I didn't get my lasik done here in Chicago, but I would look for someone who uses the laser to cut the flap rather than the blade. That's what I did and I love it! I have large pupils and other surgeons told me that I would have night halos, etc because of having large pupils, but the surgeon with the laser cut said that it gave him more room to work and that I might not have any halos or other negative side effects. I don't have any halos and I see better now at night than I did with contacts. Good luck!!
P.S. Make sure that you get someone who has a two year free adjustment period too - my sister-in-law had to have corrections after her initial surgery and you don't want to be stuck where you can't get that done for free. Also, go for custom lasik - it is very worth it.
