You will not know your true vision for 6 months to a year after having surgery.

For me, I was 20/20 after Lasik Surgery. I had a problem with dry eyes after the surgery that took a few years to resolve beleive it or not (they put these plugs in the lower tear ducts).

After that, my vision has been at least 20/15 or better...and that's 5 years post surgery.

I did 6 months of research before doing the surgery. I actually chose the doctor and laser. I found that best results were with the Wavelight Allegretto laser ... the interesting thing was it was not the type that does "custom lasik", but still yielded better results.

Also, I went to TLC laser center and they did about 3-4x more testing than the other 2 doctors I went to.

Go to a surgeon who either uses the Visx or the Wavelight Allegretto ... Make sure they've done tens of thousands of eyes and make sure they are reputable.

You may also want to consider PRK which is where they put the laser on the top of the eye as opposed to cutting a flap ... IT's safer for the integrity of the eye but a longer healing period.
