Biography


Dr. Chang is a fellowship-trained refractive cataract and glaucoma specialist working at Stanford since 2009 and Co-Director of the Stanford Glaucoma Fellowship. He focuses on premium lenses (Panoptix and Vivity) as well as minimally invasive glaucoma surgery (i.e. Hydrus, OMNI, iTrack, ECP, KDB, iStent, Xen, MP3). He has performed thousands of cases and trained many fellows across the country. His funded clinical research and data science team harnesses glaucoma insights from the Stanford Glaucoma Registry of Real World Evidence combining longitudinal electronic records, imaging, and a growing biorepository of aqueous samples. Previously, he helped develop the normative databases for the ubiquitous optical coherence tomography (OCT) and is an expert in testing novel portable medical devices (i.e. virtual reality headsets), enabling home monitoring (Xala Health), and validating algorithms. He is formally trained in biodesign, biopharma, process improvement science, and leadership training.

Dr. Chang co-invented the EyeGo Smartphone imaging adapter, which was licensed and commercialized as the Paxos Scope. He previously co-founded a venture-backed seed stage consumer health startup and is a scientific advisor board member to multiple Fortune 500 and small pharmaceutical, med device, and digital health companies. He has served as Vice President of the Asia Pacific Tele Ophthalmology Society and Medical Director of employer based optometry services and regularly speaks on glaucoma and digital technology at conferences around the world. One of his original contributions is the creation of the digital health design sprint, a week-long, fully immersive, project-based learning experience to help doctors, engineers, and business experts be more aware of the challenges in starting a healthcare company.

I have never been more impressed by a doctor. Dr. Chang has been taking care of my eyes since 2017, when I came to the clinic after botched eye surgery. He is unfailingly professional, kind, and always willing to answer questions. He translates complex medical terminology in a way that is easy to understand. I was very anxious about my cataract surgery, and he took the time to reassure me, and to answer the many questions I posed through email. Every time I go to the clinic, he is mentoring a new Fellow - I always think how lucky they are to be able to work with Dr. Chang. If I had to grade him, I would give him an A+++++++, 5 stars, or the top score on whatever scale I was rating on.

Experience very good.
I was disappointed to learn AFTER the cataract surgery that my reading vision was degraded. This was not explained prior to the surgery, in fact I'm relatively certain I was told that after cataract surgery, it was possible that in addition to improved distance vision, I might experience improvement on reading vision.
Dr. Chang is one of the best doctors.
I have the highest regard for Dr. Robert Chang. I feel very secure in placing myself in his hands.

Good.
Good.
Dr. should explain more about why this kind of things happen . Should explain detail.
Dr. Chang shhowed me a better way of using my eye drops. I have taken Dr. Chang's cards and given them to my local GP.
doctors are so "computerized" these days. entering information in computer during time with patient doesn't seem right (patient can't ask questions as not to disturb doctor), perhaps, this is unavoidable
I thank God for having put me in the care of you all thanks to you all who treat me friendly.
Very satisfied
Dr. Chang has improved a lot in taking time to explain condition and treatments. Very good.
The best.
Dr. Chang is excellent

Very good.
very good
This provider tries his best to get back to me with my questions that I have for him.
Dr. Chang was very thorough explaining to me what has been happening to my eyes, and also clarified my unknown concerns with a plain language. This was my first time having an eye doctor clearly having me understood. I appreciate Dr. Chang's courtesy and language very much.
Very good.
Dr Chang handled everything professionally, kindly, & clearly. I had 100% confidence in his abilities to do the job to the best of his abilities
This was a bad experience. Instead of describing my options to me the doctor told me what option he would provide and I had to ask about other options. Then, he warned that other options cost more money. I believe I should have been presented with all the options and be able to make my own decision, including paying out of pocket for a more expensive option.
Good experience
Dr and staffs were very nice. We were 1 hr late and he was able to take us.
I love my doctor Chang. He is awesome.
These ratings are specifically for Dr. Chang, not anyone else in his practice.
