>>19222Lasik works by using the laser to thin down the cornea of the eye; it only works on short sighted people because their eyeball is too big for their head (axial length) so light falls ahead of their retina, making them blurry.
I'm longsighted which means my eyes are too small for my head, so all Lasik would do would be to make me even worse. It is a good surgery for short sighted people, the only side effects are that they might get it slightly wrong so you'll still need glasses for a tiny leftover prescription to see perfectly because the eye isn't like a computer so you can only estimate whether it will work with near perfect success, dry eye, or in very very rare instances keratoconus.
You will always need reading glasses when you turn 45 because that's a separate issue (the ciliary muscle of the eye weakening), so always keep that in mind because Karens never seem to understand that idea.
