Dr. Robert T Chang is a board-certified, 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, Xen, MP3). His research team harnesses glaucoma insights from big data comprising electronic records, imaging databases, 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, validating predictive analytics, and testing novel portable medical devices for telemedicine. He is formally trained in biodesign (design thinking for medical devices) and process improvement science.
