does it very from state to state or your eyes or the dr?

It varies from doctor to doctor, procedure to procedure as there are several different laser machines and procedures that can be done. It all depends on your own individual eyes. The older lasers (which as far as I know, are still being used) cost less. Something like $900 per eye +/-. The newer procedures can run you something like $1,500 per eye ($3,000 total) or more. Just know that you get what you pay for. Expect to pay a good amount of money for a time tested good doctor. Consider what your eyes are worth to you and pay accordingly.

I had Lasik in 2002 and I paid 2,000 an eye. It's not something I really wanted to look for a bargain on.
