Dr. Chang is considered the most impressive ophthalmolgist I've ever met. He is very thoughtful, careful professional surgeon. After I got his glaucoma surgery on my right eye, vision field was improving. Amazing doctor.

Dr. Chang and his incredible staff are the ultimate in expertise, professionalism, caring, and results. After Dr. Chang's operations on my eyes, I now see better than I have ever in 70 years. Anyone seeking the best in care can do no better than Dr. Chang and Stanford Eye Institute.
