Feivel, I too would not advise it for those who want it for cosmetics only.
Yet, most surgeries are for enhancing the quality of life but and are not for life threatening medical reasons. Many times when these surgeries are not successful, the patient is a lot worse off than before surgery. Some examples: cosmetic surgeries; orthopedic surgeries (hip,knee,back,carpal tunnel,arthritic,etc); tonsils; adnoids; bunions; teeth; etc.
What about the eye accidents that occur when people are wearing glasses and lenses as was mentioned above?
The point is that people make choices for various reasons. They can choose to take medication for the rest of their lives and the risks that are associated with that; or that they can opt for surgery which is a different risk.
Just as there are sites that are con; there are also sites that are pro. In any case, anyone thinking about doing lasik, should research thoroughly and speak and to those people who have had it done.
