> I've always been a little surprised why we haven't figured out a treatment for myopia beyond LASIK, e.g. some way to manipulate the muscles around the eye.

Generally the reasons behind myopia are changes in the shape of the eye or the lens, not something the muscles are doing wrong. (And a contributing factor with age is the decreased flexibility of the lens over time).

Most naive expectation is if myopia changes the shape of your eyes, just squish them a bit!

You joke but there are orthokeratology lenses which do just that. It's a contact lense worn overnight which compresses your eye during sleep.

To people considering LASIK I want to say try ortho-k first. You'll get the sharpness, the halos and the whole experience but at least it will be reversible. I've been on ortho-k for around a decade.

That'll squish the lens, but the overall shape of the eyeball is what causes the myopia in most cases.

Tecnically the crystaline lens is in an anterior chamber inside your eye, so these contacts can't really squish the lens itself.

These contact lenses are squishing against your cornea. So in actual fact an anterior portion of your eyeball is being re-shaped.
