Some clinics claim to do it for half that price, but it seems like they will try to upsell you to a more expensive type of surgery (supposedly more accurate one) after getting you to commit. They even called it "premium lasik".
I could not figure out from any online sources whether there would actually be a difference between the two types of surgery (and if there was, what kind of a doctor would really allow a lesser surgery in such an important situation?), so I decided it was probably just an upselling attempt and decided to go with a clinic that was more straightforward with their pricing and had a less marketing-savvy look to their landing pages.
