Tony,
I believe the one man who had it done just about a year ago did see some improvement. He is in his early 30s and finally decided to do it in hopes that it would improve his quality of life since he has young children.

The other man who is in his late 50s just had his done less than 3 months ago. I do know he had to be hospitalized recently for another crisis.

Both travelled out of state to go to the Mayo Clinic in Minnesota to have their surgery done. They had minimally invasive surgery which goes through the base of the neck.

I stayed at home and had mine done by the cardio-thoracic surgeon who heads up the robotics program at one of our local hospitals. He used the DaVinci robot machine to do the surgery (3 one-inch incisions on the side of my right breast). It's been 11 months since my surgery and I still have some occular symptoms, mainly droopy eyelid and off and on double vision. I only takes Mestinon.
