People here are rightly pointing out that there's still room for improvement with this (and almost any) kind of surgery, and the article talks about the accessibility challenges of making procedures like these more widely available, but after reading up on the history of this procedure it's hard not to see modern surgical techniques as a kind of man-made miracle. Great read.

It's nuts to read this technology has only been around since 2008. It seems like it's been around forever.

I'm not that old, so that's part of it. And also, 17 years is a long time in tech.

Regardless, it is a modern miracle that there's been this much progress in that short of a time period.

The article stats a 95% success rate - which doesn't seem great, but <0.5% of incidents have serious complications, most of the other 5% are temporary minor complications.

Eye surgeon here: FLACS isn't really that amazing. I would actually argue that a man made incision using steel or diamond (yes, diamond) is better than the incision made using the femto laser for long term safety/sealing. Number of studies have borne this out.

95% success rate seems low. you need to define success in this scenario. Are we aiming for 20/20 vision outcomes? Just getting the cataract out in full?

It's here already - at least for the developed countries. It's both thanks to this multitool used to handle the surgery - destroying, removing natural lens and replacing it with an implant, and technology that allowed creating customized intraocular lenses pretty fast.

My mother had her eyes done 2 years ago with one month break between. I did set timer on second surgery and it was just 20 minutes once she was inside. The only thing we had to care about were drops administered 4 times a day before and after the procedure - for once multiple alarms on my phone were useful. And of course control visit with dressing removal that happens for every patient on second day.

In my city a duet of two doctors runs an ophthalmology clinic and seems they have some good contracts with health services because they're always busy and have shorter waiting lists than clinic at our local hospital. Both women handle a queue of about 20 people and each weekday is dedicated to a different issues, with serious surgeries reserved for weekends.

I ask one of doctors if failed cataract surgeries happen because I was concerned before the first time my mum had it. She said that these are extremely rare but if a patient needs another it happens again pretty fast. The issue might be with lens that moved inside due to e.g. patient activity shortly after the procedure.

I do remember some short documentary about probably an Indian surgeon who treated eyes of North Korean elderly people. He also visited other places around the world as sort of personal goal to give new eye care technology in places where is needed but socio-economic conditions do not allow it. I'll try to find that unless someone happen to know that man's name.

His name is Sanduk Ruit and he's Nepali. A huge inspiration!

The miracle is when they put a _graduated_ lens and you get cured of cataracts and myopia in a procedure where you are awake and can perfectly ntoice how while the lens is being inserted the blinding lights on top of you become more and more defined.

It's nothing short of a man-made miracle but I have to say it's also very umconfortable and stressful for the patient.

The surgery is not fun. The worst part was the cannula for the subtenon block - not painful, but my anxiety at something being poked into my eye socket went through the roof. My sister opted for sedation after she heard of my experience.

The second operation was easier as I told the surgeon about my reaction to the subtenon block and he put some topical in the right place making it much easier. However the residual anxiety from the first operation remained. All that said, I've had rougher times at the dentist.

I opted for optimal vision at arm's length with a monofocal lens. We spend most of our days around the house. Bifocals with plano below work fine for outdoors, driving and flying (check with your aviation doctor before lens selection as aviation authorities are strict in what lens options are allowed). The depth of field has turned out better than I expected, but I use 1.25 diopter drug store readers when I'm using my tablet at home and put it at arm's length in the coffee shop.

The results are absolutely wonderful and I feel gratitude every time I step outside.

I had it done about eight years ago... there's nothing quite like waking up after a fifteen minute procedure and seeing better than you have without correction since you were five.

> It's nothing short of a man-made miracle but I have to say it's also very umconfortable and stressful for the patient.

I think I must be strange, either in my reaction to the stress or the way I chose to manage it during my surgery.

I explicitly wanted to be somewhat awake during the procedure to see what was going on (how many chances do you get to see your lens emulsified from the inside)... and I remember having short conversations with the surgeon during the procedure. (She'd been concerned about zonular laxity, and we discussed during the procedure that she didn't see evidence.)

This is not something I'd want to reproduce if I didn't have to, nor would I suggest it as a general approach, but given that it was necessary for me, it was amazing to see it first hand.

My second procedure (second eye) was a little more stressful than the first, but for me all the material stress (which was significant) was in the run up and anticipation.

> it's also very umconfortable and stressful for the patient.

This is what concerns me. If someone took a blade to my eye, I would be screaming, vomiting, and thrashing until I lose consciousness even though my rational brain knows the surgeons are helping. Are there options for the irrationally mutilation-averse people such as myself (like general anesthesia) or are my options just go blind or re-enact a Saw movie?

It sounds like it must inevitably be uncomfortable and stressful—why do they do it with the patient awake?
