Vivity Lens vs single focal lens
Posted , 12 users are following.
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.

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.

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

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.

Were both your Eyhance set for distance or was one eye corrected to give nearer vision

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.

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.

The peak of the Vivity defocus curve is lower than other lenses. I suspect if you shift it to the right by targeting intermediate, you'll end up with the contrast sensititivity / night driving issues at distance described in the warning. The surgeon I talked to about Vivity wanted to target plano for both eyes. Not sure how it might work in a combo like Ron is suggesting. Ultimately, I decided against Vivity because of the decreased contrast sensitivity and potential night driving issues that I wouldn't be able to restore with corrective lenses. But lots of people with Vivity report not noticing these problems. I do wonder how far away from plano they ended up and whether those who end up somewhat myopic have more of these issues.

I believe the shortcomings of the Vivity can be well compensated for by using a monofocal like the AcrySof IQ or Clareon in the dominant eye, while only using the Vivity in the non dominant eye. Whether you target the Vivity for plano or some myopia is a good discussion to have with the surgeon. If it is targeted for some myopia, then distance acuity in that eye will come down a bit, but it will be well compensated for by the distance eye with a monofocal.
