Dr. Chang is an excellent Ophthalmologist. He fits me in to see him out of his extremely busy schedule & I appreciate that. He did a combined cataract & glaucoma surgery in my left eye on 03/21/22 & it was successful. His assistant surgeon Dr. Peterson is also very kind. My eye pressure was perfect the day after the surgery although my vision was still blurry. But I’m confident that it’ll eventually get so much better. It just takes time to heal. I did not have much pain after surgery. I would like to say that Dr. Chang is a very compassionate; talented; competent; resourceful & hard working Ophthalmologist. I highly recommend Dr. Chang to anyone who needs to see an Ophthalmologist including my family members & friends! Thank you Dr. Chang for your excellent service! This is the reason I came to Byers Eye Institute Stanford. Mabel Lim, M. D.

I have been a patient of Dr. Chang for 6 years. Dr. Chang gives me his best treatment and explains clearly to me every time I see him. He has all my trust due to his profound knowledge in his area and his professionalism.

Dr. Robert Chang provide great vision care for my wife and I over last 12 years. Every visit was professionally exam by the doctors and staff. The phone and email communications are great too. We are so grateful.

highly competent and approachable.

Dr. Chang is considered one of the best ophthalmolgist I've ever met. He is very thoughtful, careful professional surgeon. After I got glaucoma surgery on my right eye from Dr. Chang, the vision field was improving. I almost gave up my right eye vision though he is an amazing doctor. Highly recommend Dr. Chang and Stanford eye institute.

Very professional and intelligent. Easy to talk to. Always willing to answer all your questions. Also has a sense of humor. Would highly recommend him as your Glaucoma doctor.
