Short-term changes to cornea shape/prescription with new contacts?

Discussion in 'Contact Lenses' started by Lothar of the Hill People, Jul 17, 2003.

  1. I am a first-time contact lens wearer who has been wearing Acuvue 2
    and Biomedics 55 lenses (trying to decide which works best for me) for
    7 weeks now. I'm currently using the Biomedics, and the pair that I
    have in my eyes at the moment has been giving me increasingly blurry
    vision for the past week since I opened the package (my last pair of
    the same kind did not do this). I don't *think* it's a moisture
    problem because it's still blurry shortly after I flood my eyes with
    Thera Tears drops. I usually take out and clean my lenses every
    night, although I do sleep in them occasionally (once a week or so).
    It almost feels as if my prescription has changed over the span of
    about a week. My eyes are not generally irritated lately (although
    they were for the first few weeks). My question is this: Is it
    possible for the shape of the cornea to change over this short a
    period of time (or at all) due to contact lens wear, leading to a
    change in prescription? Any other ideas for why this is happening to
    me? Should I try another kind/brand of lens?

    I had a similar problem, but moreso when I took the lenses out. Is your
    vision any different from before you started the lenses after you remove
    them? If so, then your cornea has changed shape. For me, this was temporary,
    but took several days to go back to normal after not wearing the lenses at
    all. What worked for me was switching to gas perm lenses because they had
    better oxygen transfer to the cornea. I cannot wear the soft lenses for this
    distortion reason.
