I had my last Rx prescribed w the iProfiler. I got a pair of Zeiss Drivesafe and I was completely underwhelmed . I then had my lab make a Camber Steady, IOT Alpha 45, FEA Constitution and Seiko GX3, last 2 being cheapo lenses and all of them were as comfortable as the Zeiss. I entered all of the Rxs as prescribed down to 0.01D and all were further compensated to wrap tilt and VD.
Money carefully refunded
I'm a little worried now as if I do repeat iprofiler measurements, the cyl axis and amount might vary by 5 degrees or 0.25, especially on lower cyls. When you then let the software calculate the iscription, you can get quite different results. I've now changed the settings on the iprofiler just today so it now does 10 instead of 3 wavefront readings per eye. It only takes 30 seconds more in total or there abouts. This seems to give more repeatable results. But anyway like I said, a work in progress for now.
Interesting. Thanks for the info. Please, keep us updated. Wow, 5 degrees. That's huge. If I take my difficult patient from the last thread with 4.75 DC, that would be a massive shift. It would basically ruin the Rx. (Plus he's a picky $&#%!. I swear he can tell if something if off by 0.12 D)

I believe the larger axis differences only occur on low cyl powers.
Depends on topography of cornea, profile of lens and pupil size
