Has Any One Else Noticed this Unusual Vision Issue with Symfony Lens

They can't get any specific personal information from cookies unless you provide them with it directly by filling out forms on this website with your name, address, etc. (and there are no forms on here like that as far as I know), unless law enforcement requests that information from them and they then get it through your internet service provider (and you would have to do something really compelling to have law enforcement request your information). They just have generic information according to what you do on the site and no other info about you other than that.

If driving at night is important to you, then considering your personaI  experience with the halos, starbursts etc with the Symfony lens in the left eye, I will strongly suggest going for a monofocal lens (set for distance) in the right eye.

Essentially, if done correctly, your vision with the Symfony lens in the left eye combined with the monofocal lens in the right eye will be about what you have right now. It looks like that at least, you can live with that. If you are lucky, your night vision with the left eye better may get slightly better, but don't ignore the night vision issues. In spite of the surgeons telling the patients that the halos or the multiple circles around lights will go away with time, as you have read in posts by many people in this forum, those often stay unchanged with time.

There is hardly any downside to getting a monofocal lens in the right eye. Your day time vision at the intermediate and the near distances will be about the same as right now (although yes, it won't probably won't get any better as it may slightly with the Symfony lens in the right eye).

Why pay extra money to get a Symfony lens in the right eye just to get potentially small gain in your day time vision at the potential risk of getting much worse night vision than you have right now!

 

hi m22031 , do you Have Symfony Multifocal or Symfony Extended focus ( ZXT /ZXR) ?

it is a bit too late. I did the same mistake .did both eyes a week apart with out enough research or proper doctor consultation and choice of lenses some places you can have a trial external lens . If you want you can delay , but once you change the non-dominant the halos will become a bit more obvious the size stays the same , they say that can be less bordering after 6 Months

The Monofocal . is an option for the Dominant eye in your case left eye . As the driving and far distance is dominant eye responsible

Please check my posts for my issues , i Made that mistake i did both eyes one week apart just around 2 months ago

The star Burst will become really , bad in my case with no good distance or intermediate vision . But that is correctable

In saying that if you use Symphony  EOF , that is the best results over all ZXT or ZXR models on the market and hope that you get the best result . BUT GLARES , halos ARE PRESENT AND ONLY SOME people get used to it . Most doctors or researchers do not say it like that

There was one person in this forum who said that he hardly notice it , and that coul dbe the case after 6 Months

Check if you are using Symphony Multyfocal or Symphony Extended focus !!! Extended focus gives better results in halos and glares 

I still prefer to try  Crystal Lenses AO adaptive but no one is doing it in New Zealand .  I would happy extract my Symphony at least in the dominant eye and replace it .

i Have given 7 Months for adaptation and check that some of the other side effects do not kick in .Just finished LASIK correction yesterday in the dominant eye . After that if still not good  will replace my dominant eye with monofocal if i can not find clinic with adaptive lens

 

I could not agree more , but one correction you do monofocal with distance in the dominant eye in his case that his left eye

Sue is very good in this forum and if he can comment would be great

mm2301's left eye is already done. Thus, there is no more any choice for the left eye.

The only choice at this time is about what to do about the right eye. And in my opinion, the best choice at this time is a monofocal lens set for distance for that eye.

P. S.  It does not matter, but by the way, I think that I was probably the first one on this post and on this forum ( about a year back) who suggested getting a monofocal in the dominant eye for distance (combined with a Symfony for the interrmediate distance) to get the benefits of Symfony while minimizing the night vision issues.

Agree but swapping the dominion eye could be a struggle by it self so better consult with your doctor this option

And mm2301 you should know how you use your eyes more

Distance or near. For me distance is better I am ok wearing glasses for near or intermediate . Probably if I knew after the first for what I know now would go with mono for the nondominant if I had option. But is very personal . Peronally now I will try with the two symphony to achieve best result and then if something will fix the dominant eye. But hey extra risk and very personal feeling .

Hi at201, is your right eye implanted with Symfony Toric lens, your non-dominant eye? Your Tecnis Symfony Toric lens (Model: ZXR00) would be the state-of-the-art lens and pricier than the Tecnis Toric IOL (Model: ZCT), isn't it? The reason I am asking is, my husband's vision seem to be improving even after nearly 2 years of implantation with Symfony EDOF lenses.

heard of that one before, achieving best result pairing eyes with same lenses. Spasibo.  haha you're quite a linguist by leaps and bounds.

Sorry at201, please ignore my question above. I just read your reply to coppp that your right eye is the dominant eye. But I would be interested to know if you continue to see improvement in your Symfony eye. Thank you.

I did have a Lasik enhancement free of charge about 5 weeks after the cataract surgery to correct the astigmatism caused by the rotation of the Symfony toric lens from the installed position.

While that improved my day vision, it did not make any difference in the night vision effect of seeing the concentric circles or halos around lights at night. There has been no change in my seeing the concentric circles or halos around lights at night over the last 20 months, since I noticed them soon after the cataract surgery and getting the Symfony lens on December 1, 2016.

I would blame it on the new lenses if I could

Thank you jan for the comment that helps.

By the way only second day after lasik on the dominant eye and I can see a lot better and the halo is not so bad still there but can drive. And distance vision restored to almost 80% from the original with glasses. Near better

May be just we need to relax and the doctors need to prepare us for the long and painful jurney in advance not a day or two .

Thank you (and everyone else) for the responses.  This is an incredibly helpful and supportive community, and I am so grateful.   People who haven't experienced these issues can't really understand.  

As long as I am able to manage with the contact lens in the right eye, I am going to delay doing anything with the right eye.  I had to stop using contacts over a year ago due to ongoing irritation and GPC (tried different brands, using drops, nothing helped, but it seems better now, perhaps due to treatment of dry eye with Xiidra).  I  thought I would be able to wear my progressive eyeglasses with the left lens removed, but that didn't work at all.     I am interested to hear what my surgeon's response will be.  He is associated with one of the best eye hospitals on the East Coast, but I think his patient interaction skills are lacking; I don't feel that he listens well to my concerns and seems to be in a hurry to get on to the next patient. 

I also think it is possible they didn't properly identify my dominant eye, but I hope I am mistaken.  This is based on the homegrown test of making a circle with both hands, looking at an object in the distance, and then closing one eye at a time to see which eye is looking at it.  When I do this, it's my right eye looking at the object, not the left, which the doctor says is my dominant eye.

I will update the forum after I see the doctor Friday (8/3).

Hello, I am relatively certain that I have the Symfony EOF but I will confirm.   I know that it is supposed to have the lowest incidence of night vision issues, but that is not the case for me. 

In general I adapt easily; I had no problems at all going to multifocal contact lens and then progressive eyeglasses, so I don't think I am overly sensitive. 

It's a bit difficult to describe what I'm seeing at night, but I'll try.  With an overhead streetlight, the light itself is blurry, there's a small halo, and then there are starbursts all around.   The starbursts glare and halo as well.   The diameter of the starburst is as wide as a standard traffic lane.    It's the same with car headlights; the diameter of the starbursts covers the lane the car is in as well as at least half of the traffic lanes on each side.  As the lights get closer, sometimes the starbursts fade enough that I can see the concentric circles others describe.    

That describes my experience exactly, although I get the concentric circles always. I am now investigating surgeons in Southern California who are experts at explantation; hopefully I can find someone and start again with monofocals. I know that it is risky, but I can't imagine another 25 or 30 years with these night driving problems. It has also affected my ability to enjoy live theater (halos around the performers depending on the stage lighting), television (halos around light objects against a dark background), and even the night sky. I do not expect anything to change as it has now been 12 months that I had the second eye done.

Where are you in East Coast?  I am on East Coast too - in Canada.  Can relate to surgeons busy - our Medicare system is great in that the surgery is covered no matter your lens selection but they do not have time for lengthy consults.

Also the tests one can do at home to determine dominant eye - although helpful can be misleading.  In my case when I did those tests I thought I was left eye dominant but the cataract in my right eye was worse than left eye so my left eye became the dominant eye.  Now that Ian almost a year out from surgeries doing those same at home tests - it is my right eye that is dominant.   When I asked my surgeon about that before surgeries he didn’t put much stock into dominant vs non dominant eye - but that could be because I wanted plano to be the target for both eyes so it wouldn’t matter which eye he operated on first etc.

Wishing you the best.

How long has it been since your surgery?   I have 2 Symfony EDOF lenses (regular not toric).  In the first 5 or 6 weeks I had strong glare starburst etc.  So strong didn’t even see the concentric circles.  But as time has passed that glare and starbursts has diminished a lot.  Now I basically see the concentric circles and although large - don’t affect my driving at night as much as the glare and starbursts did. also as I drive closer to light source like red traffic light at a particular distance they disappear altogether.  Those haven’t diminished with time but I guess I get used to them when driving and they aren’t a constant distraction.  But I haven’t avoided being out at night walking or driving so they may be part of the process of adapting (at least for myself).

Sorry Jerome that must be difficult.  Although I see concentric circles around certain lights like red traffic lights or cars when they brake I haven’t had that issue for inside (TV movies or live theatre).  That must be annoying for you.   I wonder if there is another cause for that other than the lenses?  Hoping you find a solution.

Hi Sue.An, I'm across the border in the Philadelphia, Pennsylvania area.  It's only been about 10 days since the surgery on my first eye.  I am scheduled to get the Symfony in my right eye on August 6, however I am very hesitant to do so given the night issues and less than optimal distance vision from the first Symfony.  I don't have any medical reason to do this immediately and I think I can manage with a contact lens in my right eye for a while.  I will discuss options and get recommendations from my surgeon at my follow up on August 3.    If he still thinks Symfony is the best option for me, I am going to wait and see if the night vision improves.  As someone else pointed out, there's no reason to risk permanent deficiency of night vision to gain a small  improvement in near vision.

I'm happy to hear that night vision does improve for some.  If I only had the circles, with minimal glare and starburst, I think I could manage.    Only time will tell!

Hi Jerome, I am so sorry to hear of your experience.   I hope that you are able to find a solution.   I have only the one Symfony currently, and I do find that night vision is much better when I use both eyes (one with a contact lens).   Perhaps replacing just one of the Symfony lenses would be helpful.  I think the doctor's offices should provide patients with photos and/or videos illustrating the possible night vision issues.   The likelihood may be low, but that doesn't matter if you're the one it happens to. 

If there is no need for cataract surgery on your right eye I would encourage you not to proceed for reasons you state.  Nothin good is as good as your natural lens.  My cataracts were such there wasn’t an option to wait.  In time perhaps there will be a better lens.  

Hello all, an update after consulting with my surgeon on 8/3.   I have Symfony Extended Focus, which is supposed to have minimal risk of halo / glare.   Distance in my left eye is not optimal, and he also said I have mild astigmatism.   We are going to try eyeglasses with a  -.25 Sph / -.75 Cyl to see if they help with general blurriness and the night vision.   Right eye surgery is postponed.  My doctor said the period between having the first / second eye done is the most difficult to adjust to.   If the glasses don't help and I decide the Symfony is not for me, he suggested a monofocal in the right eye.   He also said the vision in the left eye can be improved with a PRK procedure if needed, but that wouldn't be done for several months.   He mentioned that removal of the lens is a last resort option but thinks it is unlikely it will be necessary.

I feel much better after this visit and I retract my earlier statement about my doctor's patient interaction skills.  He listened to all of my concerns, walked me through my options, and was in complete agreement that we should not proceed with the right eye at this time. 

I will let the forum know how the glasses work out.

Thanks again to all for your support.

Hi i tried glasses after the both eyes operations and helped a lot for the blurriness on a  distance above 1m

R: sph 0 , cyl - 0.75, axis 45 , L: sph:0.25 , cyl -1.00 axis 0.75 . I think the CY:L and axis is the main problem

But did very small difference on the halo and glare , but getting used to that and reduced effect overtime

After Laser correction on the dominant RIGHT eye i do not ware the glasses any more for distance 

Still halo is there , glare is not very strong . If i put the glasses on the left is still better

The Halo starting to become less bordering , still all the time there but kinda reduced in comparison the rest of the objects . I think since the blurriness was reduced now the brain starts to adjust and adapts to that . And some angles of vision the halo almost disappear

 

This one confusing site to use. I noted technis revised it online app. It shows assorted results of the lens they make. Multi focal have greatest halos at night symfony fewer or less pronounced and monofocal even less. However the range of clear vision is so great in symfony and multi so it is a trade off. I see many opthal now explain strengths and weaknesses of various lenses..     and and stress certain personalities should not get any but monofocals

Seems wrong people are on list as satisfied do not post. The app is in the App Store and worth looking at

I had some dry eye after surgery and dr has me using warm packs each am. Seems corneas do affect vision more than I knew 

Interesting can you post a link to that app

Also something interesting to read

https://advancedvisionsurgery.com/blog/1562017dont-believe-the-hype-symfony-lens-has-the-same-rates-of-haloes-and-glare-as-other-multifocal-lenses

I went on the simulator and although glare is about what I see at night there is no simulation of the concentric circles and no mention of them.  I agree some doctors are more careful in patient selection as not everyone will want to accept the trade-offs (and some no matter what personality type they are - due to their work and hobbies should consider anything but a monofocal lens). 

Still don’t think Tecnis site does enough to show a potential candidate the actual night vision view of this with Symfony lenses.  One has to wonder why they don’t as by now there is no doubt that the concentric circles are part of the lens design.

Yes I too believe that happy patients with them don’t post.  Only reason I post is because I came here on the forums prior to my surgery.  And although I am happy with them I know not everyone is.

i am here for same reason.I worried prior to surgery and read everything.I had a recent  App store app update on technis site.My dr gave me the first one.on multifocals simulationa distinct circle around lights which seems more that what i see with symfony and shown in their simulation.Edge of a light is not distinct but again with cataracts they were kind of a mess with the cataract distorting tail lights into red webs.

Interesting that unless dr has had cataract surgery he cannot exactly know what we see.It really is hard for me to really notice halos or blur around lights unless i make an effort..He asked me my opinion of lens and i said i loved it but am quite easy going.I would never recommend it to my husband who would be quick to find its short comings.I love the range of bright clarity though the loss of contrast in dim light means tiny print can fade without good light.So for me i walk closer to the window to increase light into eye.Small sacrifice for me

Simulator results depend on the computer software behind those. So, it is just like the old saying, " Garbage In ; Garbage Out:"

If the manufacturer does not want one to know about the multiple circles, there is no reason for them to program that effect in the simulator. There is no financial incentive for them to tell the whole truth.

Yes I recall reading that last year and posting.  Some weighed at the that time saying the study had too few sample size and those that received Symfony vs other lenses were much older .

I do think Symfony provides great daytime vision - better range than a monofocal.  The night time concentric circles aren’t mentioned in any study I am aware of and by now there should be.  At the very least the surgeons should be noting that with their prospective patients so that they can make an informed decision.  It I still really a matter of preference to the patient which trade-off they want.  Even though a good percentage of patients will be glasses free as I am it is not something surgeons can guarantee. There are variables they cannot control.  Then there are personality traits that would make Symfony less desirable to some patients vs others.  And I bet some would find fault with every lens - and they will have a harder time living with any trade-off.  But as one ages compromises are a must with many things.

Ha ha - too true.  Totally agree.  Money is a powerful incentive.  

Likely if the whole truth were told to the patient some would still opt for Symfony and others would not.   This is a hard decision as it is a decision of choosing which would you rather live with and the answer isn’t the same for everyone.  However the frustration is greater when one feels mislead by promises and misinformation.

I was never fooled by anyone.I knew exactly what happens with the rings in lens allowing extended range of vision.My dr explained it and I wanted as normal vision as possible and no glasses.The latest technic update shows both multi focal a d symfony evfe ts at night.

my dr said no perfect lens is invented to replace the natural eye..they try and if you watch the eyetube convention coverage acheiving best possible results is a main goal of reputable surgeons.Not fooling people.Did you have a first rate surgeon?

I did learn from my dr who is also a cornea specialist how importand cornea health is..Dry Eye is worth researching on youtube..It is a real entity which i has thought was unimportant..

Interesting.  The halos (concentric circles I see) are very distinct- not fuzzy at all.  The inner rings are brighter than the outer rings .

I would say as a patient same is true - difficult to compare what I have as someone one has monofocals as there is no way to try out both options.  

I regret having to have cataracts at 53.  But my eyesight was getting very poor and driving that way was a danger to others as well as myself so really no other option but surgery.  I am glad it all worked out well - better than what I was anticipating.  A book I read a while ago defined happiness as : Expectations divided by Reality so by that equation I am pleased/happy with outcome.

be sure to read about Dry Eye  ...no way had i thought it mattered much.You tube and the eyetube discussions i watched are really into itcalled Ocular Surface Disease!

You are young for cataract surgery so it probably has not hit you yet!It is said to i tervere with best results for many older people.

Yes fortunately don’t experience dry eye much.  I take flaxseed oil supplements every day (omega 3 would do well too).  Sometimes when I am on computer a lot or using spreadsheets the Systane drops are helpful.

a recent well done study ended up showing fiah oils and omega 3s did nothing much..tnink it was on Science Daily a reputable site for all things science...seems an oil film secretion helps keep tears from breaking up fast, and not evaporate...not blinking due to avid reading not good either.Just keep it in mind...I miss Softwaredeveloper.....now rhere was a man who researched!

when i type on this site i can only  see the line i am writing so miss typos...

 I do not find it user friendly at all

Hello, I'm glad to hear things are working out for you.  I recently picked up the glasses and they definitely help with distance vision.    I haven't been out much at night yet, but my initial impression is that there is little reduction in glare / halo.  I will be driving this evening so I'll see how that goes.

I have another appointment this Friday to discuss the results and how we are going to proceed.

 

Hi m22031

Unfortunately I don’t think night vision glasses do much for glare and halos driving at night.  If the glasses are to correct vision they likely will help with seeing to read road signs etc but not sure they help with glare and halos.

1. My surgeon was excellent. No one could have done any better job.

2. The surgeon is not to be blamed for my being surprised by seeing the multiple circles around lights at night. The fault lay completely on the  Symfony manufacturer, Abbott, and the surgeons paid by them for running the trial lens, who never mentioned the unique types of annoying circles seen by the Symfony users before the effects started being discussed on forums like this. All they talked about how Symfony lens is not only the best choice after cataract surgeries, but also a good choice for getting rid of the reading glasses due to presbyopia..

3. I have not read anything put out by the Symfony manufacturer, which talks about the persons eye characteristics which may control the degree to which they may see multiple circles around lights at night. I know that people on this forum have come up with a reasonable conjecture that people with smaller pupil size may have less of a chance of seeing the multiple circles. But I have not seen any effort by the Symfony manufacturer to tell the surgeons as to what they should look for in recommending the Symfony lens.

4. If the Surgeon or the Symfony lens manufacturer wants to suggest that anyone not willing to or be able to live with bad night time vision should not use Symfony lens, let them be open about it instead of just criticizing the patient after the fact.

5. The bottom line is all the lenses do have pros and cons. It is good to understand those with the help of a good surgeon before the surgery and select the lens which provides the best compromise for the patient. However, that requires that the information on the pros and cons of the lenses be easily available and not significantly biased. Unfortunately, Abbott (now bought by Johnson & Johnson) seems to have failed in providing such good information for the Symfony lens

 

I went to the simulation on the web site and  is rubbish or just not true

My experience and from what i read so far from others that the Symphony  torics extended focus is exactly as what they show for normal multi-focal on the simulation not  for the extended focus

Sue or any one !?

has any one experienced a vision similar or  same as what they show on the simulation for the extended focus Symphony ?????

Agreed, I think Abbott did everything they could to hide the issues. If you look at their simulator and literature you would conclude that it offers the best range of vision with no more problems than other IOLs so why wouldn't you choose them?  My doctor made no mention of the rings and didn't do any personality screening and my cataracts had just started and vision was good which was why this has been so difficult to deal with.  I just assumed since it had been approved and used in Europe for some time before it came here that these issues would have surfaced by then so I wonder if patients there experienced the same things or is it such a small percentage that it just doesn't get the attention it deserves compared to all the people that apparently don't have problems with them.

Hi vlad873 - I would say that for the simulation of glare around lights it is accurate.  What is missing (and therefore inaccurate portrayal) are the multiple concentric rings that one sees around various light sources like red traffic lights with Symfony lenses.

John56935 - in your case if your cataracts did not yet affect your vision violated his oath to first do no harm.  No one should be advised to have cataract surgery if there vision is fine or can be corrected with glasses or contact lenses.  Just plain wrong.  

I would tend to agree with you but there isn't much of a recourse as there was no way to prove that it was done unnecessarily, so as a warning to others always get a second or third opinion on cataracts.  While there may have been a cataract that was starting, it was done prematurely so I probably would have had to deal with it maybe in 5 years anyway so that helps me deal with what happened.  I am waiting until the one in my other eye so bad enough that it will feel like even a symfony will be an improvement even with the rings, and I would recommend everyone wait as long as they can too!

In my case, with one Symfony implant in one eye and one natural eye, the simulator isn't even close to what I'm seeing. The haloes I see are much worse than what the simulator shows.

I do not know how old or how recent is this TECNIS Symfony ZXR product literature? It not only mentions but also has a bar chart comparing the percentage of patients with "halos", "night glare" and "starbursts".  Source: precisionlens net

"Night glare" and "starbursts" generally result from PCO, refractive error (eg. astigmatism), optical aberrations, and/or problems with tear film or ocular surface.  "Halos" relate to optic design and the amount of add power determines the size of the halo.  Source: crstoday com

Presumably those having night vision issues are referring to "night glare" and "starburst", whereas "halos" are concentric circles to some.

A UK blogger has posted his IOLs experience online, complete with graphic images of the glare and halo effects at night as seen through his "Restor" right eye and his "Symfony" left eye. The circles seen through his "Symfony" eye, have a slight flat edge which may indicate astigmatism. Another interesting info: his partner has shallow eyeballs, therefore she can have a pair of Symfony lenses in both eyes.

John - was it your regular optometrist that detected the early stage cataract and referred you to the opthamologist/surgeon?  Usually the optometrist only makes that referral if he or she notes it is a cataract they cannot correct with glasses.  

optometrist said I had the beginning of a cataract but within 6 months it seemed like that eye was slightly blurry so I went on my own to an opthamologist and he just said right away I needed surgery--no inquiry about my history or to see if a new Rx could fix it.  It qualified for coverage by insurance so I figured it was a fast growing PSC and so why wait.  Like I said, I should have gotten a second opinion but was exhausted from fighting other health issues so just trust this guy after checking him out and getting a referral from a friend who used him for his cataracts.  I went back to him multiple times with my concerns and instead of saying to wait which was what most good doctors would have said, he assured me how much better my vision would be. It seems like this happens all to often unfortunately as some doctors don't want to lose the business by having you wait or go to another doctor.  I now treat doctors much the same way as car salesmen, repair people and others who are more interested in making the sale rather than what is best for the patient/customer--caveat emptor!  At least I finally think I have found an opthamologist who I can trust and will use to eventually do the other eye when it is necessary.

That is unfortunate- especially as we tend to put a lot of faith in the profession.  But things are changing and likely many are motivated by profit now.  However if you qualified to be covered under national health insurance (here in Canada it means eyesight 20/40 or worse which I was) the second opinion may have been to have surgery anyways.  The surgeons have submit those tests along with their comments to have the surgery covered.   I know for myself my vision was blurry - so much so reading the license plate on car in front of me at a red light was difficult in broad daylight.  Loss of contrast due to cataracts was worse at night so I really felt driving was unsafe for others and myself.

Also if one waits too long and cataracts are very dense the surgery is more involved.   

All to say don’t berate yourself too much as it may have been a necessary surgery sooner than you thought.  From one year to the next at my optometrist I went from no mention of cataracts to needing it at 53.

Some people choose this procedure to be glasses free - that I have a harder time with knowing what we all know on these forums.  And doctors more and more are offering it as a solution for presbyopia.

At the very least you are heading into 2nd surgery much more informed and armed with information.  Best of luck to you.

perfection not yet here.I do doubt greed is what motivates both companies and the surgeons to “trick” people into edof lenses..The very design is what gives halos as the pupil opens up in tne dark.. My reading shows not all that many edof and  multifocal are implanted routinely. My dr only uses them by request and with description of the effect at night.As i mentioned he is also into the cornea and its health as to outcome

Quite often it is an elderly group which does not drive all that much at night.In tne US only monofocals are covered by medicare.Further eye issues such as macular degeneration and ofher retina issues are easier to visualize thru monofocals.

Still a pleasure to see  near and far without a thought..

 

Begs the question though if implanted young with EDOF lenses there is no way to know who will end up with future eye problems.  

hi john56935, so sorry of your difficult recovery. Sue.An is right about waiting too long. When my bad eye was impacted with cataract, I had no way of knowing it until after I went blind. During surgery to remove the dense cataract, the eye-surgeon lost his temper because I was moving that made it even harder for him.

I just accessed the simulator on the web site, and I would be absolutely thrilled if my night vision was like what is shown.   For me, the concentric circles may be there, but they are not visible because of giant bright starbursts.    For example, with an overhead streetlight, the diameter of the starburst would fill a standard highway traffic lane.   Starbursts around car headlights fill the entire traffic lane and extend into adjacent lanes. 

Do you have a link to the UK blogger?  I am looking for a visual representation of what I'm seeing at night to share with my doctor.

The blogger was a hyperope.  After his RLEs and YAG on both eyes and laser enhancement on his "Restor' right eye, he is pleased with the results. Derek has already left a message there.

@dennis39810, all the best on your surgery on the 17th ~ 3 more days to go.  I've msged you the link as well; perhaps you can come up with better graphic images for future edifying discussions.

msg Link to Sue.An, at201, m22031,  nighthawk, sok.

Thanks i agree that is the HALO effect. which is shown on the multi focal type Symphony  simulation . Which is more or less what i experience.  Concentric circles, actually the glare is almost next to nothing in my case 

If you are looking at the normal multi-focal simulation that is what i see now,(not the extended focus one)    I had the same huge starburst in the begging it reduced quite a bit after a few weeks. And after the doctor corrected the Astigmatism with LASIK in my dominant eye now the starbursts and glare are very minimum not bordering. But the HALO the circles around not much of a change apart is not so bordering

i was watching  dr.mark packer talk on glare and halos.It was at rhe wash dc meeting of the academy of refractive surgeons.They developed a sorr if articical eye /camera where they were able to add either a multifocL/EDOF OR MONOFOCAL LENS.THEY THEN DROVE THIS CAMERA AT NIGHT.THE POINT BEING SURGEONS DO NOT HAVE THE ACTUAL VISION OF THE PATIENT AND THUS NEED A BETTER WAY OF SEEING WHAT THEY SEE.

IF TOU CAN HUNT DOWN THE EYETUBE INTERVIEWS YOU CAN SEE HOW SOME CONTRAST IS LOST AT NIGHT WITH THE WAY HEADLIGHT AFFECT WHAT A PAIENT SEES.THUS A BETTER DISCUSSION OF THE MINUS SIDE OF MULTIFOCALS LONG WITH THE VIRTUES.

HE POINTED OUT THERE MAY BE A NEED TO CONCENTRATE MORE MORE  WHILE NIGHT DRIVING BUT  IT WAS STILL SAFE.OF  COURSE THE PLUS SIDE IS THAT FOR JUST ABOUT EVERYTHING ELSE GLASSES ARE NO LONGER  NEEDED

True about needing to concentrate more when night driving.  Some people need to concentrate more on their day driving lol.  Too much texting and driving these days.

This is a really hard forum set up.I just reread my post full of typos as cannot find any lines i wrote except current one.

Hunt down dr mark packer.He has quite a hair style!
