Patients who have a new type of lens implanted in their eyes during surgery for cataracts or to correct their eyesight have excellent or good vision over distances both near and far, and often no longer need spectacles for reading.
Research presented evaluated outcomes for around 200 patients in 17 sites in Europe and Asia-Pacific who had surgery to implant the TECNIS PureSEE.
Data were available for 238 patients at the time of the Congress, making it one of the biggest studies to report on this type of lens so far. The findings showed that the EDF presbyopia correction IOL, on average, provided excellent distance, very good intermediate, and functional near vision without glasses, with little refractive error.
Nearly all patients (96%) reported needing glasses 'none' or 'a little of the time' for distance vision; 93% reported this for intermediate distances, 62% for near distances, and 85% for overall vision.
He said, "The PureSee EDF IOL gave patients excellent distance, very good intermediate and functional near vision, which resulted in high patient satisfaction with less need for spectacles.
To enable a patient to see objects both near and far, their surgeon may offer them a choice of lenses, such as: Monofocal lens Multifocal lens Extended depth of field (EDF) lens
"The difference between some of these lenses and the EDF presbyopia correction IOL that we used in this study is that it is a fully 'refractive' IOL, meaning it uses variations in the lens curvature to focus light at a single distance. The surface of the lens is smooth and you don't see bumps or rings," said Prof. Findl.
"This means you have better night vision and don't see halos, starbursts, glare and other visual disturbances that can occur with other lenses."

My doctor put a little different lens in one eye than the other. Whatever he did it worked for distance and reading.
I'm 71 years old, and have had cataract surgery for both eyes this year. At worst, I'm 20-30 in both eyes, I'll wear readers when working, or at the computer. Being able to see that magnificent full moon last week was exhilarating!!!
It took nearly two years to get the first surgery done, as there were complications from shingles a few years back. Some of it worked its way into my retina, but I have a great doctor, and we got it cleared up.
I don't know what lenses were used, but they were an upgrade from the standard lenses. Don't regret paying $800 each for both lenses...my bonus at work covered the cost.
I now feel comfortable driving at night, too.
I’m having this surgery done in Nov
And Dec. But medicare/medicaid doesn’t pay for good multifocals. Thousands would have to come out of my pocket...Ain’t gonna happen. I have a choice of being near sighted or far sighted, and will still need glasses. I chose near sighted because though I drive, it’s not that often. Most of my world is close up. In my younger years, I was near sighted in one eye, far sighted in the other. I’m a little nervous of what to expect.
PureSEE. Data were available for 238 patients...
You really have to know where to look, in order to PurSeev.
😉
And on Mars, Pursee is short for Perseverance.
😂
Of course, Percy is the perky lil rover that found the leopard spots, which NASA was all over for the best evidence for Life on Mars to date.
>>> The story of this potential biosignature began in July 2024. After years of exploring the floor of Jezero Crater, an ancient lakebed, the Perseverance rover drove into Neretva Vallis, the river valley that once fed the now-dry lake. There, it encountered the peculiar Cheyava Falls rock within the Bright Angel formation — a set of rocky outcrops along the northern and southern edges of the river valley. The rock was immediately striking, adorned with small, dark “poppy seed” flecks and distinctive, white, ringed “leopard spots.”
Initial analysis with the rover quickly confirmed the presence of organic molecules — carbon-based molecules that form the basic building blocks of life. But the true significance lay hidden in the chemistry of the spots themselves, which contained minerals thought to indicate the presence of microbial life billions of years ago.

I had cataract surgery about 3 years ago. I had to have it done, because one of the cataracts was right in the middle of my left eye. What they don't tell you before you have the surgery, is that in a majority of cases, you will have to go back and have a laser procedure on both eyes to destroy cells that eventually develop on the lenses and blur your site. It's a one time procedure, and they only do it one eye at a time on different occasions.
I can see 20/20 distance, but shit for anything else. Medicare paid for the frames I picked out, but they did not pay for the graduated lenses I needed for computer and book reading. I paid $350 for them, and I can't wear them to do either. It's because the size of the areas in the graduated lenses that I view from when using the computer and when reading books, isn't big enough to allow me to see clearly. I had to go out and buy reading glasses in two different scripts that I use when I'm on the computer, and when I read books.

I had a corneal transplant in June. Helped a little but not much.
She now has "no glasses" vision, both near and far, for the first time in her lifetime. Before the implants her far vision glasses were reaching the point where they had maxed out.

There is a very similar lens, Clareon, PanOptix Pro just now available in the US. It’s new enough that not all providers are aware of it (or they have contracts from other guys).
This is a technological advance from earlier Pan-Optic.
...I can see one big caveat.
...Study participants were eligible for inclusion if they were over 40 years old and presented with preoperative astigmatism ≤ 1.0 diopter (D). Patients were excluded if they were over 85 years of age, had an axial length > 26.0 mm or <22.5 mm, a history of prior ocular surgery or trauma, ocular abnormalities, or diseases other than cataracts that could affect postoperative visual acuity. Patients with an axial length of >26.0 mm were excluded based on prior studies reporting an association between absolute prediction error and elongated axial length [16,17]. Patients with intra- or post-operative complications were also excluded. One-to-one (1:1) case matching was performed, and the control eyes were matched for age (±5 years)....
FYI.
My doc said that I was looking through a ‘dirty window’(right eye). Good description and it’ll get done before it becomes a problem. About glasses... They have saved my eyes often. Flying metal chips, rocks, etc. I’ve worn glasses since grammar school. Probably will after eye fix.
One lense does nearsightedness and farsightedness correction? Are they like bifocals with two lenses?
I need cataract surgery, right eye is very bad. I have worn glasses since I was 12, they blocked me from following my ambition to follow my Dad as a Navy Aviator. I sure was not going to sit behind anyone and so let it go.
Now, with cataract surgery in the plan and the opportunity to spend the rest of what is left of my life without spectacles and all that goes with that I am particular. I want a perfect outcome and so continue to do research to find out how it can be done. Measurement precision and placement in the “bag” seem to be the highest critical success factors. Both are dependent on the machinery used and the doctor using them.
Few I have spoken to have used the multifocal lens and those that do are happy but so far have seen halos with night vision. All other accounts with conventional lenses are glowing. I want to see the stars sharp and clear like I never imagined them! Too bad this lens is not yet available here and the shut-down will be yet another reason we can’t have it.
Get your prescription and buy the frames and lenses from Zenni Optical. I have used them for years and never had a bad pair of glasses. I can be accused of going wild since I buy no line bifocals, computer glasses, reading glasses (that I hardly ever use) and single vision glasses in sunglass and regular prescriptions.
None of this will do a bit of good now until I get these cataracts taken care of. That technology is improving so much and so fast but I don’t want to wait too long past this year to perhaps enjoy life without these glasses that have made permanent divots in my skull behind my ears, slide off my face when I sweat and other irritations. Never more to pick up and put on my glasses when I wake in the morning, unimaginable! I just don’t want to be disappointed.
Appreciate the suggestion, but no thanks. I'm 78. I'm not spending any more money on glasses for whatever time I have left. I can see long distance without glasses, and will depend on cheap over the counter glasses to use with my laptop and book reading.
" I just don’t want to be disappointed."
Unfortunately, there's no guarantees on that.
I wonder what the difference is between the older pan optic and the newer version that has those eligibility exclusions.
Probably a lawyer.
Those restrictions make me ineligible.
A different brand of apparently the same technology is now available here. Clareon PanOptix Pro. It’s new enough that not everybody is using it yet. My eye institute doesn’t have it yet.
My right eye is getting the distance lens next week. I’m holding off on the left eye because I can see distance and close with it. I don’t want to lose that ability. I’m apparently not eligible for the new lenses.
