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.
