In 2014, he introduced novel endoscopic vitrectomy for retinopathy of prematurity (ROP) to the UK, making GOSH only one of only two centres in the world with expertise in this treatment. With Dr Wong as the Head of ROP Retinal Detachment Surgery, GOSH is now the national surgical centre for the United Kingdom. 

His clinical and research interests include vitreoretinal surgery in adults and children, paediatric retinovascular diseases, genomic medicine and surgical approaches for gene therapy, and vitreoretinal surgical devices development. Dr. Wong is the UK Chief Investigator and Moorfields Eye Hospital Principal Investigator for the RAINBOW trial, an international randomised controlled trial of intravitreal ranibizimab versus standard-of-care retinal laser, as well as being a co-investigator in 3 phase I/II retinal gene therapy trials at Moorfields Eye Hospital. He has over 30 publications, has written numerous book chapters, is the editor of two forthcoming books, has won over 15 prizes over his career and has run over 20 surgical courses as lead or co-instructor both in the UK and internationally.
