    Actually I did not have any experiences on PureVision Toric fitting.
    But I have something to say about AAFA.

    The so-called "Accelerated Stabilization Design" is fine only at axis
    180+/-20 or 90. For oblique axis this lens is as rubbish as Acuvue
    Toric. Rotation of 20 degree or more is almost a must. And the lens is
    often decentre down, thus for high power (>-6.00) Px may complaint
    about "shadows arround things" because of decentred optical zone.
    Soflens 66 Toric is far more superior on these aspects.

    Because in Hong Kong AAFA is the only toric silicone hydrogel lens, I
    want to ask you guys whether PureVision Toric, which is similar in
    design to Soflens 66 Toric, is better than AAFA? And how about O2Optix
    Toric? Is it good?

    Thank You

  2. I just talked to the B&L rep who claims that the PV toric will fit
    almost exactly like the 66 toric. Trials are just now available, so I
    have no experience with the PV toric, but lots with the 66 toric, which
    is my main soft toric lens.
    Thanks for the input on the AV torics. I've not used them much either,
    and will continue to be wary of them.
