Permanent changes can't be undone for newer advances and options that come out in the next 30-50 years.

That's an advantage of ICL over Lasik: the surgery is minimally invasive, and completely reversible (assuming no catastrophic accidents during surgery itself).

A 3mm-long slit is made at the very edge of your iris, and the lens is inserted, then unfurled in place. Reversing it involves pulling the little sucker back out, easy-peasy. I've had that done, during cataract surgery.

It's not risk-free, but it's ostensibly MUCH safer than Lasik. We don't have enough data to make that a stronger certainty, though.

Sweet, thanks for the name of it, when I was learning more about it, I was trying to think of what this was called. I'm surprised it isn't more common like PSK/Lasik.

There's some interesting Infrared/LED light stuff coming out about eyesight repair too.

		For one, the US only legalized ICL surgery in the 2000s. Lasik had a big headstart.
