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 noted this in my new discussion regarding PanOptix v Synergy. (See new Shannon Wong video.) My friend just had toric Eyhance lenses implanted and she says she is "over the moon with joy" about her results. She did recently purchase 1.25 readers for very small print or long periods of reading, but she is otherwise glasses free. The quality of her vision is excellent. She has not yet driven at night, but Eyhance is a monofocal. Nighttime problems are not anticipsted.

i think vivity is better than eyhance.

I have had Eyhance lens implanted in both eyes for ~6 months. The vision is clear at the focal length of my eye plus lens combination. Both eyes are ~0.5 diopters near-sighted so I see clearest at about 6-7 feet. Distance vision is somewhat blurry, but I usually see good enough to drive confidently without glasses. However, at night, I see a starburst pattern from lights (such as street lights or car headlights). If I use Alphagan eye drops to reduce the size of my pupils, the problem goes away, so I assume these artifacts have something to do with large pupils, edge effects, or effects from the outer aspheric lens surface. In the daytime, I also see reflections in the lens from overhead lights, although this is much less annoying than the streaks off of lights at night. Has any other patients with Eyhance implanted noticed these type streak and reflection artifacts? I'm considering having the Eyhance lenses removed and replaced with standard monofocal lenses. Has anyone out there taken this step?

Hi Karen. Thank you for your description of Eyhance I been considering it. Your real experience helps and sending out Blessings for best vision ever. With Eyhance did you choose distance or near like traditional monofocal? Or is Eyhance more like multifocal where you do not choose?
Your experience is distance vision blurry? I thought Eyhance enables good vision distance and intermediate. From reading this excellent forum I have not yet read about patients with Eyhance noticing streaks and artifacts. What makes you consider removing Eyhance for standard monofocal? Your post is such a great current observation. Thank you for posting

eyhance are not monofocal in true sense. the thickness of the lens varies to allow for more accommodation. thats why standard monofocal could be better than eyhance.

I have Tecnis Eyhance in my right eye. It
s 5 weeks after surgery. My eye is -0.75 and vision is blurry in every distance. Double vision and blurry. Close, intermediate and far. I have worse close vision than a person with monofocal. I cant read smartfon, laptop screen. I dont know, maybe it will improve, maybe its because of dry eye after surgery. I will wait 6 months before making any decision regarding to my left eye. Or maybe I should remove this Eyhance. I dont really know.john20510 soks

So if you are going to go with monofocal lens only and monofocal disatance would Eyhance be the best monofocal lens to go with?

i would go with clareon vivity if and when it is available. one set of -0,75 and other set for plano.

If you are impatient you could go with a Clareon Monofocal (plano) in your dominant eye now, and then Clareon Vivity (-0.75 to -1.0) in the non dominant eye when it becomes available.

it is difficult to say how much near one gets with a monofocal. some get great near and some get it starting at 3-5 feet.
if i went with monofocal i would set it at -0.75 and then wear glasses for astigmatism and -0.75 sphere.
also i think clareon pan optix will arrive before clareon vivity.

I think the critical part of getting near vision with a monofocal is accuracy the of the power selection. You cannot go to the + side, or start to lose both distance and close vision. Better to error to the - side as it will cost a bit on distance, but you gain on close vision.
.
My thoughts are that if lenses are available it is better to correct astigmatism with a toric IOL. If Alcon offers toric lenses in the Clareon lens in the same powers as the AcrySof, then they have a -1.0 cylinder option which gives about -0.75 D at the eyeglass plane. Astigmatism correction with the IOL gives you benefit with no glasses, rather than requiring glasses.

I had an Eyhance (non-Toric) implanted back in April of 2021 in my right eye with LRI for astigmatism. RX before the surgery was -3.50 -1.25 132.
RX now (February 2022) is +0.75 -1.00 105. The surgeon was targeting plano for sphere, and 0 for cylinder, which quite clearly he missed. My uncorrected vision in this eye is mediocre.
Blurry from 1 ft to about 3 ft, then improves a little but still only 20/40 for distance. Corrected vision is between 20/25 and 20/30 depending on which optometrist tests it. Had YAG done in December, not sure if it improved anything.
Is it reasonable for the surgery to have missed the target by this much for both/either sphere and cylinder? I paid extra for the use of Femptosecond laser and OAR technology, and was hoping for better results than I ended up with.
The interesting thing is the my vision seems better when the ambient light is dim (twilight, evening, or dark) in terms of contrast and sharpness than when it's bright or sunny when everything seems kind of washed out/low contrast.
I've been mildly depressed about the poor outcome since April, I was hoping for A+ outcome, and I feel I ended up with B- results.
Any insights anyone?
Thanks,
Allen

Allen, you are correct in that your outcome is not optimal. Achieving the target is not as easy as one would think with all the technology we have. But, that said you do have a significant miss. The very worst kind of miss is what you have where the outcome goes into the + zone at +0.75. That reduces the vision both near and at distance.
.
Error can be introduced when the eye is measured, and it can be more difficult to get accurate measurements if the cataract is dense. There are differences in the measuring equipment and an IOLMaster 700 is probably as good as it gets especially if the cataract is advanced and more dense. The formula that the surgeon uses is also another source of error. But, with the best equipment and the most suitable formula only about 85% of time is the actual within +/- 0.5 D of the target. It increases to 95% or so if the tolerance window is +/- 1.0 D. For these reasons surgeons should target to be slightly negative and not for 0.0 D plano. If you want to read an article about the accuracy of the various formulas used google this article.

Hi RonAKA, thanks for the article reference, I found it.
So, 85% of cataract patients do better than me (within .5D) .
Can't help but think that I gambled on the wrong surgeon, even though he used Femtosecond laser and ORA technology. My cataract was mild, not very advanced. He never even mentioned to me the options (e.g. targeting -.5D for example), wish I knew that prior.
Any ideas why my operated eye with the Eyhance IOL sees better (sharpness and contrast) in lower light conditions (e.g. twilight or evening) vs. sunlight or well lit rooms when the image seems washed out and lower contrast and sharpness? It's not actually bad, I like seeing better in lower light conditions. My eye surgeon and my optometrist have no explanation.

I am afraid I can't explain the dimmer light improvement in vision. Normally when the light is brighter, the pupil closes down and the range of focus improves.
.
Have you tried a toric contact lens to correct your residual error?
.
There seems to be more issues than just a miss on the power though. Perhaps you should get a second opinion from another surgeon on what is going on.
