I was at this appointment for over 3 hours. I had a few eye tests, but each test did not take very long. Just quite a bit of waiting.

Dr. Alex Mammen gave me a comprehensive eye exam. After diagnosing that there were three issues affecting my vision, he explained a plan of treatment - three prong approach. He answered all of my questions. He was patient, kind, professional, knowledgeable. He has given me hope that he can improve my vision.
