Regarding LASIK surgery, is Custom Wavefront Lasik worth $800 more than Flying Spot Technology? - bausch and lomb spotting scope m49

If someone could provide an informed opinion on the subject I like. My doctor recommended a LASIK or Bausch & Lomb 217z (hover) or Bausch & Lomb Zyoptix (Custom Wavefront). If you are looking for articles on the Internet, all I get are the elements for one or the other, but can not find a comparison. It seems that the more Zypotix is recommended, but it's worth an extra $ 800? Or is the improvement of the wavefront between Flying value custom domain?
