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.

Hi, I have read every post in this forum because I have to choose an IOL and I greatly appreciate everyone's experience. I am leaning towards the Eyhance because I do not want to risk any visual discomfort from glare and rings, etc. They say some people tolerate these and other don't, so I don't wish to take that chance. Furthermore, I currently wear progressive glasses and I do not mind continuing to do so.
I think I am similar to Eduard who posted above and I greatly thank him for sharing his experience.
One question I have is whether a standard mono lens which would be ever-so-slightly sharper at best focus, and maybe have better contrast, would be an even better choice? Especially, considering that I do not mind wearing glasses.
But, is the slight reduction in peak focus so small that it is not important? And, could it be improved anyway with distance glasses? (Or is the sharpness gone, once you have a lens implanted?)
And, is the contrast reduction compared with a monofocal IOL, significant or so small noone would notice it? I do attend live theater (after Covid hopefully, that is) and although the stage lights are bright of course, I wonder if losing light is more of a problem for someone who likes to sit in a dark theater.
Any helpful input would be greatly appreciated by me and I'm sure others in a similar situation.
Thank you.

Search on "Delivering Intermediate Vision: The New TECNIS Eyhance Monofocal IOL" for a PDF that answers these question. It's from J&J so maybe take it with a grain of salt… but the data looks great. Actually claims better 5mm pupil contrast sensitivity than the Acrysof monofocal. And identical at 3mm. And peak focus acuity is slightly less but still better than 20/20. Basically it's a monofocal with very close to the same visual quality of a traditional mono but with a slightly bigger sweet spot. That doesn't just mean some potentially usably intermediate vision but probably also a better chance of hitting the desired refractive targets. Kind of like how large modern tennis rackets give you a better chance of hitting the ball well compared to the smaller wood rackets from way back.

If you do not mind wearing progressive glasses I would suggest a monofocal lens in both eyes set for distance is the lowest risk option and will give the best night vision. No lens is going to give you perfect vision, and the progressive lens eyeglasses will correct any residual spherical or cylinder error.

True. Monofocal will always be the best possible vision quality. Especially if you're willing to wear glasses all the time to correct any residual error. The only thing I would say with Eyhance is it's quality seems to be so very close to a Monofocal but the bigger "landing zone" means you have a better chance of hitting your refractive target without glasses. So I think that's going to be my choice personally. My other choice was Vivity but I'm a little concerned about night vision and the loss of contrast sensitivity and I have a very risk-averse personality.

I am having my first eye done this Thursday March 4th, 2021. Two weeks later the 2nd eye.
EyHance in both eyes. Non-dominate eye -1.25 to -1.50.
Using the ORA System™Technology to select the lens at the time of surgery.
A long time friend who happens to be an Ophthalmologist is doing the surgery.
I will post after each settles in.

Good luck! Can't wait to hear how it turns out.

I am interested in the ORA System. It seems to me that it is best to have it since it should only help to improve, or at least confirm, measurements, but do you think it is essential? Should I pick an Ophthalmologist based on whether he has and uses this? I'm have read that it is most important only in cases where patients have previously had Lasik or something like that. I guess those kinds of procedures can obscure the measurements that are normally made pre-surgery. I am looking forward to any posting on your experience after March 4th. I will also post my experience after surgery for the benefit of anyone looking in this forum for personal experience from others.

Just got home with an Ehance in my right eye. Still pretty blurry, bright but blurry.
Before surgery the numbers looked like I would have to choose between -1.1D and -1.47D. But after my lens was removed the Ora System indicated a lens choice of -1.35D, and that is what I did. I assume one of the -1.1D or the -1.47D choices were turned into the 1.35D with the measurements from the Ora system, I am not sure which one. I will have to ask later.
I had no previous Lasik. I just had the money to pay extra for the Ora. I am not even sure how much extra it cost me yet.
Stay tuned.

Just had a post op appointment. My retina is very very swollen. They cataract was pretty hard to get out. At the moment everything is still pretty blurry but I can see 20/40 distance in this eye that was targeted for close up (-1.35D).When the swelling goes down that distance vision may get worse as the close up vision gets better.
It is gonna be a few weeks before I can post any meaningful results.

Thanks for sharing your experience; I hope everything goes well with subsequent healing.

Correction, not retina swollen, cornea swollen. Apparently if one puts off surgery too long the cataract can get harder to get out. The more energy it takes to get the cataract out the more likely swelling occurs.

I had an appointment yesterday. The Ophthalmologist said we hit -1.25D. Glad we used the Ora system otherwise we probably would have missed it by .25D. Before surgery the calculations done indicated lens choices of -1.1D and -1.47D. The J&J rep was advocating to go with the -1.1D lens. With the Ora system it indicated the previous thought to be -1.47D lens was -1.35D and it ended up in reality to be -1,25D. Glad I paid for the Ora system.
As of yesterday I am able to read J2. I can read the smallest cell phone font that I can set on my S10+ and it is very vivid. I can read the 1/2 unit scale on the insulin syringe that I use for my cat. My computer screen (39inch 4K) is very clear and vivid from 12 to 36 inches (30cm to 90cm). It has only been a week so its possible the near vision could still improve to J1? Before surgery I was hoping for J3.
This eye is the close eye for my mono vision so it is not set for distance.
I am very happy with the results. So far I am doing better than the right half of the following with a -1.25D:
Next week March 18th my left eye, the dominate, is getting the lens set to plano. And of course we are using the Ora system again.

For anyone reading this thread, I just found a very interesting Webinar on YouTube about the Eyhance IOL. Search on "heidlberg eyhance" and it should be the second result. Heidlberg is the name of the University that conducted one of the two European studies. There are screenshots from that study up-thread but this Webinar showed a number of metrics from the study that I haven't seen before.

As a premium monofocal option the RayOne EMV is better.

Interesting. I've never heard of it. The depth of focus is actually a little less than Eyhance but they're marketing it as a lens that works better in a Monovision configuration. I'm not really sure how it does that though or what actually makes is objectively better than Eyhance. They both work the same way (smooth increase of central power). The haptics look unique though. Personally I'd be more apt to place my trust in a big company like Alcon or J&J. But it's interesting. Worth looking into. Thanks.
