Notes on Tecnis Synergy has received FDA Approval.

Man you are tied in the grapevine. I just saw it at the FDA PMA site. I am reading through the 53 page Summary of safety and effectiveness now. Any word on when it will be commercially available.
I hate to be the first one in the US to get this lens, but I really can not keep procrastinating and waiting for more Real-World results to be published.
Hmm, I think I will be 2nd right after I hear back how it worked out for you, LAL.
I also saw some approval for Tecnis Symfony IOL, is that the Plus or something else.

the symfony one is the blue light filter symfony with yellow tint called optiblue. the synergy is default yellow tint.
i think synergy should be available in June.

I really have not taken the time to research IOL tints and their associated effect such as circadian rhythms..
From what I read Synergy is a Violet Light (very short wavelength) filter and keeps most of the blue light. This is suppose to help with LED lights and reduce halos from LED headlights.
I am now wondering if having different IOL tints each eye makes any noticable difference. I just looked into Kelvin Temperatures and lightening, when remodeling my house. I wonder if one IOL would be like Daylight and the other one be like Warm Color. I guess I need to do some research into this topic.

Yes it is same consideration for me as i have the non tint symfony. there are people with symfony/panoptix and symfony/synergy combinations.

Keep in mind that the natural lens in the eye has blue light filtering. The clear IOL lenses on the market allow much more UV and blue light into the eye than the natural lens does. Alcon's blue light filtering simulates the natural lens for filtering. Having a clear lens is actually unnatural to the eye, which cause some to speculate that they may cause long term eye damage. However I believe that is just speculation and I have seen no documented evidence of macular damage due to using a clear IOL. The experience here may be somewhat constrained by the fact that most get an IOL quite late in life, so the time for macular damage to occur is limited.
.
I suspect that the Tecnis violet light filtering is somewhere between a clear lens and the Alcon blue light filter. It may be a way to provide the same benefits as the blue light filter but allows them to distinguish themselves from Alcon for marketing purposes. The main benefits would be in reducing chromatic aberration effects.

My concern is what effect, if any, there is when mixing IOL tints. I need to double check but I think my current IOL is UV blocking but no blue or violet light blocking.

At one point I found a study where they implanted a blue light filtering lens in one eye and a clear lens in the other. I can't seem to find it again using Google. I believe the reason for the study was unrelated to the filtering, but they came to conclusions about the mismatch as well. From my recollection there was basically no issues reported by the subjects in the study, in having a mismatched colour filter.
.
I currently have a blue light AcrySof in one eye and a cataract in the other eye. They are very mismatched for colour currently. While the AcrySof has blue light filtering (yellow lens), the colours seem very bright and even blueish. The cataract eye in comparison is now quite noticeably yellow. But, unless I close one eye or the other I don't even notice the colour difference. I would say that the brain just blends them.
.
My thoughts are that a mismatch would be a non issue.

A couple of other thoughts. I think getting this lens well centered/ placed is so critical, make sure you go to an Opthamologoist with lots of experience with premium IOL including Trifocal, EDOF and MF IOLs. I think you mentioned Vance Thompson Vision that is well known.
The other think I am thinking about is refractive targeting. For my current IOL I had them target Plano. I would normally recommend Plano or slight Myopia (assuming no monovision goals), but with this IOLs amazing close vision, I am wondering if slight hyperopia would be the best option.
Now that this lens is FDA approved I am writing an email to some of the Opthamologist who were involved in the US clinical trials, which were done at 12 sites. Sadly the doctor in Florida who was involved in the Syergy trial passed away.
Hopefully one of the doctors will reply to my email. I wanted to get your thougths or others before I sent out my email. I am not including the intro of my letter, just questions part. I guess I need to provide some background information so my question are clear. So below is that BG information and what I am asking their opinion on:
From what I read, this IOL combines EDOF with MF and the only other IOL I am aware of that obtains near vision down to 33 cm is the Tecnis MF 4.0, which came with large Halos.
I am OK with the Halos I see from my current +2.75 add MF, but I want to avoid an IOL whereby the Halos would be worse and it is unclear to me how Synergy is achieving that amazing close vision down to 33cm.
1)What has your patients experience been with the Tecnis Synergy vs the Tecnis low add +2.75MF in regards to dysphotopsias, especially halo size from light sources when driving at night,
2)Due to the amazing close VA, can you provide any thought on refractive targeting? For my current MF I targeted Plano, but with this IOL’s close vision performance, do you have any thoughts on whether slight hyperopia should be targeted instead.
3)From what I read Synergy comes with a violet filter. Any thoughts regarding issues of mixing IOL with different tints?

this is a great post rwbil. i feel hyperopia should be targetted with trifocal as the near power is fixed and does not change just because you made distance better.
in terms of lens centration. i think the lens auto centers based in the capsule size. they should have ability to center the iol on constricted pupil as my pupil constructs unevenly. if the lens was moved in the nasal upward direction my edge problems will great reduce.
also dr gabric said that synergy eye image is smaller than the symfony eye. is that standard experience?
have u had YAG on multifocal?

I have not need YAG, cross my fingers I never do.
Yes, Dr. Gabric is a big supporter of Synergy and who better to get info from than an Opthmalogist that has Symfony in one eye and Synergy in the other.
He was talking about some picture he was looking at and contrast sensitivity; saying Symfony was better and provided a 10% larger picture. I am not sure how to interpret that information. First I have the Tecnis MF so not sure how it would compare in picture size.
Hopefully if there is Synergy CS loss, my other IOL will compensate. In a perfect world my hope is the Synergy helps me pick up a little more close vision and of course intermediate, so I can hit that tennis ball better off my racket and as long as the halos are no worse than my current MF, I will be Happy. I am not sure this will happen, but it would be so nice to pick up a magazine or book and be able to just read it comfortable without finding the sweet spot or having to find a good light and reading glasses. I cannot keep a pair of reading glasses when I need them on hand if my life dependent on it.

just guessing but thinking 10% bigger picture may refer to peripheral vision?
