I am going to have a cataract surgery for my left eye. As I have -1.75 D of Astigmatism, Alcon Acrysof toric lens seems to be the first choice in my mind. My surgeon initially advised me to have a LRI instead of the toric lens. As I have a moderate dry eye and I don't want to risk for a LRI at this moment.
Another concern is the blue filter feature in the IOL which may cause the image looks yellow tinted.
No the question is HOW MUCH (e.g 30% ??) blue light is blocked ? Or how yellow does it look ?
I cannot find the answer as most of the articles I got from internet just said it is blue light filtered
When I look at the picture of the IOL of brochure of Alcon, it looks completely yellow. I am not sure this is just icon or the real IOL looks that yellow.
I have some light sensitivity and always find the light too bright (not sure this is because of the cataract). I wear lightly brown tinted glass even indoor. I think a slightly tinted IOL may not cause much problem but may even make me feel more comfortable.
Can someone implanted this lens share with me 'HOW YELLOW' does the IOL look ? When you implanted the IOL on one of the eyes before the other one is implanted, do you see a significant difference in color perception.
Thanks Dr Hagan.
Yes, 'how yellow my vision will look' is more related to me. But all the picture shows the alcon IOL looks like a lemon. I guess it is not the color of the real IOL
I think I can tolerate or even get benefit from slightly tinted as I tinted my glasses anyway. In order to ensure I will not have problem in the future, I just want to imagine how does it look to me. If there are some simulated images of how people look with this IOL will be great; otherwise if I know how many percent of blue light begin blocked (I guess not 100%), I can use some Photo-edit software to simulate it myself. Even some subjective description like mild yellow, pade brown or whatever will be helpful for me to make the decision.
There are not many TORIC lens in the market and I don't plan to do any LRI to worsen my dry eye. If I don't choose the Acrysof, I can only leave this almost 2.0D of astigmatism uncorrected.
My reStor implants (I'm one of the happy customers) came with a slight yellow tint. When I read about that, it worried me since I'm a craftsperson and depend on accurate color vision. My surgeon told me, however, that the amount of yellow in the lens was designed simulate the values of the eyes of a 35-year-old. Having passed that mark some (cough, cough, mumble) years ago, I decided that it could only be an improvement on what I had recently been seeing through my cataracts!
In fact, although the folded lens looked yellowish when it was inserted, the yellow disappeared as it unfolded in my eye, and several days later, colors looked bright and normal to me--no discernable yellow tint at all.
Did you implant one eye or two eyes ?
Can you describe a little bit about how the yellowish (in the first few days) ? Does it looks like some tinted sunglasses with brown/amber colour ? Or it really looks yellow ?
I just email Alcon and they sent me back some info. They mentioned Acrysof natural at 21D chops 20% of blue, 35% indigo and 50% of violet compared to the non-natural IOL.
taurus, I had both eyes done, a little more than a month apart. The yellowish tint I mentioned was only visible when the folded lens was inserted into my eye. That's because I was looking through multiple layers. As soon as it unfolded, the yellowish tint was gone--and I mean gone, right there in the OR. All color values appeared normal to me, even though my vision was blurry right after surgery (they put a lot of ointment in there before and during the operation).
The reason I mentioned the 'several days' was that I was not among those who had magical clear vision right away upon leaving the hospital; I had some blurring and stuff for a day or so, but when I was able to be sure I was seeing things well enough to evaluate them clearly, I had basically perfect vision all the way, something I had not had for a couple of decades.
To sum up, with my reStor D-1 lenses, I'd have to say that I do not perceive any yellowing at all in either eye.
I suspect that slight tint the manufacturer puts in is not only to protect against blue light, but also maybe to simulate the sight of a normal 35-year-old, because at the age of 35, a lens has already begun to thicken and is slightly yellow. If you look back through the complaints about implants at this site, you will note that some people found the amount of blue they saw post-op as unnatural, cold, and disturbing. With the passage of time, we get used to looking through a lens that becomes yellower and yellower. I remember my father-in-law, who had cataract surgery in his 80s, remarking with amazement, over and over again, at how much blue there was all around.
Thanks a lot for sharing your experience. Basically you don't find the IOL yellow tinted.
But I am not sure I understand what do you mean by '... some people found the amount of blue they saw ...'
Do you mean those people using other non-yellow-tinted lens.
When I first read the theory about the blue-filter from the Alcon site, I have the following question. If this yellow-tinted lens mimic the natural lens of 35 years old human being to block 30% of blue, then people should see the same color between the implanted eye and the other eye without IOL.
Use the same logic, if a person implants a TECNIS iol or even a Acrysoft non-tinted IOL like SA60AT without blue filter, he should see the images looks brighter or more blue as compared to the other eye without any IOL.
What I mean is :
If the theory of Alcon is correct, the yellow tinted lens should NOT ONLY offer retinal protection. The patients should feel more comfortable than other type of IOLs as this Acrysof transmits the same light patterns transmitted by the natural lens.
On the other hand, patients should find visual looks a bit blue after implanted the other IOLs as more than usual blue light falls to the retinal.
NOTES: THE ABOVE DESCRIPTION WILL ONLY CORRECT WHEN THE ASSUMPTION THE ALCON HAS A CORRECT PATTERN OF HOW THE NATURAL LENS TRANSMIT LIGHT IS TRUE.
Does anyone see any report about patients with other IOLs feels a little bit blue ?
When Alcon's blue-light filtration feature was first introduced, rival manufacturers claimed that the yellow tint would cause all kinds of problems, including impaired color perception and sleep cycle disturbances. I could find no credible evidence to back up these claims. Subsequently, Bausch & Lomb introduced a violet-light filtration feature to their lenses, which allegedly provides protection against age-related macular degeneration. The benefits of filtering either blue or violet light remain controversial.
Taurus1203, keep in mind that the intensity of the yellow tint (and the amount of blue-light filtration) varies with the power of the AcrySof IOL. Lenses to correct nearsightedness have less tint than lenses to correct farsightedness. The yellow tint of your natural lens is probably more intense than what you'd find in any AcrySof IOL. I really don't think that the tint would make any perceptible difference in your vision.
I start to feel interesting to find out if the yellow tint may bring me more comfort than trouble. After the RD surgery, I had quite a severe light sensitivity and wear either a yellow/brown tinted glasses indoor and a dark sunglasses outdoor.
As you mentioned, my natural lens may filter the blue lights similar to the amount of the AcrySof filters. I am also thinking if I implant a IOL only filter UV like Tecnis, will that eye have a sensation of more 'BLUE' than the other eye.
Not sure someone implanted other IOLs can tell me if they have this feeling.
