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!

If you can’t see you can’t see. A laser can’t fix that.
Laser eye surgery fixes blurry vision, like a camera that has issues with the lens being out of focus. Fixing a lens doesn’t help if the camera sensor doesn’t work.
