My girlfriend has been considering having this done also.
It's like any type of risky surgery. If you do your homework and get someone reputable and well known, then you should have good success.
If you go cheap then you run the risk of losing part or all of your vision.
It's not worth the risk to go cheap.
That said, there's always a risk, even with the reputable surgeons, and it's up to you to weigh up those risks with the benefits.
Good luck either way.
Jason.
