How does laser eye surgery work?
Summary
José Ignacio Barraquer Moner was a Spanish ophthalmologist and he was a pioneer of laser eye surgery. It can correct refractive errors: imperfections in the way the eye focuses incoming light. It’s called Keratomileusis and its surgery is known as LASIK. (laser in-situ keratomileusis) We feel scared of eye surgery, however, it’s accurate enough to etch words into a human hair and the technique is currently about as likely to damage your eyes as wearing daily disposable contact lenses for one year. It means, l don’t want to say, if you use contact lenses over one year, your eyes will get damaged more than surgery. The process takes less than 30 seconds for each eye. If its surgery operates your body, it’ll be too small to feel anything thus l think you won’t feel any pain. The technology can restore not only myopia (short-sightedness) and
hyperopia (far-sightedness) but also presbyopia (aging eyes). The problem seems to be only expensive, right?

Barraquer was fed up with glasses. It led to founding great surgery. However, l think that it’s important for people how to be looked more than how to look.

It’s because when pretty girls and good looking boys wear glasses, people rashly get glasses like being them and laser surgery will be used for faces more than eyes. People want to be beautiful more than they can look at something well. I think so too. I use glasses because it must cover wrinkles on my face and my face itself. People must see my glasses before they know my face. Hahaha
