UPDATES + Preliminary verdict on Mini Mono-Vision.
Posted , 16 users are following.
20th Nov. 2019.
.
I have got few PMs about people wanting to go with the same mini monovision choice as my wife. Instead of replying privately I thought it would be more beneficial posting here to help others in the future. This thread and updated opinion supersedes everything I might have said in any previous thread!!!!
.
Lens Used: Zeiss Asphina 509 Aspheric Monofocal (non Toric as astigmatism was negligible -.25 and -.50)
Surgeon used: Dr Zeiss (I love giving nicknames)
Rejected Surgeons: Dr Headstand, Dr Rockstar, Dr Career and Dr Oldstar (did not meet him though).
Left Eye operated: End of September 2019
Right Eye Operated: End of October 2019
Left eye target was:-1.25
Right Eye target was: -0.25 (dominant eye)
Time between first sign/diagnosis of Posterior Subcapsular Cataract and going virtually blind: 3-4 months!!!!!!!!
Wife: Early 40s, extremely active and had perfect vision without glasses (although cataract probably started forming 1+ year ago and we were just not aware)
.
Question 1- Why did we pick those targets?
.
Answer 1- Without benefit of hindsight. After days/weeks/months of torture the conclusion was that an error of 0.5 diopter could occur in either direction. Could be more if you end up unlucky or lucky depending on final results. So -0.25 far eye could end up anywhere from -0.75 to +0.25 and the near -1.25 eye could end up anywhere from -1.75 to -0.75.
.
We were tempted to go with -1.65 for near eye but it seemed too risky in case it ended up at -2.15 or more and if the far eye went in opposite direction and ended at +0.25. That would have been a potential difference of 2.75 diopter!!!! Greater than 1.5 diopter difference is considered risky as lot of people can't adapt to it. Also the blend zone between the two eyes decreases.
.
My wife had never worn glasses so we had no clue what it all meant in real world scenario. We could not even test anything realistically as her cataract progressed so fast! So -1.25 & -0.25 = difference of 1 Diopter seemed like a safer choice. We could have gone even more safe, for example both eyes to -0.25 or micro mini monovision.
.
Question 2- Why did we pick Zeiss Asphina IOL?
.
Answer 2- Well Zeiss is reputable brand and synonymous with quality and has been around for long time. I knew them from their excellent camera lenses. Then the surgeon we picked, Dr Zeiss recommended them and uses them. The only thing holding me back was that it apparently does not prevent PCO. Dr Zeiss said that as most patients specially young patients will get PCO irrespective of lens choice so that should not even be a factor. Also I saw online that people who went with anti PCO marketed IOLs still got it super fast and in addition had more issue from the anti PCO IOL sharp square edge causing glare etc.
.
The Zeiss square haptic was appealing too. More stable and with less exposed edges. Also it seems to have less issues with glistening. The pure Acrylic hydro phobic IOLs seem to have more glistening related issues and I think micro cracks when injected. Zeiss has hydrophobic surface coating only but internally it is hopefully less prone to vision effecting glistening etc. Fingers crossed for next 50 years! lol
Dr Zeiss said that since he switched 100% to Zeiss IOLs his refractive error surprises have virtually disappeared.
.
Question 3: Why did you not go with Multifocal IOLs?
.
Answer 3: It was NOT an easy decision but with benefit of hindsight it seems to have been the right decision FOR US! Our research and logical analysis pointed us to mini-monovision. Towards the end emotion and fear played a part and we were tempted towards At Lisa Trifocal. Specially when a user here scared us by saying that my poor wife won't be able to see her face/food/read and be permanently dependent on glasses. Luckily calm head prevailed and Dr Zeiss also said to go with Mini-Monovision even though he is expert at installing AT Lisa/AT Lara and would have made $5000 more.
.
EDOF we rejected as Dr Zeiss said that the results he was getting with them he had been getting with Monofocals for 10+ years. Initially he had got taken in with EDOF marketing and their lab test results.
.
Other surgeons said same. If you want highest quality vision then don't go with EDOF/Trifocal etc.
-Monofocals more future proof to future eye health issues. We had to think about next 50 years and not just short term of next few years.
-Monofocals have possibility of add on lenses if required. Constantly evolving tech. Add on lenses much easier to add and replace.
-Monofocals still have option to use Multifocal contact lenses if required.
-Monofocals have less side effects.
-Mini Monovision adaption time few days to couple of weeks unlike months or never with multifocals.
-Monofocals have way less contrast loss.
-Monofocals require less brain gymnastics.
-Monofocals have better low light vision.
-Monofocals have no rings constantly or semi constantly visible.
-Mulifocals have no guarantee of being glasses free without add on Lasik surgery.
-We did not want to touch the cornea for corrective Lasik surgery.
-You can end up glasses free with mini monovison too and that was our aim as we are a very active couple. It seems like wife will be glasses free as things stand. For us using glasses was not end of the world anyway. Only for sports it would have been complicated but already she is doing sports without glasses.
.
Question 4 - Finally, where did you end up and what are your real life results.
.
Answer 4-
.
Left Near Eye:
Near eye seems to have ended up at -1.75 ( to be confirmed at next appointment). It seems to have stayed stable there since day 7 (today is day 54). With benefit of hind sight, if we had hit the target of -1.25 then wife would definitely not have been happy as reading etc without glasses would have been an issue. So we got lucky for once!!!
.
My wife currently requires no glasses for PC, mobile phone, laptop, writing reading, eating, cooking, watching TV....she can see herself super sharp in the mirror too. She has been working 8+ hours a day for last 1 month at the office without requiring any glasses. No headaches either although she did have it for first few days when brain was adapting.
.
She can read J1 in all real life lighting conditions. Sweet spot is at 45cm/17in but can read at 35cm/13in too . Usable vision 35cm/13in to 2.5m/98in. For example she can see electronic alarm clock in the bedroom 2.5m /98in away. I feel anything closer than 30cm/11in is wasted diopter so the lowest I would ever go with near eye is -2.0. You do risk then ending up at -2.5.
.
Far Right Eye:
.
Far eye was targeted for -0.25. This eye has taken or is still taking lot longer to heal unlike the left eye. We don't know where it has landed. We entered week #4 now (Day 26) so still not fully stable as we have to wait 6 weeks. We are seeing Dr Zeiss end of this month so will know the real number. The reading we had were +0.25 then -0.25 but these are very old readings. So we could be at -0.75 or -0.5 or even -0.25 currently. No clue!
.
On Snellen Eye test chart she now seems to have 20/20 in lock down (1.0). Yesterday she was hitting perfectly two lines below the 20/20 line, I think line No.10 is 20/12.5(1.6). With this far eye she can read close too!!!! J1 at 60cm/23in. Can read even closer than that but sharpness decreases.
.
So it is difficult to guess where she is currently. Her really far vision is not always super sharp yet, it keeps changing from one day to the next. Drops make it super sharp. So could be healing and dry eyes related. The swing is getting narrower though. It is amazing that she started at 20/200 after OP!!!!! Took 3 weeks to get to 20/20 and looks like maybe some more healing still to come!
.
Side Note-
At one point my wife's near eye was at -2.0 and far eye at +0.25. So a difference of 2.25 Diopters. She loved that too and we could not detect any loss of binocularity in real world usage. Obviously someone else in similar situation might not have been able to adapt. Psychologically it was scary knowing that the difference was 2.25 though.
.
PCO status-
Left eye 1 day post OP- Had remnants of lens cells. I guess polishing the capsule more would have been risky for that capsule. Intact capsule is very important for younger active patients.
Right eye 1 day post OP- Capsule was crystal clear.
.
IOL Edge issues-
No lens issues as such. My wife's left pupil at 6.25mm is larger than the IOL middle part at 6mm. In very dark situations when pupil is fully dialated she sometimes can see slight IOL edge. She kind of enjoys it and says that the Zeiss Asphina is saying HELLO to her 😃 When we walk on a dark street she always say "Come on Asphina, say hello or are you going to be shy again and hide" lol
.
No glare, starburst , halo or edge light bounce issues though.
.
Recovery-
This varies a lot too so don't panic! To fully know if the surgery was successful you need to wait 6 weeks.
My wife's first eye took 1 week to be stable despite severe reaction to the disinfectant plus steroid drops. 2nd eye took 3 weeks to get to 20/20 or better vision and still healing even though the reaction was lot less.
.
Overall Conclusion-
Do your research and pick a good surgeon. Follow up care can end up being very important. Dr Zeiss despite being super busy ended up exchanging 17 emails with us and some include funny comments at a time when we were in panic mode! lol
.
He replied within one day to us and 15 of those mails were within 3-4 hours!!!!! In comparison Dr Rockstar took 9 days to answer a simple question. Also most surgeons here operate and then pass you on to someone else, kind of washing their hands off you. Dr Zeiss on the other hand even contacted us twice to check up on our progress.
.
Anyway take everything I have written or what anyone else tells you online with a pinch of salt. Don't let people's personal bias and mental issues swing your decision or scare you.
.
Also some people online are too attached to their IOL and take any valid crit of their IOL as a personal attack. Results can also be very subjective, one person's excellent vision can equate to average vision for someone else.
.
Mini-Monovison is not an answer for everyone. Maybe At Lisa would have given us even better results. I am not close minded to think that our way or the IOL brand/choice was the best way. We don't know and it is something no one can know. If the far vision gets even more sharp then it would be a 100% perfect result. As things stand it is already a very good result, we take the results we got with open arms. The fact that it seems to be glasses free is a very welcome bonus.
.
My personal recommendation for what it is worth, go with Mini Monovison using quality Aspheric Monofocals followed by latest generation Trifocals. Where you target it is something you will have to decide for yourself plus with your surgeon. No two eyes are the same. Even the two eyes on the same person are not same lol
.
**GOOD LUCK!!!!! **
.
I hope this info helps. I will update final numbers and eye condition news after seeing the surgeon in a week.
Lot of people helped me with their time, here and in other forums. THANK YOU!

Thank you for the update. I'm glad your wife is doing so well. All of your posts have been very helpful. I look forward to hearing her final numbers. My prediction is -.25 for the far eye, -1.75 for the intermediate. 😃

Thanks Deb 😉
It's weird that she can read the chart so well sometimes but still far vision is not always sharp. It stays good for few days then not so good for few and so on. It could be healing/dryness related as Dr Hagan told me and we just need to be patient.

Hi W-H,
Thank you for your detailed and comprehensive post recovery update, partly in response to my PM, of your Mini-MonoVision (MMV) experience.
As you know I've just got on the Cataract Correction Roller Coaster so have a couple of queries.
You mention your wife can see well to 2.5M. How is her visual acuity from >2.5M to < ∞. I have a flat screen TV at around 3M and wall hangings etc. at 4M-6M and drive a car so I hope that I will be able see these distances clearly and read TV text, street signs etc. after having a similar MMV procedure?
What is meant by 'seems to have 20/20 in lock down (1.0)'?
Dr's Rockstar and Zeiss I get, but Dr Headstand? 😉
Regards,
Don D
BTW: I’ve just nicknamed my first two Ophthalmologists in honour of your precedent! They are Prof. Reticent and A/Prof Impatient! Wonder what Dr. #3 monicker will be when I see him in Dec? I'm hoping for a Dr Zeiss V2.0! 😃

Don which country are you from? Using meter as units? I am so happy lol
.
A1- Roughly 35cm to 2.5m is the vision from the left eye ONLY. I just measured the 2 spots from which she watches our large flat screen TV. 1st spot is 3.3m away and second spot is 2.7m away. From 2.7m spot she sees it better, again with left eye ONLY. The vision is not sharp enough to read text on the screen.
.
2.5M to < ∞ with left eye is blurry. You are not going to get sharp vision from the eye set for near. You still see stuff but it is not sharp.
.
You see the chart below? So the IOL has a bell curve. At the peak you have sharpest vision. Then 1 diopter on each side vision starts to drop off to blurry. So at peak is most usable then gradually less.
.
.
When you have both eyes done. In my wife's case the right eye was set for far. So now she can watch TV from anywhere in the room and she sees super sharp ALWAYS, small text on screen etc. The info from the left eye (even inferior info) gets combined with the info from the right eye (superior info). Brain does it's combining gymnastics 😃 Inside the flat she sees super sharp EVERWHERE!
.
A2- We are talking right far eye vision. The Snellen Eye Test Chart is used to measure far vision. For left near eye you use a different Jager eye test card/chart.
.
So by lockdown I meant that she can see 20/20 always on the Snellen Eye Test chart with her right/far eye... 20/20 vision on the chart is in the bag. Just an expression.
.
When she started measuring after the operation. She could read only 20/200. Then it got better and it would keep fluctuating anywhere between 20/80 and 20/50. Then it got more better and it would fluctuate between 20/40 and 20/25 for a long time. And recently it has started fluctuating between 20/20 and 20/12.5. Meaning that at least 20/20 she is always able to read, both with or without eye drops.
.
I am not from USA but they use that 20/20 expression. Here in Europe they use the decimal notation.
.
So for example I have 20/10, 2.0 or 200% vision. My eye doc's electronic chart had 1.6/160% as the smallest number so that is what she wrote on my file. Normal people have 20/20 vision.

Btw Dr Zeiss on our first visit was Dr Eyes Closed lol He went on to give us a long talk on auto pilot with his eyes closed. My wife was sitting on the eye check up chair and I was sitting on a lounge partition thing right next to it. The lounge area had like a 1m wall to separate examination area from anyone who accompanies the patient area.
.
We already knew what he was telling us but we were not able to interrupt him. That wall on the first visit felt 10m high. Me an my wife looked at each other in disbelief multiple times. It was like a scene from a comedy movie. Finally he stopped and we could kind of talk.
.
We felt that he was passionate about his work. Still we were conflicted about him and Dr Rockstar, we could not decide. We did not have enough data to judge Dr Eyes Closed. So we visited him again and he got promoted to Dr Zeiss (Dr Passionate was reserve name). We went with our gut but still feared in case we had made the wrong decision. Now we know it was the right decision. His receptionists are really nice too.
.
We had Dr Oldstar in reserve. An aging doctor so we were not sure how shaky his hands would be 😃

Love the nicknames! There are some that get far more usable range than others with monofocals both targeted for distance. Who and why is anybody's guess including the surgeons.
Just put some thought into what your preferred targets are. If being glasses free to drive personally I would target dominant eye for near plano.
Good luck and look forward to your posts.
Deb03 DonDiopter

Agree with SueAn on targetting near plano if you want good distance vision for driving. My LE is +.25 and RE is -.25S -.25C. Everyone's eyes are different, but with my RE only, I'd need glasses to drive. And I still prefer glasses for night time driving. My opinion now that I have one over and one under plano is if I were doing some sort of monovision, I'd rather have it land slightly beyond plano then under plano to get sharp distance.

"I'd rather have it land slightly beyond plano then under plano to get sharp distance." -- the only problem with this argument is that if astigmatism were present then distance would still remain blurry.
Deb03 soks

True and you will lose more intermediate vision so that would be a bummer if you still need distance glasses. But if it's mild astigmatism like I have, you'll probably still see better at plano or just over. Before my RE exchange I was +.5S -.5C, now I am -.25S -.25C. My distance was much better before the exchange. Of course this is my micro-mini-mono eye so that's what I wanted.

There are too many variables Deb. Someone with -0.25 could see sharp in distance and someone with +0.5 might not see sharp in distance. Our eye is amazing, no amount of tech can match the natural eye's abilities.
.
We all got dealt a bad card with cataract, specially the younger ones!
Deb03 W-H

Very true. Everyone's eyes are different and their priorities may be different. I was farsighted my whole life and that's something that's hard for me to give up.
Guest W-H

I agree that there are many variables, and some of them are unknown.
But one variable is very simple, and plays a big role.
When the lens get more and more out of focus, and you drop some lines in the eye test, it plays a big role what your starting point is.
20/20 is considered normal vision, if you have no eye issues, but many have better vision than this.
A person that have 20/20 behind the cataracts, and drops 4 lines because of distance and image gets out of focus, that person will be at 20/50, which is not considered as usable vision at all.
And you with 20/10 as a starting point, if you stand at the same distance and image gets the same amount of defocus, you will drop 4 lines and be at 20/25, which is considered as very usable vision, I have 20/25 at my best eye in best conditions.
If I had 20/10 as a starting point, I would never consider anything other than monofocals 😃
.
And another thing, I have thought about.
I really think it must like this, that the higher the diopter your lens have, the less range you get. I have found no studies to back it up though.
But we all know, that the higher the numbers, the less precise are the measurements and calculations.
I have 29.5 both eyes, if they miss by 2% they miss target with 0.6.
And I have had 10 diopters, 2% miss would only be a miss of 0.2 diopter.
This is all my own thoughts, but if your lens is 10 and you get a range of +1 from a monofocal, you get 10% range.
And if like me the lens is 29.5, then +1 is only 3.4% range.
I think premium lenses are made to compensate for this with the spread they have between the focus points, I think this could also be the reason some have soft spots with the premium lenses and some have not.
I am only guessing here, but anyway, I think it is a good guess 😃

my surgeon was Dr Know it All but my regular optho is Dr Angel. we should all
give our docs nick names. lol

danish your speculations make sense to me

Sure, but there is a thing called royalty payment. Make sure all of you pass $100 to me for each name you give 😃
So Hudson, you owe me $200. Dr Angel was already given to our female eye doc few months ago so you got to pay $200 extra for name infringement 😃

Hi Everyone...
.
We saw Dr Zeiss today.
My wife's far/right eye which was targeted for -0.25 has ended at exactly -0.25 after 1+ month.
.
Left near eye continues to be stable at -1.75 after 2+ months.
.
Right eye's far vision is not always sharp even though wife can read 20/16 or better ALWAYS now. The right eye's cornea has some erosion on it and wife has been put back on Dexafree steroid drops for 2 months!!!
.
He can't guarantee that far far vision will get super sharp but because she sometimes sees far super sharp means that it most likely will get sharp when cornea surface fully heals. Next appointment in 3 months.
.
PCO in both eyes is normal, nothing worth talking about level he said. It can come in 3 months or 3 years. Being young he thinks definitely sooner.
.
All in all was a good day as atleast we have a possible reason for far vision not being super sharp always.
.

Dr. Zeiss nailed it! 😃
But off course we always knew he would 😃
Deb03 W-H

Thanks for the update. So happy she has a great outcome. Hoping the cornea surface problems will resolve soon and her vision will be sharp!
W-H Guest

Yesterday he looked at wife's right eye for ages and kept saying "interesting". Me and my wife were super scared lol We thought something was wrong with the retina, lens etc
Then he finally explained about the cornea surface.
.
He then looked around for things in his drawer for few seconds and finally pulled out a random red coloured plastic sheet. Turned his window blinds off. Then asked wife to cover her left eye and look through right eye only. Then he held the plastic away from his face on his left side and then on his right side while asking my wife to focus on his nose. He asked my wife does she notice any difference in the colour of the plastic sheet. Wife found the sheet lighter on one side and darker on the other side.
.
As the erosion of the cornea surface is on one side of her eye it confirmed to him that vision is being effected.
Hudsongrl W-H

dang... sorry about the corneal erosion. Hope that heals for her. at least her targeted vision came out where you wanted it to.

I understand, off course things would have been better without that issue, but I think Dr. Zeiss have done a great job, I don´t think another surgeon would have payed this much attention.
I hope for your wife it heals up and gets perfect, in any case I would have taken that vision over mine any day, even that I am happy with what I got now, because I realize that I got what is possible from the cards that I have been dealt from natures side.
Your wife have gone from having fast growing cataracts and really poor vision to being glasses free, although not perfect, but quite good vision, that is not holding her back from living her life, and do the things she wants to do.
In my mind I think it is a great result, even things are not perfect 😃

For sure Viking 😉 Yes! no complains about Dr Zeiss! These were things out of his control. If I had to choose a surgeon again, we would pick him definitely.

glad all gas worked out. Brain will continue to adapt and distance could improve.
W-H Sue.An2

Another thing I forgot. We spoke about YAG. Dr Zeiss said that after YAG, 80% of his patients notice 0 refractive difference.
.
In 20% of the cases refractive outcome either gets better or slightly worse due to IOL movement!
.
So for example my wife's -0.25 eye if IOL moves towards plano then far vision will get better, if moves in opposite direction to plano then it will get worse.
.
Lottery!!!!
Sue.An2 W-H

but in terms of an EDOF lens movement would not make my outcome better. 20% seems quite high - doesn't alleviate my concerns.
W-H Sue.An2

No idea Sue. Atleast he was not giving 100% guarantee that nothing will change.
.
Did your IOL hit the target perfectly? Maybe some room for improvement? Unfortunately also possibility of decline!!!!

RE is perfect. Hit plano. zero astigmatism. No correction needed at all. LE does have .75 astigmatism and hit 20/25.
