#2Misleading lede "Forget..."
Corneal Electromechanical-Reshaping (EMR) experiments suggest that optical correction of vision may someday be possible by reshaping the cornea via electro-chemistry and a corneal mold, rather than tissue removal. Animal testing shows promise.

Re: Safer, cheaper vision correction without lasers or surgery
#4Curious 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.

#6Man, lasik was the best $3000 I ever spent. 20/15 laser eyes for almost twenty years now. Traveled around the world, no contacts, no glasses, no missing anything because I just woke up on a train or stepped off a boat or a bus.

#7It would be interesting to know if this could work w/ my floppy and misshapen keratoconus corneas. I'd resigned to having corrective lenses for the rest of my life.

#8I know a guy for whom LASIK wasn't an option, he needed a lens implant. I wonder what the new method would make possible
Re: Safer, cheaper vision correction without lasers or surgery
#9Studies with promising early results like these, such as the tooth-regeneration study that is expected to complete its Phase I trial soon, really give me hope for being able to grow old while staying healthy.
It does make me wonder how long it'll take until we've reached the end of things to cure, and what might come after.
