Silicone Hydrogel lenses won't stay clean

    I had a trial pair of silicone hydrogel lenses from my optometrist.
    The left lens became extremely dirty (areas of fog) after about one
    week. They were removed and soaked every night in a multipurpose

    I went back to the optometrist and he gave me a new pair, along with a
    trial peroxide-based cleaning system. After only a few days the right
    lens has become dirty, especially near the short lines I see on Toric
    lenses, and in the circular area several millimeters from the center of
    the lens. They were cleaned every night, rubbed gently. I even tried
    cleaning them with some old Miraflow cleaner I have around. Nothing
    cleans these areas of whitish stuff off (protein?).

    I've had soft contacts for over 10 years and have never experienced
    anything like this. These contacts become so dirty in such a short
    time, and cleaning solutions won't remove it. The optometrist didn't
    seem to know what was doing this the 1st time I went back.

    Can anyone enlighten me?

    Are you wearing the Purevision toric? You may ask for a trial of the
    Acuvue Advance for Astigmatism. Some silicone-hydrogels depend on a
    surface treatment for wettability. The Advance and Oasys have an
    additive that is present throughout the lens.

    But, yes, I agree with the anonymous poster who said that some
    patients' tear films do not do well with silicone-hydrogel materials.
