I'm one eye into double cataract surgery, and all I can say is I'm so happy I chose Dr O'Neill to do it. I went from having a -400 prescription and a bad astigmatism to 20/25 vision and virtually no astigmatism in the eye he operated on. I can't wait to have the other eye done. Dr. O'Neill, the nurses, and the office staff have all been great to work with. I've worn Coke-bottle lenses since I was eight years old. These people can perform miracles.
