Acuvue Advance - flatter base curve needed?

    I went for my annual eye exam and CL fitting this morning. Last
    year I asked about Acuvue Advance, but J&J didn't have the -6.50
    power I needed. I've been using a combination of Acuvue 2 (8.3 BC,
    14.0) along with Ciba Focus N&D (8.4 BC, 13.8). Given that the
    Advance came in the same parameters as the AV2, I was surprised
    that my eye doc recommended the 8.7 BC, 14.0 in the Advance. I
    tried them on and she checked how they did on my eyes. I've got
    a prescription in hand for all three lenses. I'll try the Advance
    for a few days before I decide what to order.

    The Focus N&D were OK depending on conditions. After a while, my
    eyes had a hard time wetting the lenses. I started to notice the
    stiffness of the lenses at the end of the day. I'v never worn my
    lenses overnight, but I've taken quick naps. AV2 was always
    comfortable until they started drying up.

    I trust my eye doc, but my question is more out of curiosity. Is
    there typically a move to the flatter base curve with Acuvue
    Advance?

    It's good that you trust your eye doctor, as his/her judgement should
    be preferred to someone who hasn't yet examined you.

    However, my Acuvue Advance fitting distribution is about 80% 8.3 and
    20% 8.7. This seems to be in agreement with just about everybody I
    speak with, including some of their consultants.

    Well - after about 4 days on the 8.7 Acuvue Advance, I'm finding that
    the right lens occasionally feels loose. The left feels fine. It
    felt like the time I had the wrong trial lens with the N&D. It just
    started floating around a little bit before settling down for long
    stretches.

    Then I was going to try it again on Wed, and I thought I saw some
    debris on the right lens. It was two little tears. I saved them,
    and maybe my eye doc will want to see them. This morning I tried my
    second trial pair. The right was intact. The left seemed a little
    malformed at the edge, but I (stupidly) put it in anyways. I just
    called up the doctor's office, and I'll be picking up a pair in the
    steeper base curve.

    I like the Acuvue Advance although I am having some initial fitting
    problems. The "malformed" lens isn't giving me any problems,
    although I'm just going to throw it away. It came in different
    packaging - a rather large blister pack, and only said "Galyfilcon A
    smaller Acuvue retail blister pack.

  4. That's the original packaging of the trials when the lens was
    introduced. Should be the same as one with identical parameters of the
    smaller (newer) packaging, emphasis on "should".

    My O.D. said it was otherwise identical. I've seen all sorts of
    repackaging of contact lenses. I once had a single Biomedics 38 lens
    to replace a torn "generic" equivalent (Proflex 38). Then I found out
    all the "house brands" that Ocular Sciences produces, including
    Proflex, Ultraflex, Optimedics, Mediflex, Polysoft, Aqualens,
    Flextique, Sofmed, Versaflex, Target (for sale at Target stores), etc.
    At a new eye doc, I got "Ultraflex 38", but she said I could have a
    Biomedics 38 prescription if I wanted to shop elsewhere.

    Oh - the new steeper base curve lens seems to be stable on the eye.
    It might take a bit more adjustment time though. What was really
    strange was that the 8.7 only felt loose periodically. It was fine
    while sitting in the examination chair.
