High-end Freeform Adaptation Rate

[McAnerin]

I'm encountering an odd scenario.

My Zeiss and Hoya freeforms are very adaptable with my patients, they generally leave with no problems and I don't see them again other than for adjustments and next years set. For some reason though, my Varilux E and X lenses are having a much lower adaptation rate, even among historical Varilux wearers.

Wheres the big difference between these? Every time I read or test lenses, all the freeform designs seem to blend together, and are nigh-on indistinguishable, other than by the tech buzzwords the reps throw at you.

Anyone know some of the hard truth differences between the different free form designs? (I mean other than Camber vs "x". I have issues with both myopes and hyperopes)

Or maybe I'm just unlucky :)

The only digital Varilux lens that has given me non-adapt problems is the S-design. The X is, in my opinion, the best lens Varilux has ever produced.

I agree with Andrew . I had a real tough time with the S, but I fit a lot of crazy RXs also. The X has been loved by most anyone I've fit for it, save for a few. I dont exclusively fit varilux by any means though, maybe 25-30% of the time.

I'm talking less about my experience with the S (which wasn't great), and more about my patients'. It's the only digital PAL I have a significant amount of non-adapts with).
