I was introduced to Dr Chang when I experienced an emergency with a sudden retina issue. He rearranged his schedule to perform surgery on me as quickly as possible, including communicating directly with me. He subsequently helped me through other follow up and related issues and I now see better than I have since I was a teenager. Throughout he’s been compassionate and clear in communicating with me about all aspects of my condition and his recommended treatment. His office is also well run and professional and he truly cares about his patients. I would recommend him to anyone and I’m grateful for his help and expertise.

Dr Chang saved my vision with two surgeries. I am forever grateful. I was very anxious and Dr Chang and his staff put me at ease. Everyone was very supportive and professional.

★★★★★ 5.0 John Fabrizio · Dec 2024

I had the good fortune to be referred to Dr. Chang for an urgent eye issue. I was impressed, not only for the care that I received, but in his personable attention and listening skills. He is patient in answering questions and explaining issues, solutions and possible outcomes. The office waiting area is comfortable and well staffed. Very able technicians help with basic testing and examination intake prior to Dr. Chang’s exam. Dr. Chang recently performed successful cataract surgery ( both eyes) for my wife and it was surprisingly easy on her. I can easily recommend Dr. Chang - he is great guy and talented physician!

I had the very good fortune to be referred to Dr. Chang and to have him first do an epiretinal peel at Mass Eye and Ear to improve my scarred macula and then to have lens implants done for both my eyes: a (near-midrange-distance) lens in one eye performed at Mass Eye and Ear, and a (midrange-distance) lens in the eye that had the damaged macula, performed at the surgical unit downstairs from his Waltham office. All surgeries went well, and I love being free of eyeglasses. Dr. Chang is an excellent surgeon, perfectly installing both my lenses. He is thorough and patient, and explains things completely. I appreciate the time he has spent with me explaining the pros and cons of lens choices, and what to expect. He has also performed a YAG on the eye with the macular pucker as well as injected

I cannot recommend Dr. Peter Chang highly enough! He took exceptional care of my mother, performing cataract surgeries on both of her eyes with outstanding results. In addition, he successfully treated her wet AMD with injections, preventing the condition from worsening. Dr. Chang is incredibly knowledgeable, providing top-tier healthcare with compassion and professionalism. What truly sets him apart is how approachable and easy to talk to he is — he takes the time to explain everything clearly, making sure his patients feel comfortable and informed. His fluency in both English and Mandarin is a huge plus, allowing him to connect with a diverse range of patients. Without a doubt, Dr. Chang is one of the best doctors I have ever met.
