Cataract Surgery - Undilated pupils

    I had Cataract Surgery two days ago. Everything went well and I can see
    very well out of the operated eye.

    One problem I have noted is that the pupil remains extremely closed, and
    I have very little vision in low light. (Is there a better term than

    At a follow up visit to the Doctor, I asked him about it and his comment
    was "they give you some medicine to close the pupil up after surgery; it
    probably hasn't worn off yet".

    OK, it's now 48 hours after surgery and that pupil is still very tiny.
    I will be calling my doctor's office later, but I would like some
    independent advice:

    "How long should I expect this to last? Is this at all a common
    occurrence?" (I haven't seen it described in any of my readings on
    cataract surgery).

    I'm also anxious to determine what my final visual acuity will be, and
    with my pupil acting like a pin-hole, I suspect what I'm seeing now may
    be better than what I'll finally be seeing.

  2. Ask him what that medicine was.
    I'm assuming your other pupil is significantly larger by comparison?
    You might be right on that. I'm hoping your pupil dilator muscle or its
    nerve haven't been damaged, which could cause this. What post-op drops
    are you using?

    OK, I will do that
    I would say it is larger, depending on light conditions. But the
    operation eye remains small, even in dim light (twilight, for example)
    Zymar (antibiotic) four times a day
    Acular LS (anti inflammatory) twice a day)
    Pred Forte (don't remember its purpose) four times a day

  4. Those are good, the pred forte is the main anti-inflammatory one. None
    of these should constrict pupils. Make sure your hands are clean and you
    shake the pred each time you use it, or it won't work well and the
    resulting iris inflammation could cause a constriction. The reason I'm
    mentioning handwashing is once in a while a person will get some other
    chemical or drug on their fingers and into the eye inadvertently...

    After my wife had her cataracts removed she was required to take Cyclogyl
    once a day for a week just to keep the operated-on eye dilated. Supposedly,
    that helped the IOL to settle in. I don't understand why your treatment
    would be so opposite.

    Thanks for the advice on shaking the Pred. I think I've been doing
    that, anyway.

    Spoke with my Doctor Friday night. He is puzzled about the constricted
    pupil, but advises me not to worry (although, I'm not sure what basis he
    has to tell me "not to worry"!) He will try something to dilate the eye
    on my follow up visit next week. I asked him about potential nerve
    damage, and he was quite sure that there wasn't; said that the iris
    would fail wide open, not closed.

    At this point I am functional with the eye the way it is. Long term, I
    would be VERY upset to lose my low-light vision! I have to give careful
    thought before surgery on the other eye, if we don't know what caused
    the constriction in this eye.

    I think I'll do some research on the mechanism of the iris.

    Thanks for much useful information.
