I just had surgery a few weeks ago and could not be more pleased. I was nearsighted and my correction power for distance was -1.25 (so not a lot), but for work & play contacts and glasses were not cutting it.
My advice is take advantage of free consultations to shop around and get a feel for the people who will be involved in the entire process (nurses, doctors, financing/billing, receptionist, etc.). Also, read up on the different types of procedures, risks/complications, national average costs, reviews, etc. There seems be a lot of bad information on the interwebs, so vet your information carefully. If it is your thing read peer-reviewed literature on the procedures too. Lastly, talk with your eye doctor- they will likely have opinions on certain clinics.
Ultimately, I had a quote for to get LASIK on both eyes for $6,600 at one clinic and $1,400 at another. It was the same procedure with similar equipment. I decided on the less expensive quote and I even felt more comfortable with the staff at that clinic. In summary, just because one is more expensive than the other it does not necessarily mean it is better or you will get better treatment.
