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!

Laser eye surgery is “just” reshaping the cornea on the front of the eye to change the lens geometry. Injuries and illnesses of the retina or optical nerve are “further up the line” and are related to the connection to the brain.
