It helps to understand the benefits of the procedure to understand why folks would undertake the risk... I had correction at -6 diopters, which is equivalent to about 20/500 vision. My near vision uncorrected was bad enough that the focal distance was closer than the distance needed to resolve 3D vision. This means that to read my phone without correction, I had to close one eye and hold it in front of my face. Further, I was developing an astigmatism, which results in double vision, even when optically corrected (glasses can fix this, contacts do so poorly).

I got PRK in Vancouver, BC for less than $2K USD. Recovery took about 5 days to functional vision, and maybe 1-2 months for complete recovery. It is a world of difference. I wake up and can see the world immediately. I can go hiking/camping without gear that requires a sanitary environment just to wake up and go to sleep. Cheap sunglasses work. I can participate in sport with no notice or prep. I can swim without eye protection. My day-to-day experience is dramatically improved.

If you don't perceive the benefits, LASIK/PRK may not be for you. For some people, though, life with glasses or contacts is a noticeable burden, and correction can provide measurable upside. In these cases, it can be well worth the perceived risk.
