neuroadaptation for Vivity vs. Panoptix?
Posted , 8 users are following.
I think i sort of understand why the process of neuroadaptation is needed for a multifocal like Panoptix. (More or less, that the brain has different versions of the image to choose from, because of the rings— and over time, it hopefully learns to choose the clearest one....... maybe?)
My big new question is: Does the same process apply to Vivity? Or does an EDOF lens work differently?
I ask this because I'm having a little trouble adapting to my new Panoptix, and I'm scheduled for a Vivity in the other eye in 4 days, and I'd like to be prepared to know how to interpret my first impressions after the surgery
Also, I’d be so happy to look at articles or videos that explain these things, if you want to point me to any. I love research, and I want to understand all of this as well as so many of you do— but I don’t know where to begin.
Thank you so much!

I have considered both lenses but have not tried either. Right now I have a monofocal for distance in one eye. My expectation would be that the Vivity would be easier to adapt to, and should have fewer side issues like halos and flare at night.
If you have good intermediate and reading vision in your first eye, you may also want to consider a monofocal for distance in the second eye. It has the highest quality vision with the fewest side effects.

Vivity does not require any neuroadaptation

I have nothing to add about Vivity, however, the cataract center where I had my surgery advised me that Panoptix is designed and works best with binocular vision and they would not mix lens types. Panoptix in both or monofocals. They are the top rated center in my area. You might want to look into that.

Really?
So if you had a cataract in your right eye only and implanted the Panoptix and lived with it but did not really like it and then you get a cataract in you left eye, they would only implant another Panoptix.
And if they wont mix and match then how about monovision.
I plan on doing mix and match. In fact I consider the previous IOL I got to be out of date. Am I supposed to put an out of date IOL in my other eye when there are better options.
Maybe they fell the PanOptix and monofocal are too far apart, but in general I disagree with their stance on mixing IOLs.

I've watched enough Ophtalmologist webinars online (with top surgeons from around the world) to say that it all depends on the doctor. Ask a dozen surgeons about their feelings on mix and match and half will say they do it all the time and the other half will say they don't. All we can say is that it's probably fine (otherwise surgeons would not keep doing it) BUT there is little data to back it up. Most clinical trials just test one IOL binocularly. Or might sometimes test a monofocol in one eye + a novel IOL in the other using the monofocal eye as the "control". But you'll be hard pressed to find a trial for every possible combination. That said, again, surgeons can and do go "off label" all the time. But not all surgeons do.

I know the studies show binocular vision is better. But if you are having both eyes done at the same time and doing anything other than a monofocal, I think it is risky as some people do not have great outcomes. I mean if you get a Panoptics IOL and love it then absolutely get another Panoptics IOL in the other eye.
It is when the patient is not happy that I think Mixing for the best overall vision makes sense.
Vision Stereopsis is important and you need to keep that in mind, which is why I warn against too full monovision. As now you are counting on neural adaptation.
But if you had lets say a Symfony in one eye and wanted more close vision. You could do another Symfony undercorrect (monovision) in the other eye or maybe implant a PanOptic. As you say 10 doctors might give you 10 different answers. I think, with no evidence to back it up, there might be an advantage to sticking with same manufacturer, same material, tint and so forth.

not sure if it's correct but they were very adamant about it. They advised panoptix are designed to work in tandem. Something worth exploring if your considering a mix.
I had standard monofocals installed from them, dominant eye distance and intermediate for other

I too am expecting to get Vivity in one eye (next Thursday) and Panoptix in the other (after my first has settled). I am very interested in hearing your resullts.
