Why can’t laser eye surgery cure blindness? Eli5
I’ve been told I’ve got diabetic retinopathy and it’s getting worse. They mentioned potential ‘sudden vision loss’ and I went on a wild internet search and ended up here. Can someone tell me how laser eye surgery can make eyes see perfectly when they usually need glasses for severe vision impairment but can’t do anything for full vision loss? Please. Like I’m five. Thanks!

Because it’s not magic. It just adjusts the focus point of the lens system inside the eye, it can’t grow back stuff that is dying off. You can keep polishing the lens of a camera with a broken sensor, it just becomes a slightly shinier paperweight.
