I have been read a lot about Vivity lens both at this web site and others. The reviews in general are 8 to 12 months old. I would like to know if getting this lens is worth getting. I am considering the traditional single focal lens, My doctor, of course, is talking up the Vivity lens. I am looking for good vision, I am active play tennis, and skiing. I would like to know what do people think of this lens after they had the operation for 3 or 4 months.
lm in the same situation as you, My doctor keeps talking up vivity saying its the best Lens ever but my concern is that vivity comes with this warning
'"Most patients implanted with the Vivity IOL are likely to experience significant loss of contrast sensitivity as compared to a monofocal IOL. Therefore, it is essential that prospective patients be fully informed of this risk before giving their consent for implantation of the Vivity IOL"
l just dont know how serious the low contrast issue is . l think l would rather go with a single focus monofocal lens for distance and have excellent distance vision and wear glasses for intermediate rather then go with vivity and be unhappy with low contrast vision and not need glasses. l want to find out more about how people find the contrast before l get vivity
Interesting I didn't know about the warning.
My doctor is saying it is so much better than the multi focal lens. I already decided not to get them because I read that they limit night vision.
I considered the Vivity but in combination with my surgeon decided against it. Alcon has a warning that contrast sensitivity will be reduced in particular at night. They say that if you get the lens in both eyes the effect will be less. That is true as there is always a slight binocular gain in vision compared to monocular. However, since the standard monofocal lens has a much higher contrast sensitivity I think the best way is to get a monofocal like the Clareon in the dominant eye, and a Vivity in the non-dominant eye. That way the monofocal makes up for the decrease in contrast sensitivity, while the Vivity EDOF gives you some closer vision. If the Vivity is under corrected closer vision can be even better with a small loss in distance vision for that eye only. Something to discuss with the surgeon.
Yes that is an idea l will talk to my surgeon about , vivity in one eye and monofocal the other. You often hear about people who go monofocal in both eyes set for distance and say they still have good intermediate and they say they are glad they didnt go with a premium lens My Other idea is to go with Eyhance in both eyes, both set for distance , that way l am sure to have the best distance vision , if l did that what sort of intermediate would l have , would l have arms lenght , car dashboad distance or be able to read the mobile phone if l stethched it out to arms lenght
yes by surgeon also said he didnt like multifocal panoptix and vivity is better, next time l see him l am going to discuss the issue of how vivity has lower contrast then a monofocal.
Eyhance in both eyes is likely to give you good intermediate vision, but not likely to give good reading vision closer up.
True. I'm a week out from surgery on both eyes. Computer and laptop text is crisp. My phone needs readers. Yes you can read it arms length and is clear. Well clear on my Note10+ which is about as big as you can get. However very small text is not comfortable to read. I now hang readers around my neck. Was checked today and I'm 20/20 with each eye but my dominant, right eye, is a bit crisper.
Daniel, I'm curious to know if you get a real near vision boost when outdoors in sunlight. I also have Eyhance in both eyes. It's very comfortable reading my phone for example when outdoors in sunlight. It does not have to be at arms length. Easy to see the time on my watch too at a normal elbow angle outdoors. Basically, it's no readers needed for me when outdoors in daylight. Seems that the combo of bright light outdoors plus the accompanying constricting pupil size makes a big difference for me and really enhances near vision. I can read the phone indoors at arms length also but only do that to check a notification or read a headline or other quick things. Phone reading indoors is more comfortable with readers for me.
There's daylight simulation photo in the Eyhance brochure that shows the far distance scenery and intermediate distance trailhead marker crisp & clear but the map on the near distance phone not clear. For me, the near distance phone would also be very clear when out in daylight. I'm hoping everyone with Eyhance gets that boost in near vision when out during the day.
Some great ideas. I have two questions: 1. Is there a difference in mono focal lens. Meaning brands or model differences. 2. Has anyone received two vivity lens and felt like they perform as expected?
Were both your Eyhance set for distance or was one eye corrected to give nearer vision
yes theres different types of monofocal, but l dont think theres that much difference between the different brands, l know Eyhance is a monofocal that gives more intermediate vision then the other monofocals thats why if l went with a monofocal thats the one l would choose
My Optomerist said two of his patients got vivity and both were happy with it and performed as expected. l guess most people will be happy with vivity and a minority not happy just like any lens
Yes I've seen that photo comparison your talking about. It seems fairly accurate but I have not checked my phone outdoors in daylight because my phone would need to be maxed out in brightness so I just don't bother to check it. That's interesting though so I'll need to remember to try it.
Interesting. On paper with the Jaeger test I read J1 outdoors in sunlight, and J3 indoors with normal home lighting. I have more trouble with my phone outdoors compared to indoors due to the higher contrast on the screen indoors.
There are some minor differences in the more common monofocal lenses that are used: . Tecnis 1 - First it is a clear lens. It has a -0.27 um asphericity correction. This theoretically reduces asphericity error to 0.00 in an average eye. . AcrySof IQ - It typically has a blue light filter, which Alcon claims mimics the natural lens of a 20 year old. Alcon also uses a lower asphericity correction of -0.20 um to leave some residual. They claim to have done some research on people that have supervision beyond 20/20 and they have this amount of residual asphericity. . Clareon - Also by Alcon and has similar features as the AcrySof IQ but is a newer material with about 10% more light transmission. I would get the Clareon over the AcrySof IQ and in fact did get it in my second eye. Was not available when my first eye was done. . I do not consider the Eyhance a monofocal. It has EDOF of about 0.35 D, which is technically not enough to be called an EDOF. So it still has some of the advantages and disadvantages of an EDOF lens.
I printed a Jaeger chart and J5 at 14" is of practical use indoors with good lighting. I can't read that as fast as normal reading but it is still useful reading. I can similarily see J3 indoors with good lighting with outstretched arms. Readers are needed for any extended period reading or in lower lighting for me.
Outdoors in daylight it's a solid J1 at 14". I'm getting that near vision boost from my non-dominant eye. There's some gain with the dominant eye too but it's not as much as the non-dominant eye.
I know that things can still change. I still have a couple of weeks of drops to do.
The target was first minus in my dominant eye and second minus in my non-dominant eye. I kinda wanted both eyes set for best distance but the surgeon said his Eyhance patients liked the results with the small offset and I trusted him on that.
Unfortunately my reading vision is being limited to some degree by my residual astigmatism. I see a shadow image to the right of the real image and that makes it harder to read smaller print and especially letters where the detail is lost by the second image. I am investigating a Lasik option to reduce the astigmatism, but I am not optimistic at this point that it will be a reasonable risk to take.
Thanks for that information. Will the Vivity len provide clear vision between the distance and intermediate range or is the clear vision only at two distance?
Clareon sounds good how long has that been available? I am not sure my doctor handles this len.
The Vivity lens is an EDOF lens and does not have a second or third focal point like a MF lens. It may not be quite as clear at distance as an aspheric monofocal but should give good quality vision down to about 20" or so. That is from theory and I while I considered it, I have no personal experience. I have an AcrySof IQ in one eye and the Clareon in the other eye. . The Clareon has been available for the last year or so in the monofocal version. Not sure about the Vivity or PanOptix. The monofocal Clareon is from Alcon like the AcrySof IQ, Vivity, and PanOptix. It is more of a new material than a new design.
