Can you provide more details on this? A cursory search doesn't turn up anything especially alarming. The only source I could find that was alarming is this[0], which I don't really trust because it reads a bit like anti-vax literature ("see what they're hiding", etc.) and is very old (all sources they cite are from 2009 or earlier). My understanding has been that the procedure has improved dramatically in that time in both cost and safety.
One of the big ones I had found was risk of chronic dry eyes being really high, but that seems to be with PRK surgery and not LASIK. Rates of long-term dry eyes after 12 months for LASIK appears to be 0.8% according to the papers I found, which you could argue is pretty low.
I wouldn't discount the idea that modern practices and equipment works a lot better. A lot of the horror stories I do find are older, like you mentioned.
A year ago I came across Todd Becker's method to cure myopia here from HN as well. In case interested to check it out: https://www.youtube.com/watch?v=x5Efg42-Qn0
There's also a PDF from a different guy with some practical guide. Feel free to email me at denny at nusantara-cloud.com if you want me to share it.
Would you mind going back and adding that in your original post, as you've got pretty big unsubstantiated claims about LASIK.
2. I still haven't changed my general opinion about LASIK: it seems too much like a "convenience surgery" to me, i.e., most people who get it have correctable vision with eyeglasses/contacts. It's also not hard to find stories from the minority of people who had complications and regret it.
3. My original comment came with this disclaimer: "Remember to listen to your doctor over random people on the Internet, including me."
But with PKR you also have wait like up to a month before vision is clear again, versus lasik giving mostly clear vision within like a day or so. So with PKR long term it is less physically vulnerable but it puts your vision out of commission for a week or two atleast.
Is I believe the original
I don't think the advice to avoid contacts as a baseline recommendation is the takeaway of the comment you replied to, that advice pertained to that person's specific medical situation.
Also, personally, I don't believe it's the type of screen that's problematic for long-term eyesight. What my optometrist told me is that we weren't really evolved to be looking at things close up for long periods of time.
I don't think e-ink versus backlit screen is the issue – certainly, our eyes take in a lot more ambient light from not-screens during the day compared to the weak little LED light on our screen.
The real issue is spending 8+ hours a day focused on close up objects. Take frequent breaks where you are looking in the distance, go on walks, etc.
Remember to listen to your doctor over random people on the Internet, including me.
