Not scientific but I only had PRK as a choice. And the healing time is a lot more than the LASIK procedure. Although my doctor told me that it "could take a few more days".

Took me a week until I could look at a computer screen with a ridiculously large zoom level and only for a couple of hours total per day. At about 3 weeks, I could look at a computer screen at a lower resolution but no more than 4-5 hours total.

As for risk; from my reading the greatest risk in both are post-op infections which are a concern with any procedure(even sampling blood). The others weren't really something to worry about. With LASIK, there's also a risk of flap detachment. But that could happen even with a healthy flap if the force is big enough.
