Notes on What Are the Risks and Disadvantages of Eyhance?

I've tried to get an answer for this for weeks. But what I've been able to gather from discussions here is that probably one of the issues is related to getting accurate refractive readings for glasses because of the altering power of the lens and the more powerful mid section at the axis.
Since you're going to need glasses with these lenses since they are essentially mono-focal lenses with no guarantee of intermediate vision, hampering the ability to get the best possible glasses possibly may actually be an issue.
I'm scheduled for these lenses in the beginning of march and I have to make a decision soon to alter my plans. The fact that I have so much doubt maybe a sign I should change plans. The premium lens market is full of shiny things and all lenses are compromises, The more I read the more it seems like a pursuit of money and marketing. Putting something funky in the eyes feels less and less appealing the more I read about it, unless the benefit can be clearly proven.

That is interesting feedback about the glasses. There is so much info. out there and it can be difficult to make a good decision specially with little prior knowledge or experience. Good luck!

It's really a terrible decision, no good answer. I also decided on Eyhance, surgery in 5 days, my feet are as cold as ice...surgeon said he would put .5diopter for better near vision in second eye, after weeks of exhaustive questioning. I figure, if the first lens feels bad, there are 3 weeks between surgery and I could stop there. or if it seems like enough, I could stop there. It's aggravating there are no clear answers. I never wore glasses, 58yF - just readers in the past few years- I thought I just needed glasses and was thrown into this IOL soup! So much pressure with cost incentives added to the pot. I'm still wavering about going to India to have it done. Imo, in other countries, doctors are much more forthcoming. But my eyes are bad and I need to do something. Indian doctors almost across the board don't recommend Panoptix. Vivity is their lens of choice but my surgeon doesn't offer it, I kind of think Eyhance could be just as good as Vivity with the .5 near vision correction. ( I understand it's not the same, but there are tradeoffs) Basically, the amount of light entering the light doesn't change, it's how the lens spreads or moves it around. So, I want clear vision, crispness of colors, good contrast, but don't want to have worsened intermediate vision after going through surgery. But I do want to get back to seeing, in general. The cloud and the extreme light sensitivity are really wearing on me. The array of lenses doesn't help. Bottom line is they are taking my cloudy lens and putting a piece of acrylic in my eye. The optometrist said I still have some accommodation, which is why I don't always use readers, without any detail. Their answers have been as foggy as my lenses.

One good strategy is to target distance vision (-0.25 D) in the dominant eye and then wait the full 6 weeks to see what you get before deciding on the second eye. If you get all the distance vision you expect with the first eye, then you can go for more near vision with the second eye.

Thanks for the tip. That makes sense and might be what I will do.

In that article that Ron referenced and that I replied to, the author said that for patients with AMD, he would target distance. He preferred mini-monovision for someone with no eye disease.

Interesting comment. My doctor originally suggested intermediate because of the gallean telescopic effect which was confusing??? When I asked her to clarify she now says distance would be fine. I am speaking with her on Tuesday to find out why she originally suggested intermediate and to explain more. I am now, however, deciding to get distance because of driving so I am happy to read the comment about AMD patients and choosing distance. Thanks for posting that!

I think that with AMD your future vision is a risk. I think if I was in that situation I would hedge my bets and go for one eye closer and one eye further. But, at the end of the day your vision can be corrected for refraction regardless of which way you choose. I would base it on what you want to see without glasses, if that is your priority.

I am going to try to get one eye closer and one further but not by a great amount since I could not test mini-monovsion with contacts. Someone on "Eyhance Review" got both eyes the same at -1D and some thought that an unusual choice? I thought that might be possible using Clareon to get better intermediate vision?

I think you would get similar results with Clareon as to what you would get with Eyhance. The range of vision is going to be mainly determined by the split in the target range you choose.
.
I think from what you describe for vision and what your eyeglass prescriptions are, and combining that with your preference to not use glasses despite needing them for the best vision suggests you must be pretty tolerant to vision that is less than perfect.
.
I know you made a pretty valiant effort to try contacts to simulate monovision, but despite not having tried it, you have kind of done the same thing by not using eyeglasses for fully corrected vision.
.
My thoughts are that you would likely be pretty tolerant to mini or micro monovision approach. And the backup plan is always glasses.

Micro-monovision is something I would like to try after I get my doctor's input on Tuesday. I had the same thought the other day that maybe I am already experiencing monovision with my eyes without glasses.

Ron, I want to thank you for all of your help. I am going into the surgery tomorrow and feel I have greatly benefited from your comments, insights and tips!
I have chosen the Clareon Monofocal with the blue-light filter for the left eye at -0.39D.
I will be scheduled for the second surgery 7 weeks after this one and have informed my doctor that I will be getting my eyes checked at about 5-6 weeks so that she can get input from the left eye to assist with choices for the second eye. I am going to try some form of mini-monovision to get some better closer vision for the right eye.
I am going to post some feedback after both surgeries after a few weeks or sooner.
Again, thanks for all of your valuable comments. I needed that help and it is much appreciated!

You are quite welcome, and I wish you well with your surgery. These things tend to go much smoother and easier than we anticipate ahead of time. I think you have made good choices and you are wise to defer the decision on the second eye until you see the outcome from the first.

All the best,
Ron

In that recent article on IOLs for people with AMD that was posted here, basically said MultiFocal (MF) lenses were not a good idea, and should be avoided. It was less clear on Extended Depth of Focus lenses like the Vivity and Eyhance. Seems to me that the advice was worded something like probably good to avoid, but that is not in general agreement with all the experts. My thoughts would be that the more the depth of focus is extended the higher the risk. Vivity extends depth of focus by about 0.5 D, and the Eyhance by 0.30 D. These are not large amounts, but the Eyhance is less of a stretch, so probably has a little less risk, along with less of an extension.
.
My thoughts would be to stick to pure monofocal lenses like the Tecnis 1, AcrySof IQ, Clareon, or enVista. With AMD there may be an advantage in a lens with blue light filtering.

Yes, I would prefer the blue light filtering. BTW, she said Vivity is out because of the AMD. I am going to convey this to my doctor to see what she says. She was receptive to Eyhance but we are still in discussion about it.

I don't believe the Tecnis 1 or Eyhance are available in blue filtering. The AcrySof IQ and Clareon are, but of the two the Clareon would be preferred as it is the newest material and perhaps a little more resistant to PCO.
