Dr. Smith has been my eye doctor for years. He always answers my questions, explains things to me. I am well pleased with him as my doctor. My wife has had RK nearly 10 years ago and she says its the best money she has ever spent. Now I understand they do Laser instead of RK and a friend has had that and also is very well pleased. If you want a good eye doctor you can trust to give you advice see Dr. Smith.
