Has anyone had an imbalance ….

Posted , 5 users are following.

Hi there, I had a successful CS on the 31 January on my left eye which was affected by a posterior subcapsular cataract. At the appointment for measurements my surgeon mentioned in passing that due to the difference there would be after, I might want to think about getting my unaffected eye done to balance me up. I am using a contact lense in that eye as before, but feel so off balance and disorientated now, almost like I have a too strong prescription. Has anyone had similar experience ans have gotten a lens exchange simply to even things up? my unaffected eye still has a prescription of -3.25 - is this too great I wonder for me to neurally adapt?

    I only have one eye done and do not have quite that much of a difference between the eyes. I do notice a bit of an issue when I wear my progressive glasses for correction, but do not notice it when I wear a contact in my non operated eye. I would give it some time for you to adapt. If you don't them I guess about the only other option is to get the second eye done too.

      Thank you ! Can I ask, and sorry if this is a silly question, but did your prescription in your non operated eye change after surgery?

      Yes, the non operated eye changed very slightly.

    Hi Andi,

    I had my first eye done set to distance several years ago. It's pretty good from maybe 22 inches out to "infinity". My non-operated eye at the time was still decent enough for near vision but the difference between the eyes was around 2 diopters, as I understand it, which is sort of the limit for mono-vision. It took some getting used to and I don't think I've ever fully been comfortable with it. My non-operated (near-sighted) eye has become progressively worse over time and I need to get a lens implanted. I'm still undecided and not fully informed I think to know what I should shoot for in that eye, but I think maybe -1.25 diopters. I'm still researching this.So in conclusion, you can give yourself a bit of time to see if you adapt, but it sounds to me like you'll want to get your eyes closer in power to each other to achieve a satisfactory result, somewhere less than a 2.0 diopter difference is what I would think. As always, I give the disclaimer....Don't take my advice..get the professional opinion of your surgeon.I wish you the best and let us know how it goes.

    Hi,

    I can't speak specifically to your problem, but I can tell you that when I had my first surgery, I felt so off-balance, almost dizzy. I did need a new lens for my other eye (both of my eyes had cataracts and terrible vision), and once that was done (last week), the off-balance and dizzy sensations have disappeared.

    Not sure this is helpful but I certainly wasn't happy with that sensation.

      Thank you ! Can I ask what your prescription was in second eye prior to surgery?

      All I know is my contact prescription and it varied due to the cataracts. It was between -6.5 to -7.0. Not long before that, I was wearing a -5.50, I believe. And before that, around -7. It kept changing!

      Correction (I can't seem to edit my responses here- sorry): those numbers were for my first eye. My second eye had better vision. My contact for that was -6 at the time of surgery, but it, too, kept changing over the last few years.

    My vision before surgery was around -12 left eye and -8 right eye. My surgeon told me that even though there was nothing wrong with my right eye, I'd need a lens exchange because of the imbalance.

    She was definitely right. I had to wait four weeks between surgeries - I could not get off the couch for the first two, because I would get immediately nauseous. Even with a contact in my right eye, the imbalance was still pretty extreme.

    The sensation of being sick passed after a few weeks, but noticing the imbalance did not. I won't say that I could not have neuro adapted, but I don't think I ever would have been as happy if I hadn't done the implant in the second eye. My brain did not seem to want to fully "fuse" the images into one seamless experience. Could I have lived with it? Probably. Would I ever want to? Nope, it's nice to have them matched.
