Support teaching, research, and patient care.
Dr. Chang is a fellowship-trained refractive cataract and glaucoma specialist working at Stanford since 2009 and Co-Director of the Stanford Glaucoma Fellowship. He focuses on premium lenses (Panoptix and Vivity) as well as minimally invasive glaucoma surgery (i.e. Hydrus, OMNI, iTrack, ECP, KDB, iStent, Xen, MP3). He has performed thousands of cases and trained many fellows across the country. His funded clinical research and data science team harnesses glaucoma insights from the Stanford Glaucoma Registry of Real World Evidence combining longitudinal electronic records, imaging, and a growing biorepository of aqueous samples. Previously, he helped develop the normative databases for the ubiquitous optical coherence tomography (OCT) and is an expert in testing novel portable medical devices (i.e. virtual reality headsets), enabling home monitoring (Xala Health), and validating algorithms. He is formally trained in biodesign, biopharma, process improvement science, and leadership training.Dr. Chang co-invented the EyeGo Smartphone imaging adapter, which was licensed and commercialized as the Paxos Scope. He previously co-founded a venture-backed seed stage consumer health startup and is a scientific advisor board member to multiple Fortune 500 and small pharmaceutical, med device, and digital health companies. He has served as Vice President of the Asia Pacific Tele Ophthalmology Society and Medical Director of employer based optometry services and regularly speaks on glaucoma and digital technology at conferences around the world. One of his original contributions is the creation of the digital health design sprint, a week-long, fully immersive, project-based learning experience to help doctors, engineers, and business experts be more aware of the challenges in starting a healthcare company.
