How are LASIK and LASEK?

These days, there are many people who have undergone LASIK or LASEK surgery, right? I have almost one person around me who has done it. However, I still wear glasses. I want to have LASIK or LASEK, but I'm too scared to do it. If I had the surgery, it would be a completely new world~ With advances in medical technology, side effects should be less, right? Should I try it this year?
