Everybody from the moment you walk in is so kind and helpful. I had my right eye done and Dr. Rayburn told me what to expect the next couple of days. The next day I had my left eye done and again, I knew just what to expect. It was quick and painless and so far, so good! My vision keeps getting clearer and clearer as the day goes on.
