Robert T Chang MD is rated 5 out of 5.0 based on 50 ratings.

Dr. Chang is very intense about achieving great outcomes, which is exactly what I want from a medical professional. Up-to-date techniques and equipment. Supported by excellent technicians and colleagues. Not chatty, so come prepared with your questions and concerns; they will be addressed succinctly but with genuine kindness.

Dr. Chang’s work is masterful, but more than that he is truly compassionate. I truly appreciate how he helped give me my vision back.

Dr. Robert Chang is an excellent ophthalmologist at Byers Eyes clinic at Stanford in Palo Alto California. He is excellent at his craft, amicable and reassuring. He took time to see me during an emergency, explained my particular eyes issue and the treatment required to treat it. I highly recommend him.
Antonietta Bonfiglio Vetere
Dr. Robert Chang is an outstanding ophthalmologist and researcher at Stanford. Several years ago he diagnosed my eye disease and detected unusual characteristics that other physicians might have either missed or dismissed. He also performed successful, innovative surgery on me this past year. He is thoughtful and attentive. I understand from his colleagues that he undertakes important and creative research as well, benefiting a wide range of patients. In sum, I can’t recommend Dr Chang highly enough.
Karen Recht
Dr. Chang is really thoughtful, caring, and always has an eye toward what the latest innovations and developments are in his field. I'd highly recommend him for anyone with eye care needs, particularly glaucoma.
Ravi Pamnani
Dr. Chang is one of the top glaucoma specialists in the US. He cares deeply about his patients, he’s very tuned into the latest research, and he confident but not pushy — he’ll bring in other opinions and works well together with other doctors.

I have seen a number of Opthalmologists in my search for Glaucoma care & cataract surgery & none can compare with the care I’ve received from Dr. Robert Chang and the staff at Byers Eye Institute. I recently underwent surgery for cataract removal with lens implant & Hydrus stent implant. The surgery went exactly as described & the results were quite successful, as I had hoped. Dr. Chang is caring & compassionate. He explains things quite well & answers all questions. Everyone in the surgery center made me quite comfortable & at ease. I will not hesitate to have my second eye done & am in the process of scheduling it now. I hope my review will help anyone who is contemplating seeing Dr. Chang & can wholeheartedly highly recommend he & his staff. You’ll be in good hands.
