Medical Forum / General / Vision / May 2007Cataract 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 "undilated"?) 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.

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? >> 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". > > Ask him what that medicine was.

I would say it is larger, depending on light conditions. But the operation eye remains small, even in dim light (twilight, for example) >> 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 [quoted text clipped - 3 lines] > nerve haven't been damaged, which could cause this.

Zymar (antibiotic) four times a day Acular LS (anti inflammatory) twice a day) Pred Forte (don't remember its purpose) four times a day Rich > Zymar (antibiotic) four times a day > Acular LS (anti inflammatory) twice a day) > Pred Forte (don't remember its purpose) four times a day 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... >> Zymar (antibiotic) four times a day >> Acular LS (anti inflammatory) twice a day) [quoted text clipped - 6 lines] > mentioning handwashing is once in a while a person will get some other > chemical or drug on their fingers and into the eye inadvertently... 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.

Supposedly, that helped the IOL to settle in. I don't understand why your treatment would be so opposite. Patrick |
