my thoughts exactly. and with Symfony in just one eye the natural eye does tone down the Symfony artifacts. these same artifacts are toned down with miotic eyedrops so people with small pupils may not be experiencing this and thus have no need for it. It appears that Symfony / Lara would give a vision of a 40-45 year old (2 feet) while Eyhance would give the vision of a 50-55 year old (3.5 feet).
PEOPLE who experience nighttime issues with EDOF want to seriously consider monofocal. So for us this is a game changer if this gives us something midway between monofocal and edof. At this point spectacle independence is really out of the window for us. So we seek both FOR and AGAINST opinions on a promising new product.
“I don´t think there is any noticeable difference in Symfony and Lara, I really don´t.” - Dr. Romesh Angunawela from Moorsfield UK told me the same thing based on his experience. However, don’t you think JnJ would object to such claims coz this would eat up their european market.
For hitting target I had the eye measured by 5 doctors and opted for ORA intraoperatively. Asked to see the ORA recommendation during the surgery and also made a choice on how much farsighted I wanted to be. Saw the IOL calculations from all 5 doctors myself. I knew I was going with 16.5D or 17D days before the surgery and used Barrett II method recommendations although i had measurements from 5 other methods (holladay, haigis etc.,). So i considered myself sufficiently well versed on hitting target. surgery induced astigmatism of -0.5 is not OK for me and i wear glasses for it. correcting it with glasses or with lasik makes near worse. i was not aware of this before the surgeries.
“If the monofocal gives you usable vision from far distance to 100cm, you will get far distance to 90cm with Eyhanhance on both eyes set for plano, you get a bonus, two eyes normally gives you one more line, that means 20/40 vision at 66cm.” – THIS IS THE challenging part. These distances are different for different people. SO how would you know what an individual is going to end up with?
“20/40 is quite usable, although 20/32 is consideret what we want to feel we have sufficient vision.” AGREED. 20/32 binocular vision with Eyehance at 66cm and I am SOLD on the lens. With Symfony and Eyhance I might be even better.
“Because of the different shapes of the defocus curves of the standart monofocal and the Eyhance, you can create almost any scenario you like to prove a specific point at a specific distance. For a mathematic nerd it is not that hard to calculate and manipulate the numbers, and show the result you would like to show.” – WHAT do you mean? Are you saying they are manipulating numbers?
“If you see the text about the Eyhance, at some point they are mentioning that the Eyhance is making it easier to walk on uneven surface - I think this says a lot, this very far from what we (us premium patiens) demands from our lenses and vision 
” - HA HA..THAT IS indeed drastic. BUT NOONE WITH MONOFOCAL is complaining about walking on uneven surfaces.
I have the symfony in my non-dominant eye so hopefully i could get some better contrast during the day plus not exacerbate the issues at night with a monofocal. Don’t get me wrong, during the day the symfony is hard to beat and I assume two would make daytime even better but make nighttime worse, so I know this is all about deciding which trade-offs you want to live with, at least in theory.
john, i am in the same boat as you albeit with worse night time symptoms due to larger pupil. so i understand where you are trying to get to.
I see what you mean, my hole point is that Eyhance is not that different than standart monofocal, only very little. And some would even not choose the Eyhance I think, because it will have a lower peak.
And yes, it varies from person to, everything does, in theory you need +1,5 to see at 80cm, and +3 to see at 40 cm, but yes, this varies, I only used the mean numbers to put things in perspective.
I know several people with monofocals and monovision, they often target +1.5/+1.75 on the second eye, and this is because of the profile of the monofocal.
The monofocal lens set for far gives you 20/32 at +1, and at this point the second monofocal already have started taking over, giving you advantage of binocular vision in the overlap.
The second monofocal will then peak at +1.5/1.75 and tapers off again giving you 20/32 at approx +2.5 (mean 55cm)
This is mean numbers, that will vary, but it shows that if you have two healthy eyes, you can be covered quite well from far to +2.5 with standart monofocals and monovision, and it will bring you well into midrange with good vision, and maybe even give you a little bit reading vision as well.
Some of my friends have this setup, and it works quite well, one of them never brings glasses with him, he can read as well, monofocals with monovision can work really well if both eyes works fine.
Manipulating numbers - sure they are, most numbers you see are corrected numbers, so everything is right on target, and not the little bit off they always are.
Have you ever been able to get the same gas mileage on your car as the manufacturer states?
If I was payed to make a statistic look a specific way, it is not hard to look at numbers from a group of 100 people, and choose the 25 people that have the right numbers I need for my statistics.
And then choose some distances or diopters where it is especially good for that specific statistic.
These thing are very individual, off course only you know what is best for you.
I have read an article from a surgeon. who also makes lens exchanges, although it was not that often because of side effects.
But when people had severe visual side effects with two multifocals they could not live with, normally he only changed the multifocal in the dominant eye with a monofocal, and then the side effects are gone immediately in almost all cases.
So the dominant eye is also setting the scene when it comes to side effects, I really don´t think you risk a lot with another Symfony, but off course you should go for a monofocal if that is what feels right for you, maybe you would even have the Symfony changed at some point.
Testing have shown, that people in most cases gain 40% extra contrast when both eyes are seeing at the same time, but I guess it depends like everything else.
I already had the YAG done on the symfony eye and unfortunately it made the glare worse–go figure, so i am stuck with that. But what you are saying is interesting and seems to indicate that a monofocal in my dominant eye is the way to go based on that surgeon’s experience. If the dominant eye drives vision quality and my non-dominant eye already has bad rings and glare then it would seem like another symfony would be a bad idea, which is the feedback I received from some doctors. Of course others say they work better together and don’t recommend mixing. I was even thinking that if another symfony made it worse then i could do an exchange to a monofocal but i would rather not have to go through that if possible.
Sorry, I think i keep responding to the wrong person. Just wanted to add to my last comment, if that surgeon swapped out the symfony in the dominant eye for a monofocal and had the symptoms disappear, then i would expect that i wouldn’t have any issues as I still have my natural lens in my dominant eye now and i had problems from day one with the symfony–go figure.
Sorry, I miss-read your earlier post.
Yes, you are absolutely right, if you have the Symfony in your non-dominant eye, it should very much keep the side effects down to a minimum with a monofocal in the dominant eye, this is exactly how the surgeon I mentioned explained it.
Mixing iols have been used for many years, and it works great for many, but you are right that some types of iols do not mix well, but I guess the surgeon should know all about that, there are many designs of monofocals as well.
I am sorry you are stuck with a bad result, I guess that is what we are all affraid of.
And I agree, we don´t want to put in an iol that needs changing…
I agree, that would be logical, maybe you are one of the unlucky few, which doesn´t help you at all.
I hope you it all turns out somehow for you…
That is my concern too John about YAG. I have enjoyed good vision with Symfony snd just noticing LE likely has a bit of PCO or perhaps astigmatism has increased. Need ti gave it checked out but really not wanting a YAG - and won’t as long as vision is good with both eyes open.
I just called the company and the rep had never heard of it. I was asking ‘When will it be available in the US?’ but … if THEY don’t know… who would??
It is now in Europe.
I"m not sure I can follow the descriptions below, but I will try…

funny i emailed them today about availability of synergy in the us and they would offer it without the blue filter.
What’s synergy?

Hi All,
Any real world/patient experience/s with Tecnis Eyehance yet?
My 3rd ophthalmologist ‘Dr Genial’ is recommending OcuLentis Comfort 15 and while I’m not receptive to this option ( two recalls etc) and still ‘focused’ on MMV it would be nice to have another ‘EDOF’ option?
DonD
No personal experience with oculentis but think I read recalls were for serious issues. Opacification of lens itself. If looking for EDOF lens the atLARA and Symfony have much better results.
Hi Sue,
Thanks for that input and have read about lenses you mention but am more interested in the these new ‘EDOF’ options like the Eyehance.
These seem to be more Monofocal but with an add/boost in the intermediate range. Hence seemingly without the potential issues of dysphotopsia?
My 4th ophthalmologist who I just saw and let’s call him ‘Dr Courageous’ himself had two (2) OcuLentis Comfort implanted and is very happy with the outcome although with some minor dysphotopsia. One +15 and one +30 so kinda has a Monovision EDOF solution with a near add from what I understand? 
He also said he did an Eyehance implant the same day for a client but unfortunately too soon to know what the outcome and their experience may be! 
Anyway, if anyone does have any real world knowledge or experience with these new ‘EDOF’ like the Eyehance it will be interesting to hear from them.
Regards,
DonD
