Like granite_grrl was saying, there are different procedures and techniques in refractive surgery. In NB, I believe your options are only PRK or Lasik.
For Lasik, they cut a thin flap in the top of your cornea, do the laser, and put the flap back down. With PRK, they scrape the top layer of your cornea off, do the laser, and then put a bandage contact lens on to protect your eyes while your corneas heal. There are different benefits to both types of surgery.
With Lasik, there is very little pain, and much less healing time. But, there can be complications with the flap. Usually if there are going to be any problems with the flap, they happen in the first few days after surgery. But people who are in jobs/sports that put them at high risk of eye injury usually have PRK instead. Also, usually pilots can only have PRK as well, due to the altitude issues.
PRK eliminates the flap, leaving you at a lower risk for complications, but the healing time is much longer. You can expect your vision to fluctuate a bit for the first 1-3 months as your corneas heal. It is a lot more painful as well.
As far as night vision goes, it isn't as big an issue as it used to be, because new laser technology allows surgeons to treat a larger area of the cornea, so you cut down on the difference between pupil size and treater area. EVERYONE after the surgery is going to have trouble seeing at night (glare and haloes) for the first few weeks, as the eyes heal. Usually it clears up, but there will always be a risk that it may be permanent.
If you go in for a consultation at a laser clinic, they can do some measurements and give you an idea of what your risk of night vision trouble would be, and they can recommend the best procedure for your eyes. Where ever you go, make sure you ask lots of questions!!!
