I;ve had two consultations with my doctor and all she does is let me ask questions. Never explained much at all. This is the clearest explanation I've seen thus far. Wish you were my doctor.
Clear and simple, though not simplistic, presentation. Thank you. And yes, the best presentation I've seen on CZcams.
I believe Medicare should pay at least the portion of the expense of basic lens for those chosing the lifestyle lens. Medicare and thr insurance companies denial of paying any portion of lifestyle lenses is just a way of increasing their greedy profits at our expense.
very clear and precise explanation doctor I will have my right eye cataract surgery in the next 2 week.
This is exactly my choice because l have astigmatism therefore l need toric.thanks to my Dr .already chose it for me hopefully this will correct my vision as lam due for surgery next week
best video explanation I have seen... thanks
Very good right inf you r providing particularly while you r choosing the right lense Thankyou so much
Very very good explanation I need cataract surgery wish I lived closer
thank you very much for the
significant information. god
bless you.
I will have to have cataract surgery sometime in the near future.I have 2020 vision with my glasses , but iam bothered with glare alot. Thank you for telling me about that intermediate vision.I was a always troubled about not being able to read most items on the shelf in the supermarkets.I never knew why i had the trouble and i never discussed it with my optometrist. Iam happy that can be resolved, but iam extremely anxious over the whole ordeal . Sorry, i do not live in LA.Iam located in New Hampshire .Thanks again!
thank you dr
Great Video
I may recommend my cataract patients watch this thorough video.
Just Super!
This is the best description I have heard yet. I just got the monofocal lens in both eyes. I wasn't prepared for the lack of clear vision in the intermediate and near ranges and really hate having to carry multiple glasses with me and changing them continually. So I'm going to see if I can get glasses I can wear all the time that have progressive lenses!! I hope so.
May i ask do you use more than one pair for everyday use? if drive a car do you need glasses to see the speedo and dash gauges.
I get Alcon IQ vivity about e year Great almost perfect best in the world
Your surgeon should have explained that the monofocal lens would only give you good far vision.
@@garya2223 …or good near vision
@@mollypitcher9380 True. My suspicion is that the doctors do explain it but people aren't listening or only hear what they want to hear.
Have you placed the RxSight iol in a patient yet? If so, what do you think of it? I like the idea that adjustments can be made after surgery. I am also aware that with a standard toric lens, it can rotate as the eye heals after surgery reducing its effectiveness. How common or rare is this? It seems like the RxSight addresses that. I was considering a Eyhance toric lens. Finally, if I were to try a minimono I could see if I like it and if not, change it back. Could not do that with any other lens besides RxSight.
Thank you
Can I choose 2 mono and 1 for near ;1 for distance ..will my eye not be confused with that?thanks
Nice presentation. What is you opinion of the Tecnis Eyhance IOL? Would this slightly advanced monofocal IOL be appropriate for a myopic patient with the end goal of -2.00 to -2.50 diopter rx? Thank you.
We've had wonderful results with the Eyhance lens. Many myopic patients enjoy this lens, as it provides a slightly extended range of vision, without the drawbacks of glares, halos, or decreased contrast sensitivity. Keep in mind, that with an end goal of -2.00 to -2.50 diopter Rx, you'll be aiming for crisp near vision and will need glasses for distance vision (e.g. driving, watching TV across the room, playing sports such as tennis or golf). As always, make sure to have a full discussion with your ophthalmologist!
So when are they going to approve juvene and fluid vision accommodating lenses?
Thanks for this video Michael. I also saw the question from Joel and am somewhat worried about the effect of the Eyhance Toric IOL with regards to frequent activities quickly reading a short text on my smartwatch and reading papers in the office whilst also working on a computer. Would it be possible for you to also respond to this? I don't mind using glasses sometimes, but I would prefer not to be forced to put them on and off continually..
The Eyhance provides a little bit of extra range of vision. If your Eyhance lenses are set for distance vision, you'll likely need reading glasses for tasks such as looking at your cell phone, looking at your smart watch, reading, or looking at smaller text on a computer. If your goal is to avoid glasses for these near tasks, a multifocal/trifocal lens such as Panoptix or Synergy might be a better option, just bear in mind the tradeoffs of these lenses such as rings or halos around lights and decreased contrast. As always, consult with your ophthalmologist!
Cool !!
Love that southern California accent?? Yep there isn't any that makes it unique..ty for Info
Is the vivity lens a good option ? After comparison to panoptix it seems that vivity is the better choice !
Vivity is awesome particularly if you add a diopter to the non dominant eye. This is blended vision and for me I don't need glasses at all for any distance
am a teacher of 58 years old.I have operated my right eye cataract with Acre-soft IQ Toric(2.5 cylinder) Monofocal of 6D. can I implant Alcon Vivity EDOF Toric( 2.5 cylinder) IOL of 8D for my left eye and how it will be suitable for me?.Please guide me as early as possible. I will be very thankful to you.
Doc i have a cataract surgery in march2 2022 but i suffered for astigmatism headache and discomfort plz advize Doc
i enjoy watching your videos very much, you explain things very well. i would consider doing the cataract surgery, but because of many allergies i am afraid that my body will not accept the new artificial lens. can you please give your opinion doctor.
What do u recommend for post RK 30 years ago?
If I have only one eye done monofocal distance can my brain focus both eyes
My left eye 4x worse than my right.
I can see pretty good now with my right eye I can see distance intermediate and close
So not getting it done.
I have seen so many videos where people unhappy with mono distance
I have surgery but paying extra for laser
And then my rk corena is an issue ??
I have a similar issue and would love to hear options
How common are dysphotopsias following cataract surgery with the implantation of a monofocal lens? My wife had cataract surgery three years ago and the problem still persists.
Only 2 percent following a year of cataract surgery.
I would mention it to an optometrist, if the vision is bothersome enough to affect her daily living.
I've worn glasses all my life - prescription around -6 diptre. About 6 years ago I developed cataracts, which have increased my spectacles prescription to about -8. Presumably the cataracts will get worse and I'll need IOL's. I need sharp vision for work. I do at lot of CAD/CAE, so multifocal OIL's are not for me. It would suit me best to be set up for -6 dioptre without glasses and just wear glasses for driving.
Michael, is the availability of monofocal IOLs limited such that asking the eye surgeon for -6 will cause him a problem? Is there any medical problem inserting a -6 lens?
You might be better off to have the Dr. correct you so you are only -2.25 diopters nearsighted. That way, you can read with no prescription and only need glasses for television, and driving...
@@1953childstar : Really? I read books without glasses before the cataracts developed. I haven't got time for TV. Don't watch it - only CZcams snippets. Using a computer needed only around -4, but I could get by with -6, providing astig and chroma are good.
Us high minus people who do a lot of CAD/CAE computer work know that astigmatism correction is important, and low chromatic aberration is critical. Long sighted people don't have this chroma problem, but high minus folk like me learn to specify that low index glass be used in spectacles. Spectacle shops have no trouble meeting that need, but eye surgeons don't seem to understand. Chroma is not a problem in normal life, as the brain gets used to it and corrects it. But it can't cope with computer displays.
Correcting astig with IOL's is apparently no problem, but presumably IOL's have chromatic aberration. I have had no luck at all finding out to what degree and if it will matter. Local eye surgeons don't want to discuss technical issues, they just want to stick multifocals in and go to the next patient. Seeing an eye surgeon is very much an assembly line process.
@@keithammleter3824 I absolutely agree with you.They won't answer our technical questions,afraid that they will lose a patient and his money if their answer is not what you need.It's frustrating.Where is the honest doctor?
@@terrapinalive6192 : Lack of honesty certainly plays a part. I think a lot of the problem is that surgeons in general tend to be like Unimat robots in a car factory. They learn how to do surgical procedures to a high degree of competence, e.g., how to insert IOL's or take out an appendix, but remain ignorant of what the pros and cons are. But the more procedures they do, the more money they make - there is no incentive for surgeons to learn about all the ancillary issues.
does a multi lens correct for astigmatism? or are toric lens always mono?
There are toric options for multifocal lenses.
Generally, when we say "toric lens," we are referring to monofocal toric lenses.
But you can also have "multifocal toric" or "symfony toric" or "Panoptix toric" etc. for the multifocal lenses with astigmatism correction.
Is it possible to remove a previously-implanted mono lens and replace it with a toric lens?
Yes, this is possible, although if you have received laser YAG capsulotomy of the lens already, the surgery would have higher risk. Doing an intraocular lens exchange can be done by an experienced ophthalmologist, but like with any surgery, there are risks. Make sure to have a full discussion with your eye surgeon regarding the risks and benefits of a lens exchange!

PS chk with your Ins co. see what they will/wont pay for. The multis are very expnsv and my co wdnt pay. Got near vsn lnses (1 - 2 ft for computer) and Dial Vision glass til I can get pscrptn. They work FINE for 3ft out to looking at the moon. They do have limits tho - some periphrl reflections and smaller visual area (dstortd periphrl.) I dont drive but they wldnt be good!!
Supraphob regen multifocal lens cost
Waiting for a flexible lens that hooks up with the focusing muscles..
Why not the Dr recommend the kind of lens that suits your eye???
Why can I see lens in some people eyes?
thank you doctor chua ............ now i'm definitely not getting cataract surgery.
Going blind is always an option I suppose
