That is VERY difficult to do.
I did great research and found a great surgeon (Mani Menon at Ford Hospital in Detroit).
I was able to get data and interview my top few candidates.
I really had a hard time finding a suitable RO.
I ended up just staying local as the guy seemed very intelligent and personable. But I had some difficulties during SRT and found him to be very defensive, far less than stellar. I really was unable to find a good methodology to seek out a good RO.
One of the problems is it is hard to measure their record of SE. They all say no problems. But the guy I had made it very clear that if problems develop I don't go back to him. I just go see the suitable doctor. Great for the RO. He can claim no problems!
