Highlighted Patient Testimonials
This past spring, I was unfortunate to have a macular hole in my right eye. This condition required immediate treatment and after seeing two doctors with no solution, I was very lucky to get a referral to see Dr. Chang. He knew what the issue was right away and recommended immediate surgery. Dr. Chang explained everything very thoroughly . Dr. Chang did the surgery and it went well but necessitated cataract surgery a few months later. It has been a long road to this point, but Dr. Chang has been my hero in so many levels. He is extremely talented professionally and listened to all my concerns. Without him, I would be blind by now since I had lost the vision on my left eye to retina detachment many years ago. Thank you Dr. Chang for being so compassionate with your patients. Forever grateful. Ps. My son was so impressed by Dr. Chang that he wants to be an eye doctor when he grows up. He's only 6 yrs old.
Simply put... Dr. Anesi is the reason I can see my beautiful daughter every day. I come from a family with a very complicated genetic autoimmune disease, part of which is uveitis. Dr. Anesi not only fully comprehends the disease but also makes me feel at ease knowing I’m in the best of hands. He’s innovative in his approach to treatments & outstanding when he has performed surgery on my eyes. He is extremely thorough during my exams and always explains his findings in a way I can clearly comprehend and patiently answers all my questions. When I was pregnant he worked with me to develop a contingency plan for treatments should they be needed that would keep my baby & I safe. Boston is known for having some of the best medical care in the world. Dr. Anesi is one of the doctors that makes that statement true.
Dr. Foster first treated me for uveitis over 30 years ago. He has pulled me from the brink of not being able to see so many times I can’t count them. He has always been there for me -always. He is a cornerstone of my medical team and without him, his incredible knowledge and skill, I would be without a lot or most of my vision. He has given me an amazing gift – my sight and I will be forever grateful by the fact that he is my Doctor.
Dr Lou is outstanding and thorough in every way - from the time he spends with you, his caring and compassionate manner and especially his expertise. Can't imagine finding a better Ophthalmologist anywhere.
