One thing to consider is what cataract surgeons would choose for themselves, since they moderate links, google this to see the most recent article I'd seen on the topic (the first I recall since the Symfony came out), although its only a few anecdotes rather than a survey/poll:
"What does the sum of all this experience and exposure mean when the time comes for their own cataract surgeries? Here are the informed choices of four leading cataract surgeons."
Where for instance one notes: "Since I enjoyed the monovision so much, I have always maintained that would be my preference. However, after gaining experience with the Symfony IOL, (Abbott) I would probably choose that. My reason is that the Symfony is giving our patients a significantly increased depth of focus. It is also a very forgiving lens with a large sweet spot. I have used it in multiple postrefractive surgery patients, with excellent outcomes.".
Eye surgeons of course are atypical in terms of how cruicial the quality of their vision is and so admittedly many are concerned with the absolute best vision at 1 distance to use when operating with their microscope, which would be a monofocal, rather than what is most convenient. So its actually interesting that many would choose a premium lens. Most people don't have such exacting visual requirements and wouldn't even notice the difference with a multifocal, and the Symfony is even better (I have at least 20/15 vision at distance, they didn't have a line below that to test and that was easy, and that is even without the slight correction which would improve it a bit). I'd seen a presentation video indicating that real world results suggest perhaps to on average expect 20/17 distance with an aspheric monofocal, 20/18 with the Symfony, 20/20 with a spheric monofocal (rarely used) and 20/22 with a multifocal, though I'd seen at least one study where the Symfony had better distance vision than the monofocal control (due to its chromatic aberration correction), while most seem to put them as comparable within the margin of error or a trivial edge for the monofocal.
There are over 20 milion cataract sugeries a year worldwide, and over 480,000 with premium lenses. Most people never come online to research or post unless they have problems (aside from some who of us who researched before surgery and "give back" afterwards trying to kepe things in perspective). Although I don't know the market share of the Symfony, many surgeons seem excited about it so I suspect is growing rapidly. Even a small % of people with problems can lead to a decent number of posts of people with problems. Those who went to the trouble of getting something different are more apt to try to assign blame to the different thing, when the problem may have been one they'd have had with a monofocal (e.g. I see people complaining about what turns out to be the IOL power being off, which would have been even more of a problem with a premium IOL, and almost as high a % get problematic halos even with a monofocal lens, many just don't bother commenting since there isn't much they can do then and they didn't go with anything other than the default treament so they don't comment).
Actually the results are very positive. If you google (they moderate links):
"High rates of spectacle independence, patient satisfaction seen with Symfony IOL"
you'll see a summary of the results of the major studies, indicating:
"In the European studies, subjects were asked if they would recommend the lens to a friend. Nearly all (97.9% in the Europe-1 study and 93.7% in the Europe-2 study) said yes."
That is high compared to results I've seen for other IOLs. It also notes:
"Most subjects who reported symptoms rated them as mild or moderate. In the U.S. study, for example, reports of severe visual symptoms were less than 2.8% for halos, none for glare and less than 1.5% for starbursts.
Historically, we have seen that 3% to 5% of patients implanted with monofocal aspheric lenses report glare and halo, so there is only a small increase in these studies. It is important to note that the use of femtosecond laser, manual limbal relaxing incisions, and LASIK or PRK enhancement were all disallowed during the study, so residual sphere or cylinder error may also have contributed to the incidence of visual symptoms"
Unfortunately its true that a minuscule % of people will have problems that leads them to choose a lens exchange. With anything that isn't 100% guaranteed, *someone* winds up being the statistic (and will likely post about it), so unfortunately no one can guarantee you won't be one of those unhappy patients posting afterwards. So when getting any premium lens you do need to be prepared for that possibility. However it is pretty much guaranteed that you will have a lower range of vision in an eye that gets a monofocal rather than the Symfony. In my case the very high odds of more convenient good vision for what might potentially be another few decades was worth the low risk of needing a lens exchange.

This means that 97.6% of patients get monofocals. Other options seem to be extremely unpopular. Ophthalmologist Uday Devgan quotes a similar, although less extreme number: 85% of his patients get monofocals.

Symfony lens is a good lens, but like many new products, it may have been oversold.
I have a Symfony Toric lens in my right eye for distance and a monofocal lens in my left eye for close-up. With this combination, I have good day vision at all distances beyond 16 inches. However, I wish that my night vision were better, the main issue being the seeing of multiple concentric circles or halos around lights at night time. Many other people seem to have had the same issue. Rather than repeating the details here, I will encourage you to read my post, “Has Any One Else Had This Very Unusual Vision Issue with Symfony Lens?” on this forum. You should be able to find it by clicking on my name and then looking under “Discussion”.

A minor setback, as I love not having to wear glasses any longer. My vision in my right eye is better than 20 20, almost 20 15. My left eye will follow.
When finding a surgeon... having one close to you is important. You may need to make several trips for post opt care, as I have had to do. Well worth it to get a doctor that will keep tweaking your eyes until you get the results you are hoping for. Follow surgeons recommended procedure with eye drops and rest. I am very happy with the care I have been given.

Where did you go for your surgery? How much was the Symfony lens? I live in Michigan and my Dr said $3800 for the lens. I have a standard distance in my left eye. It's just so so but that's because of macular pucker.

Thanks for the quick reply. Ilive closer to Frankenmuth and my surgery will be in Flint. I'm not sure what to do as I had my left eye done 2.5 years ago and they used the lens for seeing distance. My Dr said the cost of the symfony would be 3800 and that's just a bit too much for me. They are talking about doing a lens with intermediate distance for this eye. I have to decide soon as surgery is in a month.

Okay, on reading another message here, Doctor Snyder lets you make payments... each eye is 2800. Your payment would be affordable. Funny, they don't even set a billing date, so far I have sent in a sufficent amount monthly. They do have two types of paying... and they would like it paid within 6 months. There is no pressure whatsoever, and they answer their phone, (no phone tree), Just wonderful people to work with. Do watch the video... it is very interesting.

I would definitely suggest shopping around since prices for surgery seem to vary dramaticall. You might even considering whether to travel to get the lens if the cost difference is worth it.
Unfortunately I don't know what US prices are like. When I got the Symfony in Dec. 2014 it wasn't approved in the US (or even Canada or Mexico) yet so I had to go to Europe to get it. I'd already been planning to travel to get a trifocal if the US didn't approve one, which they still haven't, and then the Symfony came out and I went for that. I wound up getting the Symfony in the Czech Republic in both eyes for less than my high deductible would have been here, including travel. Depending on whether you want laser surgery (I didn't), or need astigmatism correction (I didn't), its perhaps $1200-$2000/eye at various clinics there total for surgery&lens (I got a discount being the first patient to get it there so it was a bit lower).

As I mentioned in another post to you, the test you are doing is actually combining the 2 concerns which I had in one package: the monovision and the double vision due to the different size images due to the different prescriptions for the 2 eyes inglasses. Thus, this is a more difficult combination.for the brain to deal with than what you will have with the monofocal set for reading and the prescription glasses used for distance. Obviously, if this works, that will be great. If it does not and you want to give a more fair test for monovision, you may have to try wearing a soft contact lens of +1.5 in the right eye (unlike glasses, contact lenses don't cause the discrepancy in the image size).

I am not sure what you are trying to tell me. Are you saying my test with the dollar store glasses won't work? I have even thought to try to put on my distance glasses over top of these, but the problem, as I see it, even if I could physically do it, is that the prescription would only be correct for the left eye (the one already operated on) and not necessarily the other eye. So far, about 2 or 3 hours into the test, it seems to be working other than I KNOW I will need distance glasses. I am not sure what you mean by double vision. I am not seeing double, but I suspect that's not exactly what you mean.

If you are doing fine with the modified dollar store reading glasses, that is great! You won't have any problem with the monofocal lens set for near distance in the right eye.
Only if you were not doing fine, I would have said that you should not give up trying a monofocal lens set for near distance in the right eye. Right now, you have a prescription of 1.5D between the left and the right eye, which causes noticable difference in the sizes of images, which the brain receives from the 2 eyes. Some times, the brain can't handle that difference and one may see double vision or just feel that there is something not right with the vision. You won't get a similar change in the the sizes of the images when you get the monofocal lens in the right eye so that it would be a lot easier to deal with. So, if you are doing fine with the modified store glasses, you would be even better with the monofocal lens for reading in the right eye.

You were mentioning a cost of $3800 out of pocket extra for the IOL (since insurance doesn't cover premium IOLs), but there are likely other places that'd do it for much less even in the US. Most places usually price their premium IOLs around the same, but your other post suggested the Crystalens was half that at $1900 (making me wonder if they had a glitch and the Symfony price was for 2 eyes)? which is why I figured that if a local place didn't have a better price, if you couild manage to travel within the US you might find a price that is better even including travel costs. But I know not everyone can swing that, or wish to go through the added stress.
I figured most people wouldn't travel out of the country for surgery but mentioned it for anyone reading the thread who might since you can get it done in the Czech Republic from high quality docs for less than that including travel (though perhaps not if you aren't traveling by yourself, I went by myself).

Good point. I guess I should ask why Symfony is so much higher. Didn't think about that. So far, my experiment with the dollar store glasses is working ok

I will note that if the cataract is noticeably degrading vision then of course it isn't a prefect test. Also the range of vision you have in from there may be different with a monofocal IOL than it is now, depending on how much remaining accommodation you have in that eye. A monofocal IOL may be less than near than you are getting in this test. A test with a contact lens might be a bit closer to what the result would be like than trying it with glasses, but it'd still not be fully accurate due to the cataract and any remaining acommodation.
What the other poster was referring to is the issue that if you have different lens powers in glasses (in this case 0 power in one and +1.5 in the other), that each eye is seeing a difference size image. Glasses change the size of an image, even if most people don't notice it when both powers are the same.How much they change image size depends on the power of the lens. If the image sizes are almost the same, then your brain merges the images and you don't consciously realize there is a difference. If the image size is tooo different then your brain may struggle with it. However now your experiment has a lens power difference of only 1.5 diopters, which is within the range most people adapt to. For those curious to google it, the issue is anisometropia (two different lens powers) leading to aniseikonia (two different image sizes leading to problems merging the images). Except it isn't an issue in your case it sounds like.

I am in route from returning from my second laser treatment on my left eye. I think the extra cost is to cover the surgeon, and other post operative costs that they obsorb as all future tweaks are free from costs... as long as they are part of the Symfony plan. I have just received a laser tweaking so to speak, to remove the astigmatism that was not all removed at the first surgery. This is why I think it's best to have you eyes done as close to home as possible. From February to today... I have had many appointments and my vision continues to get better. I felt it reasonable at 2800.00 per eye that I paid out of pocket for both eyes.

re: "This is why I think it's best to have you eyes done as close to home as possible."
Its possible to have followup visits with a local surgeon even if you travel to get surgery. It partly depends I guess on whether you get a package deal including followups, or if they are done seperately anyway, so that is important to consdier.
In my case I was fortunate enough to not have enough astigmatism preop to worry about so the odds were high I'd only need routine checkups afterwards and not additional treatment . There are higher odds of needing further treatment for those with astigmatism. (e.g. one meta-study suggests those getting a toric IOL have a 29% chance of winding up with > 0.5D residual astigmatism, which most people would want corrected).

I am only a few weeks from the last laser treatment... I hardly notice halos and starbursts now, which really weren't that bad to begin with. Unless I do my macro beading... which is up close about 6 inches away... I have good vision. Before my Tecnis Symfony lens, I had progressive lens that were a pain. They were always sliding down, getting scratched and I needed updated prescriptions every 3 years. So... the Tecnis Symfony Lens are wonderful in my case. Then again, I am not that hard to please.

I wish that my night vision were better, the main issue being the seeing of multiple concentric circles or halos around lights at night time. But a multifocal lens will be the last lens which I would recommend to any one.
My personal experience with the multifocal lenses has really been with the multifocal contact lenses a few years back. I was so unhappy with the vision clarity with those that I switched back to using monovision within a week. Unfortunately, it is not that easy to change the IOLs in the eyes.

Check also with Dr. Barloon in Seattle. Also, my friend hired a private nurse, Nurse Quiana, who drove her to and from the clinic, stayed with her for a couple of days, cooked, cleaned, and even walked her dog while she was recovering. She's a bit pricey but worth every penny. Good luck
