Normally a doctor can correct for two things, focus and stigmatism. The new system measures 40 different parameters. So then they dial that into the laser surgery and poof you have better vision than any human has ever had.





    For those that worry about the 50 year outcome ... these doctors are not working from a clean slate. The "injury" from the laser is not that different from other types of injury that you may get on your eye. So they have a basis to know what the longer term problems will be.




    Interesting Scott is this new system going to be available within the next 5 yrs?

    I don't know. I read about it on slashdot. It's based on the same technology that they use to correct atmospheric distortions for telescopes. When I read about it they had a bench top system with an adaptable mirror to correct the vision. You look through it and it did a real time update of the mirror. They said the day time vision was improved but nighttime (low light) vision is a dramatic improvement.

    I love knowing what to search for



    I googled "adaptive optics for human vision" and hit a ton of links.





    This is from 2000. I'd be willing to bet some big time company is working on a product. It's a big D and little r.

    If I'd just read

    While the work is still in a research stage, eye-care giant Bausch & Lomb has licensed the technology and is working with University researchers to commercialize it.

    Stories like this make me not want the surgery.




    I do carry as well a bottle of eye drops everywhere - but I did it before too. Mostly for allergy. I'm too allergic to wear contacts etc. So after 30 mins normally in spring the eyes hurt so much I had to remove the contacts. Sometimes even a few minutes.



    I had the surgeries (1 for each eye) 4 years ago (can't believe it's that long already). The eyes healed well, first I had the surgery in 1 eye, then a month later in the second. My vision is good enough to allow me drive legally without the glasses, and depending on the light and my tiredness/wakeness level I can see very clearly, or see slightly blurred (in dark).



    The only negative side is my eyes are huge, the pupils diameter goes to 9-9,5 mm in the dark. That's abnormally big. The surgery could help up to 6-7 mm from the center, so in dark I have a double vision. I see the clear image, and e.g. a traffic sign - I see like a big huge light behind it, that'd be like the old picture (that was 4-5 times as big and very blurry than the original image). I can still see the signs clear in the dark - I think the only limit is I probably could not become a commercial pilot.



    The good sides are far more than that negative side. The cost would be another negative sisde, but if I broke my glasses every 1,5-2 years, the new glasses always cost .. so to eliminate the cost of the surgery, it wouldn't take that many years (under 10 in any case, I didn't have an insurance or anything to pay it). Now ... I can see my fingers and toes without glasses. I can see without glasses, I can buy any pair of sunglasses I like. I no longer need to bother with the pain of the contact lenses ..



    I still use the eyedrops. I did before too. The surgery had no effect on my being allergic or my eyes getting dry in winter climate (hooray for British weather.. heh). I'm happy with it.



    Though I no longer look that smart without those glasses ...

    pretty bad. i wonder if it is out of the range of the surgery?




    it's not.



    there are 3 types of surgeries commonly made. PRK, Lasik, and inside the eye corrective lens. The corrective lens can fix up to -40 d visual problems (but is more complex, so it's normally used btw. -8 and -40 d strengths. (I don't know the plus equivalents, it's used for those as well).





    I don't know what mine would have been in those 20 / something numbers. I just know I did not see my fingers or had no clue how many toes I had without glasses. And they did not have to use that corrective lens thing on me.

    wow, is the grape diet thing real? CAn you give me more info on that? I'm sick of wearing glasses and contacts and the laser eye operation just still has too much risk.



    It's not really a "diet" in the weight-loss sense, but basically for myself I bought a couple of bottles of bilberry and grape seed extract, highest potency I could find, and took the pills as directed - which was IIRC three times a day. The better part was eating the red globe grapes with seeds, usually a half-bunch a day; I was not afraid of eating as many grapes and swallowing the seeds as possible as I figured fruits cannot hurt you.



    All I did was investigate holistic options, and just started into them. No magic number for doses, just consumed. In my googling, the bilberry was something the British RAF was looking into for improving night-time vision of their pilots back in World War II so I figured to add that to my grape-oriented regimine. There might be even better things out there with more research. This for me was a trial with nothing to lose and it worked. I noted my astigmatism as I am not sure if this would help near-sighted, far-sighted, whatever else.



    As I said earlier, your mileage may vary. PLEASE, do the research and make sure there are no issues regarding a sudden increase in anything that is consumed. Someone once told me grape seeds cannot be digested correctly and may interfere with the stomach, but this guy was a bodybuilder who took insane amounts of protein, so it may be related to that...
