I had read that some Monofocals had reported glistening issues. What are the known negative glistening problems that can affect eyesight?

Glistenings are a non issue with Tecnis 1, Eyhance, and Clareon lenses. Older than 2017 productions of the AcrySof lenses has some issues with glistenings. But, even then, it is rare for the glistenings to have any impact on vision.

Some doctors are waiting to see how Clareon plays out re: glistening from what I have read? Interesting that it is before 2017 that the glistening was an issue. I do wonder what exactly are the problems that glistening could cause specially with AMD?

I asked my surgeon about glistenings. Essentially the person having a lens with them can't see them, and they do not impact vision. The surgeon or optometrist can see them with a slit lamp exam. My surgeon said that he has seen glistenings in lenses, but they have never impacted vision in any of his patients.

There are much more important things to worry about than glistenings, and especially with the Clareon lens. Where you set your targets for each eye is going to have the most impact on your vision after surgery. That is what I would worry about in your case. Glistenings are a non issue.

Good info from your Surgeon. I will keep that in mind. I am glad it doesn't impact vision.
No, it is a topic I want to probe and I feel worth my while as well as some of the other issues. I will continue to probe it since I currently have a lot of time until the next surgery.

Keep in mind there is such a thing as analysis paralysis 😉

I know exactly what that is and have dealt with it before. Although I do experience some at varying times, I have it under control because in truth in can be a problem! BUT I always want to know all the facts and am in love with the TRUTH which I pursue on a regular basis. Other times, I shut my brain down and am happy go lucky, cheerful and blissfully dumb!

Glistning is real, but as always, there's some probability involved. It may happen or not. So if it happens, technically you can maitain 20/20 but your quality of vision will be affected. But you wouldn’t notice it because it's a slow process. It's like with poor visual quality - if you don't know how the cristal clear image looks like, you don’t miss it. But I don't think it's gonna be an issue with Clareon. Btw, my surgeon has a case now with massive glistening in Acrysof IQ which requires explanation.

Glistenings WERE an issue of concern back in the early 2000's. The AcrySof material manufacturing process has since been improved starting about 2012 to essentially eliminate the issue. The progress of the improvement is documented in this report.

And also see this letter from Alcon, taken from a presentation by George H.H. Beiko, BM, BCh, FRCSC, about the action they have taken over 10 years ago.

It is important when doing research that one uses the up to date data, and not that from 15 or 20 years ago. I have an AcrySof IQ lens in one eye and a Clareon in another. I was fully aware of this history of glistenings when I chose these lenses, and I have full confidence that they will see me through to the end of my years. The AcrySof IQ lens is 2.5 years old now, and the Clareon one 1 year implanted.

Oh, interesting. Thanks for that valuable information. Hopefully they corrected it with Clareon but may be too early to tell. I will have to look into it further to see how AMD might be affected. I had seen something about it being a problem for glaucoma but haven't researched it yet.

I thought about it very carefully and chose an AcrySof IQ lens and a Clareon lens with full knowledge of the history of glistenings, what causes them, and what has been changed in the manufacturing process to avoid them. My surgeon in addition to doing cataract surgery is a teaching professor at our provincial university. I thoroughly discussed the issue with him before selecting these lenses for my own eyes. I had a choice of the Tecnis 1 and the AcrySof IQ for my first eye done 2.5 years ago now, and I selected the AcrySof IQ lens. We also selected AcrySof IQ Torics for my wife's cataract surgery. When the Clareon lens became available when my second eye was due, I had no hesitation in using it. They are even better. I have absolutely no concern about the quality of my IOLs. I have full confidence in the evolving science of IOL materials. I base my views on facts, not opinions.

If you want to read a credible report on the issue of glistenings, I would suggest this one.

Bottom line is that with today's Alcon lens materials, it is nothing to worry about.

I am glad you keep telling me that as it makes me feel better. Someone else sent me that article which I will read later. Thanks!

Read the report carefully and critically. There is real data in it. Data is truth. Opinions are well, just opinions.
