What are the risks and disadvantages of Eyhance? Looking into them as a possible lens choice in addition to Clareon
Monofocals.
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.
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.
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!
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.
That's right, now I remember that fact. Thanks for clarifying it.
Spring Google Dr Ben LaHood. He is an internationally renowned Australian ophthalmologist. I have an email from him saying that the Alcon Clareon is the best monofocal on the market.
Thanks. I will look him up.
My websearch discovered that Dr. LaHood is a paid consultant for Alcon (maker of Clareon) and Zeiss. Among other things, he's affiliated with something called the Alcon Experience Academy.
As for refracting eyes with Eyhance IOLs, JnJ receommends a well-established methodology that"s well-known to optometrists, ophthalmologists, etc.
You pays your money, you takes your choice.
Good to get that information!
Mary physicians are paid consultants to. optical companies. That does not mean that whatever they say is suspect. You have to look at their overall credentials. Most cataract surgeons stay with one manufacturer. Mine uses J and J. When I told Dr LaHood that, he recommended the Tecnis 1 and it has worked very well for me.
Thanks for clarifying that!
ha ha. u r now coping.
I.m not suggesting he;s a shill. But it does present a conflict of interest that, for example, would have to be disclosed in a journal article. Especially when a paid consultant is endorsing a product from the business that pays him (and even more so when he says it's the best such product), I'd like to see reasons that, at least in principle, can be checked against other, ideally independent sources.
I think that is a good idea. The more checking you do, the better but does take a lot of work!
If you Google "Europe Ophthalmology Times Dr Ben LaHood" it will take you to a number of journal articles he has written. Next to his name it says he is a consultant to Zeiss and Alcon.
I was able to get into the Alcon Experience Academy. It has many technical articles about refractive surgery, retinal repair. glaucoma, dry eye disease, etc., for eye care professionals. Johnson and Johnson has something similar with their jnjvision.pro
Dr LaHood and I exchanged several emails, and I surprised that he did that. He knew I was an American and would not be a patient of his in Australia, but he was kind enough to reply to me.
I also got some email replies from cataract surgeons at medical schools here in the U.S. Doctors don't like to give medical advice online, but I carefully worded my emails to assure them I was only seeking their personal experiences with IOLs. Some favored the Eyhance, some favored the Clareon. Others said they thought that essentially they both were fine IOLs. One said he preferred IOLs that had already been on the market for years, such as the Arysof or the Tecnis 1. Another reason I chose the Tecnis 1.
Eyhance is not a premium lens. It's essentially a monofocal that is slightly more aspheric towards the central part of the lens. I believe it is 88% identical to the standard Tenis monofocal. You will have no issues whatsoever with corrective glasses.
"premium" isn't really a factor there. a lens with altering power from the edges to the center is probably not optically the simplest thing to correct if you need to?
One question I have is how much more close up vision does eyhance give compared to Clareon in choosing the distance focal point? I have had different people recommend either Eyhance or Clareon since both have advantages.
How have you liked Eyhance and how long have you had it? What focal point did you target?
Eyhance is not treated as a Premium lens at my health plan and is free since it is a monofocal. My doctor has recommended it for distance for me as she has seen good results but then I would like a blue light filter since I have AMD. Can be hard to decide but don't like wearing glasses for close up so that is a factor also.
