The whole "needles in the eyeball" are just a stepping stone to something truly amazing.
Indeed. I was severely nearsighted all my life, after the cataract surgery I no longer need corrective lenses at all, not even reading glasses and I'm 62. My vision in that eye went from 20/400 to 20/16. Truly a miracle.
BTW, my retina surgeon said that my retinal detachment was a result of being so nearsighted; a nearsighted eyeball isn't perfectly round like a normally sighted person's eyes.
