I wonder how this compares to similar, but different procedures. I had PRK done 7 years ago, and it was probably the best $4000 I ever spent. It went perfect for me - no new issues. However, I did it one eye at a time, just in case!

PRK differs from LASIK in how the top layer of the cornea is removed. In LASIK, a flap is cut and peeled back, then put back in place at the end of the procedure. In PRK, the top layer is scraped off and has to grow back in, a process that takes several weeks and can be somewhat painful.
