This is a question that many visually challenged people, including myself, have always wanted to know. I know that some people have sworn by this procedure and others say that they have some side effects. Not to even mention that this surgery cost is somewhere in the ballpark of $3000 bucks. My personal and specific apprehension about the procedure is that does it last forever? Dr. Mercola is a physician that has a great online video series where he answers various questions that people send in. This question, along with many others, are answered quickly and in a manner in which the average person (me waving my average flag here) can completely understand. Enjoy the video and leave some feedback. I will post more if everyone like them.
