Which is best? iLASIK (Is that InterLase?) Or zLASIK is that what Ziemer Femtosecond Laser is? Whichever one is the best, which machine or it is best? I've heard VISX Star something is great, while there are lawsuits against LADARVision 4000. Lastly, what is a good cornea and pupil size range for LASIK? Any info on pros and cons of: CustomVue LASIK (with Ziemer and VISX Star 4), Pentacam (to map front and back of corneas), WaveScan system. Thank you!!
