In 1948, Spanish ophthalmologist Jose Ignacio Barraquer Moner was fed up with glasses. He wanted a solution for blurry vision that fixed the eye itself, without relying on external aids. The surgery he eventually devised was called keratomileusis, and his technique focused on reshaping the cornea what we now know as LASIK. So how does laser eye surgery actually work?

This is fake News. The problem dosent lie in the cornea. If it did people would be nearsighted since birth. The cornea doesnt change shape through out life. But nearsightedness still progresses. Please get your science right. Its a problem with ciliary spasm and and then with axial elongation.

His vision will not come one day soon. The operation is still ridiculously expensive for your average person, even in countries with pretty decent wealthyness and good public healthcare. It's thousands, not even hundreds.

My uncle got laser eye surgery which worked at first, but a year later his vision was even worse than before he had the surgery. What goes wrong in these cases? It has happened to more people

Because My vision is so so blurry to the point where I can't read legit anything more than 3 inches ahead of me, I was thinking of getting laser eye surgery, should I get it?
reply

I've heard that the kornea is the most sensitive part of the body and can testify that you don't want someone cutting in it. That hurts too hard but is better than going blind
reply

aight so imma just. er. cut your cornea out, throw it in some liquid nitrogen, and um, sew it back onto your eyeball, okay?
Patient: yeah, I don't see why that would hurt

Here's why I'm so excited about the future of cybernetic enhancement. Imagine how precise a human hand could be with robofingers of this caliber.

got Lasik done on both my eyes for 221 each, wonder how much the first patients paid for the new technology? probably thousands per eye.

Had severe astigmatism. Underwent one of these (called Contoura Vision) about 6 months back. Changed my life. Thank you Jose my man.
