From what I have heard the surgery done in Taiwan is not only more skillful, but also far cheaper. I have spoken with a few people that have had it done here with no problems.
My wife’s ex boyfriend used to live in Taiwan and went back to the states to have his done. A couple of years of dizziness and bad eye sight was what he got for his thousands of U.S. dollars. He eventually came back to Taiwan to have it redone and everything was fine after that.
I can only imagine that because of the larger percentage of people here requiring glasses, that the doctors must get more practice in Taiwan, coupled with the relatively cheaper costs of equipment and setup costs, this seems to make Taiwan number one for surgery and deals on glasses.
