The video below gives a good background on the biology of the human eye and describes PRK laser eye surgery.  It will give you a better understanding of what the different laser eye surgeries do to the eye.

Some vision specialists and eye doctors might disagree with this assessment.  Lasik has been around for 12 years and has gained in popularity, especially in places like Colorado and Los Angeles.  Lasik eye surgery is becoming more and more ingrained as a legitimate procedure and is seen as a valid health expense.

People in LA may find other things to give up before they decide to forgo LASIK (which can be affordable and helpful for the right candidates), if they need to procedure.  Many people seek to live without the hassle of glasses or contact lenses, which is a reason the Lasik operation is a very popular one.
