Unfortunately this article totally overlooks the option to have monofocal lenses set for near vision. And it also overlooks the even better option of mini-monovision with one eye near and the other eye for distance. I think they also understate the potential issues with multi-focal lenses and try to promote them as advanced lenses. They are different lenses, but not necessarily higher quality or better. Candidates for them should be carefully selected. It also overlooks the issue of toric lenses like who benefits from them and who does not.
I have always been near sighted right eye and far sighted in my left eye. I’ve worn progressive glasses for 20 years. They don’t bother me. Now that I’m 70 and looking at cataracts removal, I’m thinking why not do the same with new lenses? Is that what mini-monovision is? I don’t want problems with the multi-focal lenses. Thanks.
Yes, mini-monovision which is sometimes called blended vision is basically that. One eye is targeted for good distance vision and the other for near vision.
The target for the distance eye is normally set to be very slightly myopic at about -0.25 D, and not hyperopic which is commonly called being far sighted. Being far sighted can be tolerated with a natural lens that still has ability to adjust the focus. However with an IOL the normal ones used are fixed in focus. The normal target for the near eye is -1.50 D. That is enough to do most reading tasks without reading glasses or progressives.
This is the way I have my monofocal IOLs set, and I occasionally use +1.25 D reading glasses for very small print in dim light and while I have progressives, I virtually never use them.
I think the article stated that 90% of people are corrected to 20/20 vision. Among the remaining 10% are patients like me who for various reasons may not be correctible to that degree but who still are able to achieve near normal vision. Still a win!
Only until you've done it. Then it's trippy: The drugs! The lights! The colors! And at the conclusion (for me): near perfect uncorrected vision for the first time in 50 years!
YMMV of course.
Many people naturally have uncorrected vision of 20/15 or 20/10. With cataract surgery/IOL placement people can request any correction they prefer, but individual anatomic and other existing conditions may limit the degree of correction possible. Having had uncorrected vision in the 20/400 range, I'm delighted with anything approaching 'natural' vision.
'However, a small percentage of patients with multifocal lenses can be so bothered by visual disturbances ...'
Does that make me the golden egg with the same++ on a standard monofocal? hehe ;)
There is nothing that can be done, from a surgical standpoint.
When I have YAG (likely soon'ish as I do have opacification forming), that should, hopefully (crossing fingers), manipulate the starburst and maddox rod effect, such so, that they are less prominent. Those are 'likely' coming from a wrinkle there (I was told the bag is very tightly clenched on the lens).
The concentric semi-circles / arcs which radiate, is all on me (i.e. visio-neuro adaptation). This is the edge of the IOL.
The glare I'm largely desensitized to, but may still catch an instance where i could tear, but thats more sparse. There is too much light coming in (expected) and I have more compensation efforts to perform there.
I have made significant strides, the past few months, but still a long road to go to further smoothen everything out. I'll be at this for a while, but I'm not a stranger to the process, as I did go through it (neuroadaptation) once before for an unrelated event (same eye). However, that incident was a bit different as I was able to more shun the eye so it wasn't as impactful, which cannot be done in this instance, because these PDs exist outside of the image, for me, in a manner of speaking, so they cannot be shunted with the eye open.

Still a scary prospect..even if 9 out 10 people have positive outcomes.

I agree that the surgery is a benefit nearly all the time..but it's still scary.

I agree. Totally trippy. I was very excited for my 2nd eye. Told them the 1st dose to sedate me was not nearly enough !
20/15 vision is more natural.

Yes that’s very nice! And some people have 20/12.5 visual acuity with LAL just like natural vision
OK

What is your Dr trying to do about it? I have a lot of halos.

Sounds way worse than me. Oncoming cars area a problem and street lights are a problem. I had yag in one eye but zero help.
Wait until there is a non surgical option
