RGP EW fitting - BC vs movement

Discussion in 'Optometry Archives' started by Pipino Il Breve, Sep 4, 2003.

  1. Hi all, sorry for being a nuisance :)

    I have to decide a lens for the right eye between:

    - BC 0.60: the fluorescin says "somewhat too steep" but moves up and
    down correctly

    - BC 0.65: the fluorescin says "ok" but 50% of the times I blink it
    won't come down: it stays stuck up like if it was hanged on the upper
    eyelid. However, if I move the upper eyelid a bit down then up again I'm
    able to make the lens fall. (BTW: Even with Ciba Persecon E the problem
    is the same...)

    The lenses are Menicon-Z-Alpha (dk/t 125) and I plan to use them
    extended wear if possible, in order to avoid coming in contact with
    cleaning solutions as much as possible (allergy). What BC would you

    I'm tempted by the 0.65. I'm thinking that probably the movement
    up-and-down is less important for a hyper-dk lens, is this correct?

    Dear Pipino,

    remember my malediction.

    Some time ago I was saying to you that you will get worse and worse,
    given your HARD stupidity.

    As I foresaw for you, you are worsening even more quickly than it was

    That's your merit: your stupidity is growing, you are an idiot, you
    deserve it!

  3. Dear Rishi!! I missed you SO much

    Yeah I'm having some problems with contact lenses, but even the glasses
    I already have are one hundred times better than your ...cking Bates.

    Pipino, these kind of questions about what to choose have to be cleared by
    the fitter seeing you live.
    He or she has to decide what fits best and this can not be done by internet
    or by yourself.

    Movement in contactlenses is most important to exchange the debris
    underneath the contactlens by changing the tears with the pumpeffect caused
    by this movement also in lenses with a higher dk
