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.

Yes that's wright. My capsular bag, as I said, is not intact and even if he had offered me mono vision, I wouldn't have chosen it. But, the problem is Amblyopia and Astigmatism + intact capsular bag.
My friend, you just pointed your finger exactly on what was my main concern. What if my doctor is over conservative and afraid of Syfony because its new? but I've seen posts like this :http://eyedoc2020.blogspot.ca/2014/12/amblyopia-and-intraocular-lens-implant.html
that discouraged me of Symfony. My condition is very complicated. They told me they haven't encountered a patient with my situation. (being Aphakia for 24 yrs after cataract removal)
I have to say one of the docs insisted on contacts but I didn't accept coz for me, it's enough. In addition, glasses are far less harmful than contacts.
The other thing is that I don't have the opportunity to go to Europe especially London to get their opinions. I really can't wait more for the technology to advance more.

First of all don t lose hope or faith poorya0014 having a Crohn diseace taught me that patience and hope are beyond gold..also I believe doctors don t want complaints and they choose the conservative option so as to have success (one doctor of mine told me that if I choose them, it was an institute,I will make friends!!! which was completely irrelevant beacause I asked him if he had operated with the Symfony lenses again!!) ..If I were you I d keep searching for more doctors near my area but if everyone was telling me the same thing I d chose their option..I m near your age and it ***** to not be able to see clear!!!!I drive 8 years and now I dont trust myself to put anyone in the car because I cant see and thats why I decided to do the surgery finally(doctors said to wait as long as possible but its dangerous to wait any longer) ..I m hoping the best for you and a solution to be found as soon as possible!!!
I missed the part about the capsular bag not being intact, I hadn't checked back for earlier posts to see if that had been mentioned. That tends to rule out the Symfony since its a 1 piece lens. They tend to only put 3 piece lenses outside the capsular bag. There are multifocal options available for outside the bag that are just less common.

I had symphony lenses fitted in both eyes On July 15 last year I now have great vision at all distances

I was very concerned   about dislodging my lenses for several months after But the apprehension eventually wares off I took it easy for two months No heavy lifting or sport
Now I'm back to normal without any restrictions and glasses free
Tho I still wake in the morning and reach for my specs
Old habits die hard

thank you for your response Garrry that's very hopeful!!! I am leaning towards Symfony too as I said previously..do you have any issues during night driving??..and after surgery there was a transitional period to get use to the iol or were you able to see "naturally" without any diffuculty or any discomfort??...
I m sorry about all these questions but they 've told me that noone in Greece had those lenses and they made me believe I m taking a huge risk putting those lenses but I don t see it in comparison to a toric monofocal and there isn t any other condition deside astigmatism which will be fixed with the toric version of Symfony!
I have toric Symfony lenses in both eyes and they are useless. I wear glasses all the time. Distance is not too but not clear.  intermediate, which I call TV distance is not clear, and reading is too blurred to read for any length of time.

The last thing I wanna mention is that my problem is rather more mental than physical. If I was your age, that would be different. My father was a driver of any type of vehicle you could imagine for all of his life. He tells me that right now I see more than he does and the reason he drives perfectly is because he is a pro driver and if given the right condition, he even can drive blindfolded. He says the reason of my stress is because I, haven't driven yet, not necessarily due to my vision.
Something I don't understand is that the other 3 docs said that the option of contacts is a very good option for me. I hate contacts. If I am to choose, glasses are better than contacts.
I really wish I could put Symfony, then I'd be probably out of this philosophical to be or not to be dilemma.
So my friend, please tell me everything you think is necessary for me to know so that my judgment be based on reality and truth, rather than propaganda and illusion.
Thank you very much

thank you all for your immediate answers!! the doctor told me I will be fine continuing martial arts even in playing mathces but only after full healing(which didn t tell me how long this will take)..also I ve put a contact lens to stimulate a monovision but it wasn t for me it is causing kind of a headache and dizziness..and yes it seems very akward to have glasses for near but I think it is a habit after a while so I am leaning on the Symfony and if necessary reading glasses(we can t have it all after all) if the Symfony doesn t work for all distances...I was thinking if it s best to leave a 0,5D myopia so to have a middle ground solution and to don t need to wear reading glasses..also I would like to ask how is the night driving did any of you had any problems?? (now with the catarract I only have issues with lights which cause a huge glare due to posterior subcapsular cataract which is in the center of my natural lenses)..also the contrast comparing to natural lens(aka before surgery) how would you describe it??
and also what scares me the most is the accommodating loss of the natural lenses and what would be like to have a any type of iol and that no one can show me how will I be able to see with any kind of iol to choose,now it s a blind choice that I have to take (every cataracts patient to be honest not just me ) that s what troubles me about the whole matter

My friend,
Dr. Stein didn't explain anything to me. He actually saw me for 2 mins. Instead his assistant, Cathy, explained to me what Dr. Stein had suggested. But, on the other hand, wherever I went and to whomever I talked, I was told that Dr. Stein is a pro in his job, so this made me more confident and comfortable, that he is going to do the best possible choice for me. Now, I have to weigh these 2 things to see which one has more benefits for me:
1-I've been living with glasses since 24 yrs ago. The bad: I hate them, I still need to use a magnifier to read, they get dirty and I have to clean them everyday, they limit my visual zone or field. The good: I'm doing OK with them, I've got used to them for 24 yrs! I don't have trouble seeing near (not reading or working with PC.
2-Monofocal IOL set for distance for both eyes. The bad: poor near/intermediate vision, possibility of infection thus evacuating my eyes, needing reading glasses, displacement, I'm not used to it. The good: good far vision, more visual field or zone, not wearing glasses (at least for daily activities), being able to drive, maybe getting better from 20/60 to 20/50 or 20/40.
Am I right? This is a decision for life, man. Cathy said if anything goes wrong, they're not gonna take the lens out and it'll stay there for good. But she insisted that my vision wouldn't become worse than now, if it's not gonna be better and that the probability of destroying the operation with Dr. Stein is low, because he's done 200,000 operations till now.

Man, I like the way you answer. It is clear you've done the research! So, thank you very much for sharing your experiences with us.
But, what you just said, made me more confused. (excuse me for my poor English)
What do you mean by mono vision? My doc, Mr. Stein, said both eyes set for distance with a mono focal IOL. I went to 3 other docs who told me the best option for me is the same thing Dr. Stein recommended. But, now you're saying that: "At your age I would suspect that losing near vision would be   more of a shock..." I'm really afraid my friend. Even right now with glasses, I use a big magnifier to read, but have no trouble seeing people in close. I don't see for example the wrinkles on the face of my dad in for instance 50cm but in 30 or 20cm I see them. So now that you've had both mono focal and multi focal, you're telling me that this would be a concern. don't you?
But, something that all the docs were completely sure of was the fact that Symfony is not good for me. One of their residents, who was a doc, too, told me maybe it's because of the nature of Symfony which finding the right axis is difficult.
You know what, I don't have anything to lose, man. And I am a risk taker; so thinking of my doc's being conservative makes me angry. It makes me rally angry if after the surgery, I find out that I've put all my eggs in one basket that was torn from the beginning and everything is worse that before.

Monovision is setting 1 eye for distance and 1 eye for nearer in. Its commonly done for people who get monofocals to give them better near or intermediate (depending on how far in the near eye is set). Often doctors have people try monovision using contact lenses first (even if they don't usually wear contacts, its just a temporary test). Almost everyone adapts to a small level of monovision (like they'd use with the Symfony) so doctors consider that a safe bet, the issue is to see if someone is comfortable with a large amount if they prefer more near vision.

I'm surprised any doctor these would be talking about having both eyes set for distance with a monofocal, I would suggest trying to find out why they are suggesting that rather than monovision. One thing that crosses my mind is that perhaps you don't have an intact capsular bag to put an IOL like the Symfony into. Most premium IOLs need to go into the capsular bag where the natural lens was removed from. Lenses placed outside the bag are usually monofocals, though I think there are some multifocal options (though fewer than there are for placement inside the bag).

Other than that, if there were an intact capsular bag  there may be some other eye issues that lead them to prefer not to use a multifocal. Since the Symfony is fairly new (especially in Canada where it hasn't been out as long as in Europe) some doctors may be more cautious about it and avoid suggesting it if they wouldn't suggest a multifocal. Other surgeons I've read that have more experience with it seem more willing to implant it even when a multifocal wouldn't be a good idea.

Feedback after 4 months:
My two lens have now settled down.  My Toric right lens still focuses at about 7" to 1 yard, beyond that it gets blurry but my left eye is good at all distances. Unfortunately my brain has not swapped from right eye dominant to left so when driving I am fine until it rains, then I can only only focus on the windscreen.  I have to shut my right eye to regain distance focus.
I trialed a contact lens on my right eye last week. Both my surgeon and the optometrist suggested I would hate it as I would lose reading distance focus, but in a surprise to everyone it was fantastic.  Totally clear vision at all distances, in fact REALLY clear.  So now I am booked in next Monday for Lasic to permanently do what the contact provided. I am super thrilled with my Symfony IOLs.
