Intraocular lenses become dislodged due to scarring of the lens capsule, trauma, lens ligament atrophy, and laser treatment for secondary cataractsSecondary cataracts (opacity of the posterior capsule of the lens) sooner or later develop in almost all patients who have undergone lens removal Comment from : Oleg Voronkoff

Vivity UV, on eye blurry near and far Blinder eye feeling both eyes Instead of a nice halo have a horizontal lighthouse effect on bad eye Not happy Comment from : Don Geo

Thank you You helped me make my decision Comment from : R B

Doctors get paid more money to put in specialty lenses… Let me repeat that … doctors get paid more (are incentivized to recommend) specialty lenses Academic ophthalmology centers are less incentivized Think about that next time a ophthalmologist recommends anything but the standard lens Toric lenses are great too… vivity is a hell no!!! Comment from : Iced coffee 503

I know doctors that outright refuse to do vivity, that button causes too many patients to be unhappy These specialty lenses are not worth the trouble folks… and vivity is the worst! 80 percent happy 20 percent very unhappy Standard lens 95 happy… Comment from : Iced coffee 503

WOW ‼️ I NEVER Heard It Put Like This ‼️MERCY 😮 Comment from : Rhonda Townes

Thank you for the video, having cataracts and just had the 1st appt with surgeon and the decision feels very hard and subjective This gave me a bit more of data to help decide Comment from : Nando Nando

I will have cataract surgery on both eyes in 2 weeks because the condition of each eye are way different The eye surgeon recommended to use Vivity in one eye and the Light adjustable lens on the other eye so it can be adjusted as needed Just curious how often is this done using two different type of lenses? Comment from : Antonio Alfaro

Excellent explanation!! Comment from : Lori Himes

CataractCoach 1643 Would you recommend Vivity IOL for someone in their 40s who only has a cataract in one eye? Comment from : Casey Cook

Thank you so much for this information I am 50 years old and have cataract in one eye only My doctor wants to put in Vivity but I have my doubts since I feel I may not be a good candidate: I was highly myopic in my teens and as a youth and had lasik done on both eyes 20 years ago I have heard that since the measurements on a lasik treated eye cannot be precise, it is better to go with a monofocal lens In addition, since I may not be getting cataract surgery done in the other eye any time soon, I feel the Vivity lens could be a cause for imbalance with the other eye with the natural lens What type of lens would you suggest for my eye? I have Posterior Subcapsular Cataract in one eye only Comment from : Shiva Rahimi

Can i implant emv iol in the bag after pcr ,? Will that change the final result? Comment from : drabdulhaleem Altabshi

Sir I am an ophthalmologist from India , sir want to ask about your opinion regarding eyhance iol from jhonson&jhonson and Rayner Emv lenses Comment from : krunal bhavsar

Hello Dr Devgan, what is your view on micro monovision, targeting around -1 for the non-dominant eye with a monofocal lens? Comment from : Tim Handzel

Would such a outcome of myopia be variable across different cross section of populations Comment from : Dhami eye Hospital

Dear Uday Sir - Please make a video on new alcon monofocal Clareon Vs old monofocal Acrysof IQ from Alcon - Does the new monofocal clareon give better vision in terms on no contrast loss ? Vivity has contast loss - so is clareon better than Vivity - eagerly waiting - have to get cataract surgery done asap - Thank you so much for all the information you have shared through your videos on so many topics - I am so grateful to you Sir Comment from : pooja anand jugran

Hello SIr,brI got my right eye cataract surgery done with J&J Tecnis Eyhancehence Getting good contrast and intermediate vision ( laptop /even reading)brWhat is your take on putting the same IOL in the left eye? Comment from : Anil Kr

is it good for astigmatism eye ??? Comment from : マルカーノ

is it possible to have edof in one eye and mono focal in the other eye ? Comment from : vmx

10:18 What do the ostensible light ray lines in the EDOFfigure represent? The rays that pass through the -15 point just stop at that point and don't reach the retina Meanwhile, only the one horizontal ray reaches the retinal (labeled 0) So there appears to be neither a retinal image from the lens's -15 action, nor from the plano action Comment from : Graham Wideman

🤡mono Comment from : g w

Amazing clarity of thought and depth of informationbrThank you Comment from : Ilyas Ghauri

Nice informative video Comment from : Karan Khanna

at the 6:10 mark of this video, you show an image - but I don't understand what you're trying to show me At first I thought the image was comparing between two products Are you saying that the distance focus image (top image) should be more like the intermediate distance focus? Comment from : katycat2

Nice lectureTrue advice Comment from : TEJPAL PATEL

Just wanted to thank you for these videos Helping a friend make a decision about which lens Comment from : Son of Calypso

Just FYI your camera example is somewhat backwards You are correct that large aperture equals more light coming in, but a large (as in physical size, not the F-number) equals a small DOF, while a small aperture lets in less light but has a large DOFbrbrLater in the video you did say something about increasing the DOF by making the aperture smaller, so I believe the 1st- backwards -example may have just been in error Comment from : Marcus Riley

How about having a mix Mono for reading in one eye, and another lens that's good for far?brbrDo you recommend such ? Comment from : ian stuart

Great video How does the Eyehance compare to the standard monofocal now that it's been out awhileany limitations or discussion on patient outcomes would be great Comment from : JP

What do you think of the Vuity Eye Drops used to treat presbyopia? And can they be used for someone who went with the monofocal distance lens? Thank you Comment from : Generic

I wish I had seen this video prior to cataract surgery I had the Vivity lens implanted bilaterally not knowing the my left pupil was in the range of 25-26mm I had post cataract PRK in my left eye with no improvement and now I have to wear a contact in my left eye just to have some visual comfort due to the imbalance created I am contemplating having the lens replaced with a mono focal lens Your thoughts? Comment from : Raymond Berard

Just starting to use them Tx for advice Your opinion on Rayner EMV iol ? I have used them for more than two years already and get really goid results Comment from : Eben Laubscher

This video is really clarifyi ng, thanks Dr Devgan brI have not binocular vision, due to micro strabismus fron childhood in one eye I have a lazy eye, 75 vision I this case, would you recommend to me VIvity? In both eyes, or only one eye, or better monofocal in both eyes? I have consulted 2 doctors and they have different opinions on this Appart from this, my eyes are "normal", they could be suitable for Trifocal if I would not have the issues commented An answer from Devgan or other doctor with experience in cases sinilar to mine would be really appreciated, I am really stuck on this topic Thanks! Comment from : Ainhoa Martinez Calvo

Thank you for this very informative post I haven't heard of any doctor's office visit (among people I know) who were given this much detail about cataract replacement lenses Comment from : goosy goose

I really wish I had had access to this last year :) Comment from : F P

Sir is this vivity good for a patient who is laproscopic surgeon Comment from : Dr K V Ravi Kumar

You ended off arguing you would choose a monofocal, and that you don't mind wearing glasses when need be Isn't that oversimplified? But wouldn't you needat least two pairs of glasses should your iol be set for distance? So when driving and walking you'd need int/far bifocals, and when reading another pair of near glasses? Comment from : Pinch Code

So, if you don't hate wearing glasses you better go for mono optical lenses? Comment from : Hans Beukers

Excellent evaluation Thank you for this Very honest and true commentary Comment from : utube26able

What happens { theoretically } if you remove the cataract lens and didn't replace it with another lens? Comment from : Edward Ames Castellano

After implanting more than 50,000 IOLs , totally agree , monofocal is the best IOL Comment from : Usama Al-Hassani

Agree…You said it all, and as an ophthalmologist I would never trade image quality for spectacle independence, and like the graet majoritry of our felliws, I would choose a monofocal IOL in my eyesAnd now that some, not all but many, of Eyhance with 20/20 and J1 this is a complete nonsense to put a multifocal, unless the patient requires spectacle independence and knows the side effects this trade will causeWe all know that cataract patients with loss of contrast are happy with multifocal, but that one with good vision and early cataracts, they are the ones that will cause problem and complain or that RLE(wich I do not do) Comment from : Murilo Borges

Dr Devgan, I'm wondering if you would put a monodical (for distance) in the 2nd eye I had the Vivity lens implanted last week The other eye is coming up soon and I'm thinking I would like to save the $2500 and go with the monofocal lens Does the brain usually adjust to that slight difference? (I'm aware I'll be giving up my close-up vision and will need readers) And I know you probably don't want to give advice to someone who isn't your patient and who's eyes you've never examined, but - in general - do you think there is a possibility this could work out just fine? (And I will indeed speak with my doc about it) TIA Comment from : BeshaPike

Thanks for the honest and balanced review of the Vivity IOL and for talking about some of the other EDoF IOLs on the marketbrbrOne IOL you didn't elaborate on with the ray diagrams was the oculentis comfortbrI was wondering if you had any experience implanting this IOL and what your thoughts are on its performance? Comment from : MrWatshisface

GREAT VIDEO! Thank you so much for explaining these details ❤️ 😉 Comment from : Suzie Hartwright

Dr Devgan, does the Panoptix lenses provide more contrast sensitivity than Vivity? Less? Or about the same? Thank you Comment from : Sue Anna Joe

Great infomation So, wich target do you recommend for the first eye? Comment from : Daniel Guarache O

That was fantastic explanation: you helped me make up my mind as to which lens to go with Comment from : Carole Matar

Awesome video, thank you! Comment from : André Marques

Dr Devgan at 1:05 you got it opposite Shallow depth of field is due to larger aperture (smaller f-stop number) while wide depth of field corresponds to a smaller aperture (higher f-stop) Secondly, shutter speed has no effect on DoF It only affects exposure 🙂 Comment from : Farooq Khan

Great teachings! I agree with you in everything, but this video reinforced some impressions that I was already having with Vivity Good IOL, but not for all Comment from : Alex Abdo Martins

Great review of the Alcon IOL Thanks for the refresher! Comment from : Tim Root

Thanks for your recommendations Sir Comment from : Haidar Almamoory

You get one chance to be perfect: when you are born God is the Master Physicist and Engineer The rest of us fall short-every time Comment from : Keith Thompson

Thank you for sharing it As you mentioned monofocal IOL for best image quality, how about eyhance IOL compared with monofcal IOL in terms of image quality ? Comment from : Vikas Sharma

Thanks a lot sir Comment from : ALI AL-NASRAWI

Very interesting as usual Dr Devgan thank you 👍, what do you think about this choice for emmetropic patient : monofocal lens in the dominant eye and an EDOF in the non dominant eye? Comment from : anis kaci
