Softlens 66 v.s. Biomedics (Toric) (help)

    I just started wearing contact lenses a few weeks ago, and was given
    Biomedics 55 Toric lenses (for my left eye). It's all nice and good -
    it feels comfortable and I don't even feel it most of the time
    (although it takes me longer to put on this lens than the Biomedics 38
    I was given for my right eye) - if not for the little problem with

    The crux of the problem is that my left eye has astigmatism (cyl?) of
    -3.00, and Biomedics apparently only makes toric lenses up to -2.25.
    (However, apparently Softlens 66 has up to -2.75.)

    The first lens I got gave me such blurred vision that after 5 days of
    wearing it, I couldn't take it any longer and went back to the
    optometrist, who ordered another lens with an increase in the
    compensation for myopia (overcorrection?) to compensate for the
    undercorrection for my astigmatism. This new lens, while much better,
    doesn't give me as acute a vision as I would like. She told me that if
    this lens wouldn't give acute enough vision, the Bausch and Lomb
    Softlens 66 would be another possible lens to try since they
    manufacture lenses that compensate for a higher amount of astigmatism.

    So, after a week or so of wearing the new lens, I went back to the shop
    and was seen by another optometrist, who told me that the Biomedics
    toric was the only toric lens that'd fit my eye (at my first fitting I
    think they actually tried the Softlens 66 but said the Biomedics
    rotated less), and if I wanted any improvement it could only be on the
    right lens (and not the left), unless I went for permanent lenses (an
    idea that I'm not too keen on).

    So what I'm wondering is whether I could actually try the Softlens 66
    even though it supposedly fits less well than the Biomedics Toric, and
    whether it is true that the Softlens 66 wouldn't fit my eye (is it
    because of a difference in base curves?), and also whether the
    difference between -2.25 and -2.75 for astigmatism would be enough to
    justify more rotation in the lens. I'm also not sure if it's possible
    to just go back to the shop and ask if I can just try the Softlens 66
    (even worse because I keep asking for a change in the prescription for
    sharper vision and hence keep getting new trial lenses - I have 2.5
    pairs currently).

    I'm not sure what my prescription is, but this is what's written on the
    blister pack of the last trial lens I got (for my left eye):
    SPH -5.00 CYL -2.25 AX 170 BC 8.70 DIA 14.50

    Also, is it a good fit if later on in the day, the toric lens
    (Biomedics) tends to rotate and stay rotated such that my vision from
    my left eye becomes very unclear and no amount of blinking can make it
    clear again (unless I really really blink a lot)?

    Lastly (slightly unrelated), is there a problem with the fit if, when I
    put the lenses into my eye, I have to move it around a bit and get some
    air trapped under the lens to pop up before the lens will stay in

    Thanks (and sorry for all the questions and the trouble)!

    Thanks. :) I suppose I'll go back and ask if I can just try the
    Softlens 66 toric then, hopefully they'll let me try them. :)

    I'm also wondering if it might be a good idea to get a toric lens for
    my right eye (with -0.75 of astig). Would that be worth the extra
    approximately 26-32 (converted to USD) difference for six lenses (a
    six-month supply)?

    Lastly, are there any problems with overcorrection for myopia to
    compensate for the undercorrection of astig (the current situation for
    my Biomedics lenses)?

    Thanks again. :)

  3. If the refraction shows .75 or 1.00 then yes, if not then no.

    It isa bad idea to overcorrect myopia esp. with contacts, and even worse
    to overcorrect astigmatism.

    Not quite sure about refraction (what does refraction showing .75 or
    1.00 mean actually? I'm not very familiar with these terms as I never
    had to worry about my vision with glasses previously). But went back
    and they're ordering the Soflens 66, with toric lenses for both my
    eyes. Hopefully they'll be better. :) I don't think sunsoft multiples
    are available here actually. They did say that maybe the blur-ness of
    my current Biomedics is partly due to the axis because mine is actually
    somewhere in between 160 and 170, and that if this was the case it
    wouldn't be fixed even with the Soflens 66. Oh well...

    Anyway, I'm just wondering whether lenses can be worn past the
    one-month period if I don't wear them on weekends, and if so, will the
    time I wear them everyday affect this? (I usually wear them for less
    than 12 hours a day) And on a related note, can monthly lenses worn for
    say 10 days, then kept in solution for some time (such as 20 days),
    then worn again for 20 days to make up a month of wearing time? Is it
    also okay to just switch lens care systems, say from AMO's Complete to
    Cibavision's Solo Care Aqua, and is it possible to use Bausch and Lomb
    eyedrops in combination with the Complete or Solo Care Aqua solutions
    (since it's somewhat harder to find eyedrops from either AMO or
    Cibavision than the Renu eyedrops)?

    Lastly, I'm just wondering whether it's safe to nap in the Biomedics
    lenses or the Soflens lenses, for time periods of about 40 minutes (on
    the train, for example, or during lectures :p).

    Thanks again (esp since I've definitely gone off topic). :)

  5. I meant how much astigmatism the eye exam revealed or measured.

    Hmmm I'd assume the refraction is -0.75 (since my current pair of
    glasses has that, and apparently my prescription hasn't changed since I
    got my glasses)

    Anyway, just wanted to say thanks for all the help! :)
