Doctor knows what he does. He takes his time to explain the procedure. He is very professional.

Dr Chang did my cataract and glaucoma surgery for both eyes. The results are excellent. In both times the surgery went smoothly. He is a great eye surgeon.

I went in to the Stanford Byers Eye Institute to have Dr. Robert T. Chang perform my cataract surgery (that was a big step for me because I'm a Cal Berkeley graduate- LOL). I must add that I previously had a very bad experience with Stanford Emergency-- so I can't say that all Stanford MDs are wonderful-- or even competent. What I can say is that there are not enough stars to give Dr. Chang in this review. He patently answered all of my questions and provided a wonderful experience (I was a little anxious and not the easiest patent). Because of his calm presence, I went into the surgery confident that everything was being well managed by this wonderful doctor, whom I have already recommended to all of my friends.

Dr. Chang is a true doctor, who will move mountains of bureaucracy to make sure his patients, and his patients' family members, get the care needed. I'm updating my review because just today, my family member urgently needed retina care at Stanford and Dr. Chang went and spoke with the best retina specialist at Stanford, requesting that that specialist contact me directly. Dr. Chang single-handedly overcame all the red tape, and the retina specialist contacted our family directly right away. Thank you Dr. Chang! God bless you! Our family is so grateful for you! Dr Chang is a one of a kind doctor. He is not only extremely intelligent and knowledgeable — the top of the field in glaucoma — I was referred to him by another ophthalmologist and actually changed insurance plans so I could see him — but he is also extremely kind, humble and patient. He’ll listen carefully to my concerns, explains thoroughly, and even responds to questions I think of after the appointment that I send him via email. He also is very careful and has scheduled close-together appointments to monitor the condition. My heart feels very much at peace because of his care.

Excellent pat's care and I appreciated

Done cataract surgery by Dr. Chang. Fully satisfied with the process and results.

Dr. Chang was highly recommended by my formal ophthalmologist when she retired. Glad I have him and his entire staff to care for me. He is very knowledgeable, skilled, caring and patient. Had glaucoma/ cataract surgery on both eyes in 2021. Great job! Highly recommend to have Dr. Chang as your ophthalmologist!
