    Hi. I currently wear Sunsoft toric lenses. I have a high degree of
    astigmatism, especially in my right eye, which has a prescription of
    Sph -1.25, Cyl -3.50, and Axis 015. If I want to try another brand of
    contact lenses, do I need to have my eye doctor give me a different
    prescription, or is my current measurement good for all other toric
    lenses as well? Thanks for any info.

    Now I'm confused. I already have a regular pair I'm wearing that the
    doctor gave me. My question is whether I can use this same
    prescription for a different brand?

  3. You can't, because changing the brand WILL change the fit of the lens.
    If you want to try another brand, you have to get trial lenses of that
    brand first, to see how they orient on you eyes. BTW not many
    manufacturers make strong torics like that, so your choice is VERY
    limited, unless you want to seriously undercorrect your astigmatism.

    To be even clearer-- no, you cannot use the same prescription for a
    different brand. A contact lens prescription is brand-specific. The
    identical lens power in a different brand of contacts will not fit the same
    (different plastic, different edge design, etc.). A doctor must try you in
    a trial pair in a brand to make sure it fits first-- if it does then the
    final prescription is given.

    There are several high-astigmatism lens brands that you might try that are
    affordable and of good quality made by CooperVision. I would recommend
    trying Vertex Toric XR, Frequency 55 Toric XR, and/or Preference Toric XR.
    Your eyedoc can arrange trials pairs.

    Fitting high astigmatism toric soft contacts can be difficult. Vision is
    usually not perfect and can fluctuate. Have you tried rigid gas permeable
    contacts (aka hard contacts)?

    Thanks, RM. Your list of specific brands is really helpful. No, I
    haven't tried hard contacts at all, but maybe it's something I should
    think about.

    Thanks for the advice, Mike. Oh, I didn't realize that the trials
    don't cost them anything.

    Oh, one more thing. I assume it's acceptable to go and say something
    like this to my optometrist: "I'm currently wearing this brand of
    contact lenses, but I would like to get Vertex Toric XR instead"? This
    question may sound rather silly, but doctors and the like can be so
    arrogant in general that I was just wondering if it's a reasonable
    request. :)

    how long ago did you get your original prescription for Sunsoft Toric.
    personally, i do have a problem when a patient whom i fit in a brand of
    contact lens and already checked comes back 6 months later and says
    they are having problems with their contact prescription. i wonder why
    they didn't tell me about their problems sooner and why they are coming
    back after so long. some docs I know will charge them a contact lens
    fitting fee if its been a long time since their exam. i am generally a
    softy and i won't charge them again (unless this is a repetitive

    It's been a few months. The reason I want to change isn't that I'm
    having problems, but rather that I want a disposable monthly lens
    instead. He never told me at the time that I could get a monthly toric
    with my high astigmatism--I just found that out from you guys. In
    fact, he made it sound like I could *not* get one.

    Speaking as someone who has fairly high astigmatism (-3.00) - I've
    found that in wanting to wear monthly contacts, I've had to compromise
    on my astigmatism correction. Since the monthly toric lenses with the
    highest powers available here are Bausch and Lomb's SofLens 66 (-2.75),
    Focus Toric (-2.50), and Biomedics Toric (-2.25), and only Biomedics
    Toric fits my eyes, I've had to compromise by wearing a -2.25 toric
    even though I have -3.00 of astig.

    Thanks for the info. What about the Vertex Toric XR? See:

    I'm thinking about these lenses for myself. Frankly, I can live with
    undercorrecting my astigmatism a little. I did that in high school
    when I wasn't even wearing toric at all, even though I had astigmatism.

    Those lenses aren't available where I live, if I'm not wrong, so I
    wouldn't quite know about them (sorry). Well it's best if you check
    with your optometrist before doing anything - I thought the SofLens 66
    would be best for me, but turned out not to be so after the trial
    lenses turned out too flat.

    And errr... I thought I could live with undercorrecting astig (my right
    has has -0.75, and I got a normal lens at first), but ended up getting
    a toric lens for my right eye in the end. I suppose I'm spoiled by the
    fact that my glasses give me insanely good vision, so any difference is
    very noticeable with my contacts. So get trial lenses before you do
    anything? I went through 3 prescriptions for each of my eyes before I
    finally settled on a prescription that I liked. Hope this helps.
