New RGP lenses - not adapting well

Discussion in 'Optometry Archives' started by Lothar of the Hill People, Sep 24, 2003.

  1. I am a former soft lens wearer who has been trying RGP lenses (Menicon
    Z) for 9 days so far. They were extremely uncomfortable for the first
    few days, but they did begin to feel better, to a point. However,
    even after 9 days, I can feel the lenses every time I blink, and it
    feels like they are rubbing against my eyes or the undersides of my
    eyelids (not sure which). It's a gritty sensation, although I'm sure
    the lenses are clean, and I do not work in a dusty environment. My
    eyes do not look red, even when they are at their most uncomfortable,
    but my vision gets a bit blurry in one eye or the other (usually the
    right) from time to time, usually late in the day.

    At times when my eyes feel particularly irritated or blurred, if I go
    look in a mirror, looking slightly upwards (such that more of the top
    edge of the lens is underneath my upper eyelid when it is fully open),
    I notice that my right lens is sticking a bit underneath my eyelid
    (maybe 1-2 mm off-center), and then slowly re-centers until it sort of
    "snaps" back in position after it clears my eyelid. This re-centering
    probably lasts for a full second with every blink. This does not
    happen with my left eye (that lens re-centers quickly), although my
    left eye feels just as uncomfortable (more so, in fact). If I use
    rewetting drops in my eyes when this happens, the lens re-centers
    somewhat more quickly, but my eyes still feel the same.

    My question is, should my eyes be fully adapted to these lenses yet,
    or is the discomfort that I am feeling still normal at this stage?
    Also, does this sound like a fit problem, a moisture problem, or both?
    I have an appointment with my doctor in 2 days, and I want to have
    some ideas to run by him. The diopter of my lenses is off slightly,
    according to the doctor, so I have to decide if it's worth exchanging
    these lenses for a more accurate power or if I should give up on them.
    If I do order another pair in a more accurate diopter, I wonder if I
    should also try a different base curve or diameter?
