Course Designed by Robert Chang, MD


Dr. Robert Chang, an alum of the Biodesign Faculty Fellow Program runs a busy glaucoma and cataract surgical practice with special expertise in minimally invasive glaucoma surgery and complex cataract removal. He is an expert on optical coherence tomography (OCT) having helped the development of Zeiss Cirrus. He emphasizes precision medicine using OCT and visual fields.


Besides state of the art clinical care, cutting edge research, and world class education (> 100 lectures including international teaching and volunteer work), he is involved in the development of novel mobile health devices and digital health startups as well as scientific advisor to multiple pharmaceutical and medical device companies. Current research interests include: differentiating high myopia from glaucoma, improving glaucoma medication compliance, eye care screening with mobile devices, computer vision machine learning, and validating and commercializing new medical devices and digital health.

Dr. Chang co-invented the EyeGo Smartphone imaging adapter, which was licensed to Digisight Technologies (now called the PAXOS scope He brings translational medtech to the market to improve patient care. He is also the co-creator of an immersive, cross-cultural Stanford-China entrepreneurship graduate seminar ( and leads several hybrid biodesign hackathon seminars including Hong Kong (, Brazil (, Beijing, and Stanford.


He is a Fellow of the Stanford Center of Innovation for Global Health, a Biodesign Faculty Fellow, and Lean Launchpad educator. He also won first place in the 2015 Philips Healthsuite Hackathon and the 2016 Robert Howard Design Award to improve his team's latest consumer medtech wearable for air pollution.
