2 contact lens questions

Discussion in 'Contact Lenses' started by GuyPaul Thibault, Jun 13, 2005.

  1. 1- Do both lenses have to be the same type? My wife has a toic lens to
    correct asigmatism in one eye, but why does she have a toric lens for the
    other eye? Are we getting screwed?

    2- With soft disposible lenses is there really any risk to different BCs
    other than fit? My Dr is thinking of switching me from a 8.7 to a 8.2, and
    maybe to a different brand with a 8.4. It seems pretty hap-hazerd.

  2. Are there risks with being fitted too loose or i sthat just a comfort thing?

    There is perhaps the risk of developing giant papillary conjunctivitis
    from the constant rubbing of the edge of the contact lens against the
    superior palpebral conjunctiva....

    ....which ultimately happens with GPC. The lens adheres to and moves up
    with the lid. I don't know about your experience, but in the presence
    of GPC, I always go steeper. Actually, I go in the direction of less
    edge-lift, which does not necessarily mean steeper.
