Extended Wear Contact Lenses

    I was using Acuvue 2 for about a year, but I grew really excited when
    I heard about Ciba's Night & Day lenses. I just enjoyed having the
    OPTION to sleep in my contacts, if necessary.

    The N&D lenses were never quite as comfortable as my Acuvues...I felt
    that I could see clearer, but I was very aware of my lenses being in.
    Things would also get foggy pretty regularly, and for the first time,
    I needed to carry eye-drops with me everywhere. On top of it all,
    these lenses are not easy to take out or put in. I am unhappy or
    uncomfortable in these lenses about 60% of the time.

    I'll probably go back to Acuvue 2, but I really have gotten hooked on
    the idea of extended wear lenses, especially when I travel or go
    camping.

    It seems like there aren't a plethora of options for extended wear
    lenses. (Patent disputes?) Does anybody know the future of extended
    wear lenses? I've been hoping that J&J might come out with some
    extended wear lenses since I was so happy with Acuvues. Any info,
    suggestions?

    Not so much a need as a desire.

    I wear RGP lenses under Focus Night and Day lenses. Are there plano
    soft lenses out there that are just for daily use? The Focus lenses
    don't last more than a week or two because they're so hard to see. I
    lose them when tring to put them in. Also the lack of color tint
    makes them even more difficult to see. I wear the combination 4-6
    hours per day.

    I don't know, CHip. I'll have to research that one. I'm liking the Acuvue
    Advance at the moment, and it has a blue visi-tint.

    Not sure what you mean by extended. Acuvue 2 can be worn for a week without
    taking them out for a cleaning. They can then be worn for another week
    before disposing them.

    The blue tint makes a huge difference.

    I'm definitely over the whole Night & Day lenses and I'm ready to move
    on. The fact that they're very difficult to take in and out was the
    deal breaker for me.

  7. I guess I've had a different experience with Focus Night & Day. I've
    used various other lenses (Acuvue 1 and 2, Biomedics 55, RGPs), and
    find Focus N&D to be the *easiest* lenses to handle and insert, due to
    their stiffness. I don't find them any more or less difficult to
    remove than other lenses, once you get the technique down. As for the
    handling tint, yes, they are definitely more difficult to see when
    they are sitting in the case in solution, but you get used to it. It
    only takes me one or two tries to get them out of the case just by
    feeling for them.

    Even if these were the most difficult to handle, hardest-to-see lenses
    ever made, I would still use them, because the extremely high oxygen
    permeability far outweighs any handling inconveniences.

    I agree with Lothar in that the Focus N&D seem easier to handle. But, for
    some reason, the Advance are more comfortable for me. I have had cases
    where patients preferred the N&D over the Advance.

    I have horribly dry eyes and having tried both the Advance and the Focus
    N&D I prefer the Focus (taking them out at night). As with most things,
    YMMV. Any news on a Toric N&D?

    Thanks

    Focus N&D has a lower water content than Acuvue Advance, and should
    therefore exhibit less in-eye dehydration than the Advance.

    I don't stay up with Ciba, but one of the doctors in the NG reported that a
    toric version would be out within the near future. I do know that the next
    phase was to roll-out a toric version of N&D.

    Is this right ? I was under the impression that:

    if you wore them continuously for a week you should then dispose of them
    or
    you could wear them for 2 weeks if you took them out each night.

    CHip is doing something called "reverse piggybacking" of a soft lens over
    an RGP. The advantages are twofold. The soft lens surface is less
    hydrophobic than the RGP lens surface. The second benefit is that the soft
    lens effectively hides the edges of the RGP lens, thereby reducing the
    foreign body sensation.

    I haven't. I believe that LarryDoc had posted something recently about the
    status of the patent and when the Purevision would be re-introduced...i.e.
    sometime in 2005. I know that other companies have silicone-hydrogels in
    the pipeline...

    I wear RGP lenses because LASIK caused severe starbursts. Without
    them, I can't drive after dark. But I also can't tolerate the rigid
    lenses more than a couple hours. Two years ago Leukoma suggested
    piggypacking RGPs and Focus Night & Day soft lenses. I found wearing
    the soft lenses under the hard did not work. I then tried putting the
    rigid lenses in first and the Focus soft lenses over the hard. That
    worked better. But the flimsy, clear soft lenses are difficult to
    see. I have an appointment next week to see about Acuvue lenses.

    Pardon my ignorance, but I've seen much talk about toric lenses...what
    are toric lenses?

    My eye doctor and everything I've read says that if you wear Acuvue 2
    continuously for a week, you need to discard of them after a week.

    I can't sleep with Acuvue 2...when I wake up, they're so dry that they
    actually pop out of my eyes.

    And you and your eye doctor are correct and the previous poster is not.

    (USA, FDA) labeling is for one week extended wear and disposal or two
    weeks daily wear and disposal. Simple as that. Cleaning with a rub-on
    cleaner is not recommended and when used daily wear, they must be stored
    in an approved disinfecting solution. Simple as that.

    As always, if they dry out or otherwise uncomfortable or your vision
    changes, you don't wear them in manner you were.

    As you described above one week extended is what the manufacturer recommends
    for both Acuvue and Acuvue 2. I was successfully involved in several
    studies that tested the use of these lenses for 2 weeks. One week, clean, 1
    week and through out. There were no problems noted by the people that I
    talked to on the study and until your postings I believed that 2 weeks use
    was approved. I have been doing it this way for years with Acuvue and
    recently switched to Acuvue 2. In any case, the original message on this
    posting asked a question regarding extended wear. I consider 1 week to be
    extended wear.
