looks like technis eyhance is awesome. it is giving good intermediate with no rings and glare and halo. the diopter transition seems smooth. why isnt anyone going gaga over it?
it will also have no glare for folks with large pupils. being technis its will also make its way to US/CANADA.

I just read something VERY interesting and important to anyone considering Eyhance. If I'm understanding correctly, autorefractors to measure eye power mostly concentrate on the central part of the eye. But Eyhance uses the periphery of the lens for distance. The central part of the IOL has increased power for intermediate. So if a surgeon relies solely on the autorefractor to choose IOL power you may end up with an over-correction. This would negate any of the promised intermediate vision of the IOL. Instead J&J strongly recommends using a phoropter and the Maximum Plus to Maximum technique to determine the refractive target. The end result may that you may need to target -0.5D for example in order to achieve 20/20 distance with Eyhance! Super interesting and important info. I'm not sure if my explanation here is correct. Its a little confusing. So anyone please feel free to correct my explanation if you understand it better.
.
Search on "Maximum Plus to Maximum Visual Acuity Technique"
.
p.s. Here is the exact text from the J&J Eyhance News Release:
"Precautions: 1. Autorefractors may not provide optimal postoperative refraction of patients with TECNIS Eyhance IOL, model ICB00, lenses. Manual refraction with maximum plus technique is strongly recommended."

that note is for post surgery refraction to see where you ended up and not for iol selection.

Ahh! Haha. Good to know. Still very interesting.

I think what threw me off was when they mentioned not to use an "autorefractor". I've never heard of such a thing and didn't even know such a thing existed (just Googled it). I assumed Autorefractor = IOL Master.
.
So when they say "refracting the patient" they just mean "checking your glasses prescription". Gotcha. And by using the "maximum plus technique" you can wear glasses to fine tune your distance just right (maybe for driving) while still not messing up your intermediate too much even with the glasses on. That's cool.

thats the interesting aspect of the article you shared albeit post operatively. basically u wud decide on distance glasses through trial and error. they have to do that for near as well. autorefractor is only for distance.

If the price is 'right', it's my #1 for the dominant eye, when that time comes.
Symfony is on my non-dominant eye.
the deciding issue is the cost of Eyhance, compared to monofocal IOL (no cost, covered by insurance).
Does any one know how Eyhance is priced yet in the United States, since it's a advanced monofocal lens?

My Eyhance in mono vision:
March 4th - left non-dominate eye -1.34 D (according to Ora) EyHance lens -21.0D
March 18th - right dominate eye +.1D (according to Ora) EyHance lens -18.5D
Right eye (close up eye):
Distance is 20/40.
I can see my computer screen (39inch 4k) very clear from 12 to 36 inches.
I can read my bike speed-o-meter (LCD not backlit) at night with the street lights.
I can now read J1.
I can read the smallest font that can be set on my S10+ cell phone.
I can read the 1/2 unit scale on an insulin syringe.
I can read the content labels on items at the grocery store.
Left eye (distance eye): it has only been ten days and it really has not stabilized yet.
Distance is 20/20.
Television watching is crystal clear.
I can clearly see the dashboard on my car with this eye only.
For the computer it is still a little fuzzy.
YMMV, but I am very happy with my Eyhance mono vision.

isnt the -1.34 your near eye? and +0.1 your far eye?

With both eyes together in mono vision I can see everything that I want to see.

Yes. I typed that wrong but the site wouldn't let me fix it.
March 4th - Right non-dominate Close Up eye -1.34 D (according to Ora) EyHance lens -21.0D
March 18th - Left dominate Distance eye +.1D (according to Ora) EyHance lens -18.5D

Can you see computer screen (24 inch 1080P) very clear from 24 to 28 inches by left eye (distance eye) ?
I will going to get Eyhance in one eye next month.You experience will by very helpful to me. Thank you.

My left distance eye really has not stabilized yet so like I said the computer screen is a little fuzzy at the moment using just that eye. A few days ago the car dashboard was fuzzy too, but not now. Keep in mind with both eyes all is clear.
A friend of mine got a plain bi-lateral mono focals set for distance months ago and he told me that he can use the computer without glasses but it is better with glasses. Considering my near eye results I am expecting better intermediate vision with the distant eye than he has, but cannot say I am there yet. Although it might not be a valid comparison because I am comparing my one (right eye shut) to him using both eyes for his computer vision.

OMG yes the forum software on this site is absolutely brutal. The threading makes it impossible to find the most recent posts. And the editor is a disaster. It completely takes over any native spellchecking or editing features in iOS or probably whatever OS you're using. And the "memorable word" thing for login is probably the #1 worst UX crime I have ever seen for a site login. Unreal. Absolutely the worst forum I've ever used in 27 years on the Internet. Usenet blows this junk away. But it's loaded with great info and other people sharing their experiences... so I guess we have to deal with it.

Hey Rabbit!
Im really interested in your result, as I'm interested in Eyhance for monovision as well. My one question(which I know I should ask my surgeon) how do they target the near eye? With the distance eye set for plano, of course you just hope to get the most "reach" back into the intermediate zone. For the near eye, I am guessing they dont set it as near as they normally would, because they're counting on the Eyhance "reaching back" and giving the desired near distance, that was its not "too far back" and you benefit from some blended intermediate vision? If that makes any sense at all. Were you your surgeons first Eyhance monovision case?

For the near eye I had the advantage of an Optometrist brother and Ophthalmologist friend that both said it was smart to go for -1.25. That along with the experience of Eduard3602 here that seemed to have that same needs as myself. The surgeon from Austria that said he has done a few thousand EyHances also mentioned going for -1.25D if you really wanted to see good up close. Also the J & J blended vision diagram looked pretty good to me too:
I was wanting to go with -1.5D but my brother insisted that we should target 1.25D. If I had gotten my way it probably would have ended up about -1.6D or higher. I am not sure I would have as good of computer vision and that is what my brother kept telling me and he was right.
Of course it did not end up exactly at 1.25D but I am as happy as I could be with the results of my near eye. I am still waiting for my distant eye to stabilize. That was the cataract from hell that was described as a rock during the surgery.
I am sure that my result would not be so good if I had not paid for the ORA system. The Ora system changed the lens choice each time. On the distant eye the pre-surgery numbers said use a 19 lens and the Ora said an 18.5. Although this eye isn't stabilized yet I am guessing/thinking it is going to end up on the near side of plano. The 19 lens would have put that much more on the near side. Time will tell.
Yes I was their first EyHance case. I talked to the J&J rep this week and she said I was the first bi-lateral EyHance in the State of Michigan.

Hey thanks so much for the reply. I was curious because I noticed you mentioned in another comment that you have sharp vision at 12 inches. Do you mean legible reading, or actually sharp text? I have Tecnis monofocals in both eyes, both at roughly -1.25D and my sharpest vision is at 18 inches, closer than that I start losing clarity rapidly. I'm wondering if the Eyhance is giving you that extra 6 inches, because if so that is amazing. As for the chart, I don't believe it is from J&J, it looks like an advertisement from Zeiss Presbyond Lasik that I think an eye clinic edited to explain monovision with Eyhance, however I think it does the job well. I am currently considering exchanging my dominant eye for an Eyhance at plano for monovision, I think it really has the chance to give me a seamless range of vision without the side effects of a multifocal or EDOF. I made a long post about my situation recently if you're interested, but its really great to read your story because you've achieved what I hope to with a lens exchange.

I think what I wrote earlier about 12 inches was about seeing the computer screen and that is true. However seeing a brightly lit screen is completely different thing then say reading text on a piece of paper.
So in front of me I am holding a printed 8 1/2 x 11 letter with text that looks to be a 10 or 12 pt font.
At 12 inches I can read the text just fine and it is clear.
At 13 or 14 inches it is still clear but somehow feels more comfortable.
Holding it out as far as my arm can reach I can still clearly read the text which is probably about 28 inches. When my bros the optometrist did this exercise the other day he held the paper out at 30 inches and I could still read it fine.
Before I had surgery I watched a video that I think was the surgeon from Austria that talked about EyHance and how some people could see very good close up and some not as good. And I think that was people with -.50D mono vision? Anyway, they could not explain why that was. That's why I say YMMV.
I still cannot say much about my distance eye. Today while driving the distance vision was not so good. I put on my old glasses and the distance vision sharpened. Just now I drove home at night and I could see in the distance just fine and when I put on the same glasses it got a little worse. The only thing that is consistently clear with this eye is watching television. Time will tell.

Now it has been six weeks since my last eye surgery:
Right eye (close up eye):
Distance is 20/40.
I can see my computer screen (39inch 4k) very clear from 12 to 36 inches.
I can read my bike speed-o-meter (LCD not backlit) at night with the street lights.
I can read J1 text on my close up vision
I can read the smallest font that can be set on my S10+ cell phone.
I can read the 1/2 unit scale on an insulin syringe.
I can read the content labels on items at the grocery store.
I can read 10 or 12 pt text on a piece of paper at 12 inches out to arms length
Left eye (distance eye):
Distance is 20/15- or 20/20+. (read the 20/15 line but missed a letter)
I can see my computer screen (39inch 4k) at ~24inches almost as good as my close up eye but fuzzes out closer.
Text on a plain piece of paper that is not lit up like my computer screen is not clear at an arms distance. I can read it but not so clear.
I can clearly see the dashboard on my car
I could use the cell phone only with an increased font size.
Overall:
With both eyes together I am about as good as it gets for a sixty something year old. Especially the overlapping good vision with both eyes at~24 inches on the computer is very nice. ** And of course NO ARTIFACTS... I have no halos, starbursts, rings, or whatever.
Now after saying that, all is not perfect because dry eye issues are causing inconsistencies and especially with my distant eye seeing street signs while driving. I find myself blinking a lot to see the signs clearly. I have been on Restasis for over a year but the dry eye is still a problem. Driving glasses that bring up my close eye for distance should take care of the problem. I do not drive much anyway and the problem seems unnoticeable while bike riding.

you have been very helpful to me. I am scheduled to do just what you did with eyhance. R eye dominant distance and L eye intermediate to near. (which by the way is what my natural eyes are also, but now with cataracts)
If my results are close to yours I will be one happy lady. Thanks so much for posting here.
