iLASIK (IFS 150 Intralase) Vs Z-LASIK (Crystal Plus)?

I have used both systems and have found clinically no difference in my outcomes.  Both of them have similar safety profile.  If you find a surgeon that you are comfortable with, then don't let which is these two laser he uses dissuade you.  You will have the best of technologies in both cases.  Look for a surgeon and a center where you feel comfortable.  Good luck!  You'll be fine.

My experience is almost entirely with the iLASIK.  I have watched cases done with Ziemer and read about it.  The two things that make me prefer the Intralase (iLASIK ) are that there is far more research into the safety of iLASIK, whereas the zLASIK (Ziemer) is much less established technology and the fact that the pattern of laser used by the Ziemer is similar in configuration to older keratome blades. 

I have used both systems and seen no clinical difference. The skill and experience of the surgeon is far more improtant a factor in your outcome than the laser equipment used. Modern laser systems are all extrememly accurate and reliable. I would concentrate on finding a qualified surgeon with whom you feel comfortable.
