Laser eye ops could ruin sight - Health - NZ Herald News

"Concern has been raised about the long-term effects of laser eye surgery after a new study has shown that tens of thousands of New Zealanders
are likely to suffer defective vision from the surgery in their later years."

"Anybody who's had their cornea planed would be eaten by a lion at the water hole...
If there was serious break-down of law and order, they would probably get shot before the others because they couldn't see so well.":lol:

After Joe Duffys recent expose one would be very reluctant to have this surgery.


Is the proliferation of laser eye surgery clinics on a par with the head shop problems I wonder.?

Are there any regulations applicable to this murky and blurred area of latest fad whizz techno spin.?



Of all the senses eyesight is regarded by many as the most important and the long term consequences of this,
in the vast majority of cases, optional procedure , are not known.

Be afraid, be very afraid.

FM, for once we're on the same wavelength.

That is the reason I've steered clear of laser eye surgery - we just don't know the long-term effects 20, 30 or 40 years down the road and no one can tell us with confidence.

I know plenty of people who have had their eyes lasered in recent years and swear by it. My brother had it done and had fierce problems in one eye for a couple of months afterwards although it's settled down now and things seem grand.

But when I asked them what effect it would have 10 years down the road they just didn't know - and don't seemed to have been told with any degree of certainty.

Tempted as I am to go for it, I'm just a little too cautious to take a chance with my sight - so I think I'll stick to the old specs and contacts.

Anyone tempted to have this surgery should wait for better advances, like the Light-adjustable lenses (LAL)

No need for specs: eye implants offer ‘super vision’ - Times Online

The lenses, already in use in Germany and the United States, cost £600 each, ten times as much as standard IOLs. They are being offered for the first time in Britain to private patients having operations for cataract or presbyopia — age-related deterioration of sight — at the London Eye Hospital.


*Bobby Qureshi, a leading eye surgeon who has so far used the technique in ten operations, said the total cost of an operation and adjustment would be up to £3,000 per eye, “but patients think it is worth it”.

“We have the potential here to change patients’ vision to how it was when they were young,” he added. “The technology allows us to make adjustments after the lens is in place and healing has occurred.

“The change is so accurate that we can even make the lens bifocal or varifocal, so as well as giving them good vision at distance we can give them good vision for reading. They won’t need their glasses at all.”

Mr Qureshi said that patients could achieve “better than perfect vision” because the adjustments could account for natural imperfections in the eye, known as high-order aberrations, that can subtly affect vision.

“This is probably the greatest advance in lens technology since the first ever intraocular lens was implanted 60 years ago,” Mr Qureshi said.

I had it in November 2005. 100% success. No complications at all.

That's fine and dandy but what about the effects in 10 or 20 years - have you no concerns about possible impact on your vision?

Can you be sure that you won't suffer sight loss further down the line due to the surgery?

I would be extremely retiscent to have laser eye surgery. Longitudinal evidence as to its safety simply is not available.

I'm quite happy with speccy my four eyes thanks very much. A nuisance sometimes when I misplace them, but other than that no problem.

The main issue is that either LASIK / LASEK & IOL's involve surgery, and surgery is always a risk as its quantifiable in terms of how the average person responds to a procedure, but not each individual on a person by person basis (so to speak). I've had LASIK (which was great for me), but know many people who have had disappointing experiences, some are still wearing glasses. LASIK / LASEK have been around for more than 20 years now, and while there I dont know of any comprehensive independent long term impact studies, I certainly don't know of any results that suggest negative impact. Due to litigation possibility, if there was a problem I would have thought that the media would have latched on to any wiff of a story there....

My biggest regret was that I did not get it done sooner, wish I did it five years previously.

I was warned of the risks,plus I was also told that I would probably need glasses in my mid 40s like all folks. So it worked out at 1800 (net of tax rebate) to not wear glasses and contacts for at least 15 years. I'm not a big golfer, but it has made a huge difference to my game.

I might be a bit vain, but no different from wearing a sharp suit or having a good haircut.

Having said all of the above, I did notice that many of the staff & doctors at the eye clinic where I had my LASIK done, were wearing glasses...... which made me nervous.

Nevertheless, it really was a great benefit for me personally...

Exactly.

That is the critical question: the long term effects are not well understood or known.

There is a financial stimulus I suspect behind a lot of the ads on laser surgery.

I get a strong feeling that it is a question of reel the suckers in before the long term studies are concluded.

It is irresponsible and many people are, quite literally ,having the wool pulled over the eyes concerning these long term risks.

At least with glasses or contacts your bits are not burned.



Hopefully somebody might post any links to any long term studies.

The procedure has been on the go for some time now so the studies should be coming out.

I wear varifocal, 30 day contact lenses. Pop them in and that's it for 30 days - sleep in them too. Worn them for 4 years now.

Intraocular lens - Wikipedia, the free encyclopedia

It is still eye surgery and therefor invasive.

The eye is such a delicate and sensitive organ any kind of cutting /slicing invasion would give you the heebie jeebies.
You got it in one. I had the tests to see if I was suitable for (expensive) laser surgery (funnily enough I was) but the experience put me off even more.

One of the tests involves opening up the pupil or iris (can't remember which) to see how the eye reacts to light.

Fair enough, but it took about six hours for it to settle back to normal.

It was a very scary afternoon. I could not see properly even with specs, everything was blurred, I could not focus or perceive distances, and had no peripheral vision as I walked along. I bumped into a few people and objects and had the sound of car horns ringing in my ears all afternoon.

By the time I had my old (very poor) vision back I was glad of it and decided there and then laser wasn't for me.

Despite the temptation, I can't see myself revisiting that decision.

I'd be pretty vain too, but contacts don't bother me that much. As mentioned by others, it's the idea of what happens in 20 years that would worry me.

Tiger Woods had it done. I don't recommend copying Tiger, except on the putting green.
Personally, I find the operation he had to be a surgical enhancement to his natural vision - why it isnt considered cheating is beyond me, pharameutical enhancement is, so why not this?

In the larger scheme of things, there are risks in life, and I guess LASER eye surgery & IOL's are such. I got a massive infection once from contact lens, and couldnt wear them anymore without severe allergy. Contact lens are risky to eyesight also, due to repeated touching of eye and possibility of intriducing bacteria & viruses (most concerning of which is the cold sore virus). So only glasses offer true low risk. Things that are proven to damage our eyesight !!!!! No 1 is smoking..... causes bloodvessel damage all over body, most tragically blood vessels in retina (back of eye), leading to macular degeneration anywhere from 40yrs old on....

Fair enough.
The risks you refer to are all avoidable or reversable.

Laser eye surgery is irreversible.

Layers are sliced off the eyeball.

They do not grow back again.
