I wrote a hub on Lasik. I researched it in depth because I was thinking of having it done myself. After looking into it, I decided definitely not to have it done. There's a lot of detail in the hub if you are interested. It's called "Lasik Laser Eye Surgery - The Truth". If you'd rather research it yourself, look for scientific papers by the FDA or other organizations which are not in any way benefiting financially from the industry - i.e. look for scientific facts and ignore the sweeping platitudes of those selling it. If you ultimately decide to go through with it, you at least should know what the risks are.
