Dr Yuen, an ASEAN Scholar and graduate of the National University of Singapore (NUS), is an Assistant Professor in the Department of Ophthalmology at NUS and a Senior Consultant, Ophthalmologist with the Department of Ophthalmology at National University Hospital (NUH). He also serves as the Director of Undergraduate Education for the NUS Department of Ophthalmology.
A femtosecond laser-accredited cataract surgeon, Dr. Yuen has sub-specialty expertise in vitreoretinal surgery, uveitis (ocular Inflammation) and complex cataract surgery. He was awarded the Ministry of Health’s Health Manpower Development Plan (HMDP) award and has been an invited speaker at both local and international conferences, including Euretina and the International Ocular Inflammation Society Congress.
Dr Yuen’s practice focuses on managing complex cataracts, particularly in uveitis patients, as well as the medical and surgical treatment of diabetic eye disease, age-related macular degeneration, and retinal detachments. His expertise includes handling challenging cataract cases, such as:
• Small pupils
• Posterior polar cataracts
• Subluxed/dislocated lenses
• Scleral-fixated lenses
• Implantation of premium intraocular lenses
In retinal surgery, he is proficient in the latest techniques, including 27G small-gauge vitrectomy and scleral buckling, skills he honed during his overseas fellowship with A/Prof Jagjit S Gilhotra, one of the largest users of 27G vitrectomies in Australia. Dr Yuen is also actively involved in advancing medical and surgical retina treatments, ensuring that NUH remains at the forefront of innovation.
In 2025, Dr Yuen became the first surgeon in Singapore and Southeast Asia to perform the first five port delivery platform implant surgeries for age-related macular degeneration. These procedures were conducted at the NUH Department of Ophthalmology, introducing an innovative, long-term, refillable drug delivery system to reduce the burden of frequent anti-VEGF injections.
Additionally, Dr. Yuen was the first in Singapore to gain hands-on experience with intravitreal Vamikibart for uveitic macular edema as part of the SANDCAT trial, contributing to early clinical insights into this emerging treatment.
Passionate about medical education, Dr. Yuen has received the Junior Doctor Teaching Award, Young Teacher Award and the NUHS Teaching Excellence Award for his contributions to training future ophthalmologists. He has also served as an examiner and admissions interviewer for the NUS School of Medicine.
As part of the Core Faculty for the NUHS Ophthalmology Residency Programme, he plays a key role in training the next generation of ophthalmologists. Additionally, he is the designated specialist advisor for the National University Polyclinics (NUPs), where he conducts primary eye care courses for Internal Medicine and Family Medicine physicians.
Dr. Yuen is fluent in English, Mandarin, and Malay.
