    During cataract surgery, my mother-in-law's iris was mechanically
    dilated (very painful; insufficient anaesthesia). How usual is it,
    following this procedure, for the iris to be permanently dilated? Is
    this result within the "normal" bounds? Thx. T-L

    Dear Trent,

    This would depend on the drug of choice.

    Atropine (Bella Donna) is the historical drug.

    It is a poision. Most people have no reaction
    as you describe -- but some do. You mother-in-law
    might be that 1 in 1,000 who does.

    Other drugs should be available to counter act
    this effect.

    Her ophthalmologist will know how to do this.

    Great. Otis, don't you feel a little uneasy about giving such medical advice
    especially in a surgicall case such as this?? Or is this now your field of
    expertise?? Don't cha think this is over over your head just a bit??

    To the o.p.- if there was no damage to the iris or sphincter muscle the
    pupil might return to pre-surgery status but there's a likely chance it
    might now be a keyhole or an oval. In any case, I have not heard of
    any medication ( to Otis, atropine DILATES and the pupil is
    already dilated!!) that is utilized if the pupil is permanently altered.

  4. Usually, a large pupil will not affect reading ability after cataract
    surgery. The cataract surgery affects the reading ability, since an implant
    lens has no accommodation for near. This function needs to be replaced by
    proper strength readers or bifocals.
