Drawings of my positive dysphotopsia with Tecnis ZKB00
Posted , 16 users are following.
Hi there,
Just figured I'd share what I was (am) seeing with my Tecnis ZKB00 +2,75 lens in my non-dominant eye, with a worsening cataract in my dominant eye that has it measured at -2.5 correction needed (and pretty dramatic light effects with the cataract too...but these drawings are what I saw with just the "fixed" eye looking).
I was quite frustrated for weeks and so I drew what I was seeing (couldn't take a picture or a screenshot of it!).
So I've attached the images I drew over the first few weeks, in case it helps anyone compare to what they are seeing.
My visual acuity is fantastic with that eye, but the light effects include when I look at the stars and moon. 😦
FYI, since people may be curious... I am considering options for the second eye, will likely get monovision for distance (or maybe just a touch undercorrected if I think I'll keep this multifocal in). If that settles these light effects down, I may stay put with that combination because I might be able to get by daily tasks like grocery shopping and phone checking without reading glasses...and just need one-sided readers for long periods of near work. If I still get halos when I look at the moon and stars, then this multifocal will have to go and I'll go for monovision of some sort.
Hope this is helpful. It would be fun/interesting if others wanted to doodle what they are seeing and post them in the comments...1000 words...

I should probably put some words in here that will help future searches, so here goes...
halos
glare
night vision
starburts
ghost images
side effects

Thank you for posting those images. They will be very helpful to others in the future. I'm interested to see if this lessens for you over time. Hopefully it will.
I see halos around headlights and some other similar light sources that are similar in size to what you are seeing. However, I don;t see them around starts/moon or many of your other circumstances and they aren't intense enough to impact my ability to see other objects.

Thanks for sharing.
In a few days I will know, if the Zeiss Lara does the same, but I am not worried though, maybe a bit naive, but at least not worried 😃
Or maybe I am not worrying because I really can not see that well on white paper with my cataracts, so I am having a really hard time seeing your drawings anyway 😃
In Denmark it has been quite some years since the bifocals were used, here it is either trifocal or edof, or monofocals off course.
The Lisa trifocal came 7-8 years ago, and I think no one have used the bifocals since that.
In fact many get the trifocals here without having cataracts, just because they have presbyopia and wants to get rid of the glasses - i guess they would think twice, if they saw you drawings....

I hope you have NONE of these! I don't think you're naive...you're one of the most thorough people here. Other patients have zero or miniscule halos. It's totally possible to have better optics than I or Sue.An2 do.
My ophtho chose the lens, offered me the Symfony for "less glare" (he didn't really highlight halos) but said more folks needed reading glasses with it.
Perhaps if I had looked myself at the specs I would have chosen Symfony. I have never needed +2.75, only +1. My near vision may be more than I actually need...it's about 30 cm now. (Reading phone with elbows bent to 80°)But I was insistent that I didn't want reading glasses....now that I'm living this, I realize that glasses for longer sessions would acceptable...it's the need to have them for every single glance at the phone or labels that is hindering.
I also told him that I prefer conservative tried and tested solutions. So I conveyed suspicion of new technologies ..perhaps I conveyed that five years isn't very long for a new thing. Again, if I'd researched perhaps I would have concluded differently but I have to accept that life works out...no sense in blaming myself.
Whats so hard about this is one has to make a permanent decision without knowing how it's going to work out. I can change this once, but not twice.
I'm also realizing that the clear far vision energizes me and so despite the fact that perhaps most of my daily life is spent at intermediate and near (as most urban people are), I still prefer to have clear far vision. Maybe I'll feel differently if I get a far lens that really messes up my intermediate.

I agree, I feel the same way, I would not like to need reading glasses for shopping, socializing or writing a text message on my phone, but reading glasses for some tasks at home, at the office and in the garage for the small stuff I can live with.
My surgeon thinks that the At Lara (like Symfoni) will do this for me, but we will see.
The Lara is relatively new on the marked, and I have had the same thoughts like you, about not wanting to be the test person.
But I realize, that after just one year, many thousands already have these lenses worldwide, if the lens was bad I am sure I would have found stories on the internet.
I have heard several stories about the side effects you are having, where people say they went away after 6-12 month, and even between 12-24 month some still get significant improvement, but the first 6 month they never believed the side effects would ever go away.
I hope for you it gets better, it is really a difficult choice you are facing right now.

thank you for sharing this with us. i wish i would have thought of this when i complained of ghosting images before my exchange of restor 2.5 len...it was tilted when implanted during surgery. i kept telling the dr what i was seeing and he didnt want to believe me, saying the surgery was a success, etc. i finally went to another dr who saw the tilted lens and also saw that the wring lens type was used for my specific needs. when the exchange was complete, the ghosting disappeared!
but like the tecnis, the restor 3.0 has 12 concentric rings, and i see them all the time if i pay attention. around any light source, or water droplet. I find it fascinating, and i also check to make sure i can see each seperation in those rings. I'm assuming when its time for YAG those 12 concentric rings will blur together.
i also need a large amount of light in the blue spectrum to see very clearly...20/20. dr says stay in the 4k-5k blue light spectrum. cloudy days and low light definitely make things more challenging. ive changed light bulbs throughout the house to accommodate this need. some florescent lights still give me a problem, especially if the ballast is flickering.

The rings are on the IOL so I am not sure YAG will fix that?

Hi Julielyn my concentric ate part of the Symfony design so assuming I will still see the distinct rings even after YAG which may not be in too distant future for LE as I suspect I have PCO bow in that eye.

i meant the blur...i realize the 12 rings are part of the design, hence why we are able to see clearly at different distances

Do they look like that for you Tamarind?

Interesting digital images. My concentric halos do have some radiant lines but they are not nearly as crisp or thick as those on the upper image.
I don't really have what the lower image shows...my starbursts have spikes that are closer together and finer. That's not the effect that bothers me, probably because it's bright enough that I just look away. They're actually kind of pretty.
The halos might be pretty to some but they pull my eye away from the crystal clear dark objects so all I tend to see is those friggin' halos. I have to deliberately make myself ignore them and concentrate on looking at the clear dark surroundings. Then I'm always impressed at my visual acuity. But it's a lot of work and "positive thinking".
The ghosting is annoying because most times I can't tell that it's not real. So I am concerned that with two of these, I'd lose all basis in reality for intermediate or distant objects. Up close, the ghosting and halos disappear optically. Through binoculars, for example, the world looks astounding.

i think people call those fine speckles radiating with the halos spidering. And yes, I have that too.
Interestingly, I am seeing that with my left (still cataract) eye and had never noticed that before. Sometimes I think the brain is interpreting the light scatter from the cataract differently now that it has an alternative light scatter in the right eye.
My cataract is an oildrop cataract, so more central. This creates a lot of (somewhat correctable) nearsightedness and lights turn into blurry Mercedes Benz symbols.

I see starbursts just like the one shown in the first picture, day and night time.
Night time is the worst time, a very dangerous situation that I cannot wait to see if "maybe" it goes away The size of the starbursts from end to end are 20+ times the size of the object they surround. My first surgery was in March of 2019: I had one of those Symfony EDOFs removed yesterday and replaced with a monofocal lense. I will have the other EDOF removed in the very near future.Wish I would have gone with the tried and true monofocal lenses.

Hi ann, Thank you for sharing your experience. I wish that both of us were in the percentage of patients who don't have these light effects!
Would love to hear how it is with a monofocal lens, and which one you got implanted...if you are so inclined to share.
With gratitude,
tamarinda

Unfortunately, your post didn't come up when I first searched for something on the Tecnis ZKB00, so I started a new discussion:
"Ghost Images with Tecnis ZKB00 (+2.75add) Multifocal Lens"
I am not totally sure if you are seeing actual ghost images as I am, but will be most interested in what you have to say on this after reading my post.
My left eye suffers from astigmatism and has the Tecnic ZXT225 Toric lens fitted. I don't have any ghosting issue with that lens, only a reduced close focusing range, compared with the ZKB00 (not good enough for reading a book).
PS: I have now seen your other post: "Tecnis ZKB00 multifocal combined with a monofocal?"
