Dr. Chang is a fellowship-trained refractive cataract and glaucoma specialist working at Stanford since 2009. He focuses on premium lenses (Panoptix and Vivity) as well as minimally invasive glaucoma surgery (i.e. Hydrus, OMNI, ECP, KDB, iStent, Xen, MP3). His funded research team harnesses glaucoma insights from institutional big data comprising electronic records, imaging database, and a growing biorespository. Previously, he helped develop the normative databases for the ubiquitous optical coherence tomography (OCT). Currently he has interest in privacy preserving computational methods, predictive analytics, and testing novel portable medical devices (i.e. virtual reality headsets) and small molecules. He is formally trained in biodesign, biopharma, and process improvement science.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 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. 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.
