my Symfony IOL results after cataract surgery

I'd posted before asking for information about lens options before surgery,  but thought I'd start a new thread now that I've gotten the lens where perhaps others can add their results as well with the Symfony lens. It is a  new type of "extended depth of focus" lens that uses a different design than   multifocal and accommodating lenses.

I had Symfony lenses implanted in both eyes the first week of December.  By 1 week postop my uncorrected vision at distance was between 20/15 and 20/20. At near my vision was already about 20/25 (but fluctuating a bit it had seemed better earlier that day). Given its improvement since then I'd guess its likely 20/20 or so, I can read the small print on my eye drop bottles for instance.  Not everyone achieves this level of near vision with the lens so people shouldn't expect to necessarily get quite as good a result, and should be prepared for the possibility for needing reading glasses at near. I suspect the fact that I'm comparatively young for cataract surgery, 52, might have   something to do with the results.

I had originally only planned on having 1 eye done (since the other was 20/20 correctible still), but when the patch came off the next day I discovered it might be hard to adapt to the difference in vision between the two eyes even with a contact lens in the other eye. I might have quickly adapted if I'd taken the time, but I decided I didn't want to risk it,  so I had the 2nd eye operated on a few hours later.

My intermediate vision hasn't been tested explicitly but I suspect is at least 20/20. That is  based on my subjective sense of it being better than near and because of the design of this lens where visual acuity drops off in a continuous curve from far to near, so intermediate should be around the same as far, definitely better then near. That is one of the differences between this lens and for instance a bifocal IOL where vision may be worse at intermediate than it is at near or far. I spend a large number of hours at a computer and was willing to risk needing reading glasses occasionally for near in order to get better intermediate vision. Most household tasks and social interactions occur at intermediate distance as well.

Unfortunately the lens isn't yet available in the US yet, they are starting a clinical trial here which is randomized with a monofocal lens (there is a 50% chance you would get a monofocal) so I went to Europe for my surgery.  I figured that at my age I hopefully may be using these lenses for a few decades so it was worth a bit of effort to get a better lens. This industry publication suggests it might be  generally available in the US in a couple of years, and that some US surgeons find it interesting:

http://ophthalmologytimes.modernmedicine.com/ophthalmologytimes/news/us-surgeons-anticipate-new-iols?page=0,1
"the Symfony IOL might be available in the US by late 2016 or early 2017...
Of the IOLs discussed at the ESCRS Congress, Dr. Olson and Dr. Packer concurred that the brand new Tecnis Symfony Extended Range of Vision IOL was the most interesting as it represents a new concept for addressing presbyopia that seems to overcome the limitations of multifocal IOLs....

from what I’ve heard so far from respected and trusted surgeons, patients implanted with this IOL are seeing 20/20 at distance and intermediate with very usable, J2 or J3 near vision and are not experiencing any loss of contrast or perceptible problems with glare, halos or other dysphotopsias. So, it looks like they are having their cake and eating it too.”

I had considered the option of getting a trifocal lens which targets far, intermediate, and near (also unfortunately not yet available in the US), or even a bifocal with a small add so its focused more at intermediate than near.  However the studies so far seem to indicate that the Symfony provides better quality intermediate vision. In addition multifocal lenses reduce contrast sensitivity which is useful for night vision, while reports indicate the Symfony is at least as good as a monofocal lens. The other thing the Symfony does is to correct for "chromatic aberration", an issue which is discussed in this industry publication which quotes one prominent surgeon noting:

http://eyeworld.org/supplements/EW-December-supplement-2014.pdf
" Cataract surgery with an IOL with an Abbe number greater than that of the natural lens (47) can improve CA, so that our cataract patients could actually experience better vision quality than they did as young adults. "

Although the Symfony uses a high Abbe material (I'm assuming its the same Tecnis material that article lists as having a 55 Abbe), it also has other features to to correct for CA to improve image quality. It seemed like a good bet the image quality for distance would be comparable, and perhaps even better, than a monofocal lens, or an accommodating lens.

Although some results for the Crystalens look like it will similarly do well for intermediate while providing some chance at decent near vision, some showed a lower chance of good near, e.g. some of the studies listed for the March 2014 update in this government review:

http://www.fda.gov/downloads/AdvisoryCommittees/CommitteesMeetingMaterials/MedicalDevices/MedicalDevicesAdvisoryCommittee/OphthalmicDevicesPanel/UCM346413.pdf

Part of the concern I had with the Crystalens was that in some patients the lens does well, but in some it doesn't accommodate, which leaves it effectively being  a monofocal lens ( but without things like the correction for chromatic abberation). There is also concern I'd read among some  over whether over decades of aging anything would interfere with the physical movement of the lens, something non-accommodating lenses don't require. There is no perfect lens, so its partly a matter of placing a bet on which might work out well, and I figured that it was better to bet on something that didn't require the accommodation to work (in addition to other concerns regarding problems people have with the Crystalens, though those may be fewer in the newest versions). I hadn't searched to find  the study behind the figure in this presentation, but it notes:
http://www.slideshare.net/alanglazier/accommodating-intra-ocular-lenses

that about half of Crystalens patients require reading correction. That may be in part because as it notes: ' "Pushing” does not equal “Sustaining” '. This issue is that someone with their natural lens still who is presbyopic for instance may be able to theoretically read a particular print size without glasses, but that the muscle effort to focus may be a strain to do  for an extended period of time, and the Crystalens at least partly seems to require the same sort of accommodative effort.  (though  there is speculation it may be benefit from some extended depth of focus, which is what the Symfony is designed to use to begin with). I'll continue this in another post in a few minutes.

Re: "...Unfortunately the loss of very near vision will be a new experience for anyone who wasn't yet presbyopic, but its less of a shock than it would be if you went with a monofocal..."
Can you just tell me how this shock is? I remember once one optometrist prescribed me a pair of reading glasses, by which I could not see what was beyond 30 cm . But, I had a very nice reading experience. Do you think my near vision will be like that after mono focal IOL? I mean, for instance, tell me when you look at mirror, what do you see with a monofocal? Is it in a way that you DON'T see anything, see BUT WITH DIFFICULTY or YOU CAN SEE but the image is not clear and you have to get closer or wear your thin pair of glasses?

Since that is a question about a monofocal you might try starting a new page/thread (along with your other monofocal questions) if you want to get comments from people with monofocals (if any are reading the site). I was an presbyopic for a number of years before my cataract so I was used to the idea,  but still didn't like it and fought it off using contacts in monovision and the multifocal contacts.   I was young enough that I hadn't lost all my near vision, and the thought of losing it all with a monofocal (or being forced into monovision with monofocals) was part of why I went for a premium lens. People with presbyopia gradually see their near vision decline over many years so they don't go through the shock of having it suddenly disappear. My near vision with the Symfony is better than it was before the cataract.  How much near vision you get  with a monofocal will vary greatly between people due to variations in their eye's natural depth of focus. A very tiny minority can actually read a bit with a monofocal set for distance, but for most people I'd heard the general expectation was that closer than 6 feet starts to get blurry with a monofocal set for distance, but perhaps others can give a better sense of it.  That is why monovision is useful with monofocals, and   the issue is how much monovision you'd go for, how much nearer one eye would be set than the other.

Well, Cathy, Dr Stein's assistant, told me that his wherever I go, there is only 1 choice of IOL for me based on my eyes specifications and that should be put in posterior chamber. But, just today I noticed something: I think because I have a sever Nystagmus in my left eye (if right is closed I can not concentrate the left to read the Snellen chart and I have to stop my left with 2 fingers from movements to see the chart) and because of this most of the doctors in here, determined my left to be 20/200 but my optometrist, who is a very patient doctor, put time and determined my left to be 20/60!! How is it possible man? I guessed if this is why they think I have Amblyopia (one eye hasn't developed the brain connections correctly like the other eye) and thus Multifocals are not suitable for me, then I have to cancel the whole thing, man. This ain't right. They don't even want to talk to you more than 2 minutes. Man, I know you have got your own troubles but, my English *****! So would you please give me any info about multifocals for my case? for example the name, company brand, or a website I can read more? remember. they said only posterior chamber.

You might want to start a new thread/page asking about multifocals for your case (since people who had your situation aren't likely reading a page about the Symfony, and I think the US doctor here may not always follow threads about the non-US lenses as closely). I don't know of options offhand, I may check at some point, but you could check this site that has a database of lenses:

https://www.mylifestylelens.com/

Or do a search on the net. Lenses meant to go outside the bag are 3 piece lenses, whereas most premium lenses are 1 piece lenses that are meant for placement inside an intact capsular bag. I recall seeing mention in the past of 3 piece multifocals, but I don't know what is currently available.

I hope this isn't off topic but am wondering if anyone knows if and when USA will have symfony available  and why is it not available /approved  now?

They have submitted data to the FDA for approval, but how long it will take isn't predictable, especially since it is a new class of  "extended depth of focus" lens that they had to decide on standards for. I've seen guesses that its likely within a year. It could surprise us and be soon instead.. or take longer. There are trifocals that have been out for a few years longer that aren't approved here, and last I heard they hadn't even tried for approval due to the high cost and long timeline  involved in that process. Unfortunately the FDA is infamous for being slow and conservative about approving new treatments and leaving us a few years behind the rest of the world which often gets to use American technology well before we do. Unfortunately bureaucrats tend to be scolded more if there is ever a problem with something they approve than for being too cautious, so they err on the side of caution. In addition politically they get pressure from those with existing products to be slow to approve competitive products. The Symfony is made by a company that already has lenses on the market in the US so perhaps that leads the company to have more political clout to get it approved. For whatever reason the approval agencies elsewhere in the world aren't quite as bad.

Hi my problem also was astigmatism in both eyes
So poor vision both near and far since I was a child
As I have previously stated I had both eyes fitted with symphony lenses on the same day
The results were instant
The halos and night driving were a big concern prior to my operation
My surgeon was very confident that it would be highly unlikely that I would experience halos
Nine months on I can honestly say that there has been no halos
Night driving is very easy now Though it has taken a while to get used to everything being so much closer
I must confess that I wear lightly tinted sunglasses for driving on bright days
and my eyes are more sensitive to bright sunlight
A very small price to pay

That s why I am going to be operated! I can t drive with sunlight any more it s impossible to see,it s a huge glare and I try with my peripheral vision to see because cataract clouded my central/direct vision)..It s difficult to cross even road in the morning!so besides falls they say its very dangerous for other reasons also!..Garrry thank you so much for your informations! one last question though what would you say was the difference opponent to the natural lens??beyond that you can see clear with the Symfony did you need any adjustment period where there multiple images or by the next day it felt all normal to the brain??(thats what worry me the most if I dont like the sensation)..PS: sorry for all the questions but I ve search this on my one and I am a bit nervous for the outcome because most of the doctors suggest the monofocal option and not for any other issue/condition with my eyes but because everyone or most part of the people(as they told me) in Greece just put monofocal and the doctors dont want complaints which sound ridiculous to me if indeed they have a lot of other options!!!the symfony for example noone told me as an option I told them and they agreed! If I havent told them noone would have told me about them!!!
the sunglasses are the least problem I think and I m very happy for your good outcome!!
Kind regards,
Koncard
At least in the US the average cataract patient is in their mid 70s, so their needs are different than younger patients who will live with the result for decades and are more likely to be more active. They also likely don't want to spend the money for a lens they won't use as long, whereas someone young is making an investment in good vision for a few decades. In my case I figured that even if there were a small risk of a problem that needed  a lens exchange, that it was worth having the bet to have better vision for decades if it worked well  since most people have great results.

In my case for a day or two my near vision went in and out (with distance vision being great from the start), but after that it was fine and I never saw "multiple images" (not something I've seen anyway ever comment on, nor mention in articles).  My near vision did improve a bit, but not much, over time.  
that s what I was thinking and I am searching a better option than monofocal or monovision! the multiple images where an example there could be some other inconvenience the contrast the focus I dont know and because I dont know the feeling/sensation of an enlongated focused lens opponent to natural accommodating lens of the eye..which is causing some worries (or cold feet to proceed to surgery)
There is no different feeling/sensation, you just see everything in focus all at once without thinking about it, just as even eyes that still accommodate with a natural lens do, you just can't see as near as a young person with a natural lens. There is no different sensation to me than wearing regular contacts or glasses provided before, except that my distance vision is shaper than I can remember it ever being and I don't need to wear anything to get that. Unfortunately the loss of very near vision will be a new experience for anyone who wasn't yet presbyopic, but its less of a shock than it would be if you went with a monofocal. A trifocal may give better very near vision so in that sense it may be less of a shock to someone who hasn't had presbyopia, but I think the better intermediate of the Symfony and lower risk of halos make it a better bet still.
as I said I have posterior subcapsular cataract so and now my very near isn t at its best because at the center of my vision its very cloudy so I guess it wont be much of a difference..thank you very much for your immediate answers though!!!In the end I think Symfony is the most risk-free option for me..thank you all very much!
Sorry for my late reply I don't visit the forum very often
Answer to your question was that there was no adjustment period
other than colours being much richer and everything seemed much closer
As I have already stated I had both eyes done on the same day
I expected to be help into my car and then home to bed
I had Perspex covers over each eye but was able to see fine
obviously blurry due  to the the drops and anaesthetic drops
I removed the covers that evening and watched TV  although there was a halo around every light due to the drops I woke up about 430am I removed the covers from my eyes and everything was crystal clear
So sunglasses on and out to the seaside for the day
I was told not to drive till after my two week check-up But in reality I would have been ok to drive after a few days
But waited for my surgeon to tell me that all was well
Good luck with your choices Gary

Thank you man for your hope giving! I'm sorry to hear bout your disease. I completely understand and feel you.
Yes, all 4 doctors I've seen, have told me the best option for me is mono focal set for distance, unfortunately. Though I guess you're wright about doctors being conservative. One of the residents, who also was a doctor himself, told me that her mother had been operated with Symfony and the reason doctors say its not a good option for me is maybe because this type of lens requires risk taking which most of them don't want, as you said, a complaining patient. But, even he emphasized that it would be, at the same time, dangerous, too. Because if it's not gonna be alright, it'll make my vision even worse. But what I thought was that even if this worse case scenario happens, I can extract the lens. However, in my case it'll be very difficult to extract the lens because my capsular impact is not intact.
How old are you? What is your eye numbers? Hopefully in your case it was not a congenital cataract and you're eye is intact. So I'm really happy that you can get Symfony and wish you best luck with that. But, make sure to visit here and say your results.

I m 26 years old and my cataract was caused by 6 years periodic corticosteroid use.That's what all 8 doctors said to me also due to my young age as they claimed!But I ve found a doctor who had experience with Crystalens and Symfony(technis company in general) and it s the same cost to go to London or anywhere abroad(he told me 4500 euros for one eye with six months supervision which covers possible YAG laser as they told me it is going to be necessary while others told me 1900 for the surgery only which is huge difference!!!so beyond healthy risk its a huge cost for my family budget too but its my vision so I hope Symfony will be the best choice and I m not a gambler so I hope I dont regret my choice!!..I m thinking in the next month I m going to do it for my left eye firstly and we ll see after that(hopefully!)
I also have a minor astigmatism thats why I m going for toric version of Symfony
thats my perscription:

If I do it I ll be back with my experience and results!!
Also if I were you I d visit some more doctors,you dont have anything to lose!!!
Only a tiny minority of people need a YAG treatment with modern lenses. I don't know if you meant the 1900 is for surgery with the Symfony, or just with a monofocal.

If  I recall correctly, at least a year or so ago you could   get the Symfony from reputable surgeons elsewhere in western Europe for perhaps 2500-3500 euros, though that only covered the initial postop the day after surgery,  not the 6 month followup that you refer to.. and well under 2000 euros in the Czech Republic (depending on whether you have laser surgery), and somewhere in between in Croatia.
1900 was for a simple monofocal toric lens from 8 doctors I ve search in my country only one who studied in USA(Michigan if I remember correctly) told he can order and operate with the Symfony or the Crystalens..4500 is total cost for one eye and 6 months cover even if I need YAG in this period (he told me its possible because I m young and my eyes generate faster cells thats his explanation,I dont know more)..in that cost 2500 it s the payment of the doctor 1100 its the cost of the lens and the rest its the anaesthesiologist and they use disposable tools as they explain to me for hygiene and to minimize the risk of infection after(also I dont know if everyone uses disposable tools during surgery and he told me to impress me)
I m sorry I didnt explain it better previously
The cost ranges I gave were total costs for preop, surgery, and day 1 postop from prominent surgeons (one of the posters on this site got his in Austria from one of the top surgeons in Europe who had quoted me something in that range), but then you'd add travel expenses and hassle. A quick check shows one site listing 1300 euros and another 1670 euros for a premium lens in the Czech Republic. I had a special introductory  major discount   that others won't get and hadn't checked current pricing. The odds are there won't be much followup in the 6 months postop other than them just looking to see that things are ok, which likely shouldn't cost much, even a YAG most often would happen after that time in the unlikely event you need one.  The risk of PCO may be higher with younger eyes, but as far as I recall most people still don't need a YAG with modern lenses (older lenses led to more people needing them).
oops, I should add that I meant they were total costs *including* the Symfony or other premium lens, per eye.
thanks for the information SoftwareDeveloper..I know its very expensive the exact doctor but he has the best technology equipment and experience in Greece so I think I trust him even the 4500 per eye!
I am going ahead with the Tecnis Symfony lenses and the cost is $3,750 Canadian per eye all inclusive in Toronto Ontario and any adjustments or additional Lasik corrective requirements are included for 3 years thereafter.

You're very lucky my friend. Enjoy your glasses-free life! I wish I were in you. I even don't want 20/20 vision. I just want these glasses to be gone.
