Curious for anyone who understands the science/optics here... if/when this is available, would it still have the downsides LASIK (and contact lenses) have for older people where you no longer need distance glasses, but now you may need reading glasses, when you didn't before, etc? Or might this be able to improve both distance vision and preserve nearsightedness/reading vision at the same time? That tradeoff is the reason I personally never got LASIK, as it was just trading one pair of glasses for another, for me...

There is no case where you need reading glasses and weren’t going to before lasik.

That’s a myth and completely unrelated.

You need reading glasses because muscles at your eyes lose the ability to pull tight and focus up close. LASIK is a correcting of the lens. Entirely different systems.

If you put off lasik because you thought you would need readers, congrats, you could have been seeing sharp at distance this whole time and will likely still need reading glasses.

There are several errors here. When the eye ages, the lens stiffens, effectively decreasing the focal range. For nearsightdness, Lasik alters the cornea and moves the relaxed focal distance outward. It's possible that a nearsighted person wouldn't need reading glasses even as their focal range decreases, but would after Lasik.

I’d love to see peer reviewed large group study for it. Plenty of claims, and never seen actual evidence. There may be some, I’m open minded.

I think bad to the years before lasik and remember the thousands of pairs of readers I saw older people with.
