conducts regular clinical teachings for medical students. He is a Clinical Lecturer at NUS Yong Loo Lin School of Medicine and a Clinical Teacher at Lee Kong Chian School of Medicine. He has also been a House Mentor for NUS Yong Loo Lin School of Medicine since 2015, providing guidance to first year medical students and supporting their transition into college.
