If it makes you feel better, your dry eye is more likely caused by genetics than it is PRK. Many people end up with dry eye without having had any kind of laser eye surgery. I highly recommend putting some Hylo-Night / VitA-POS gel in just before bed. It lasts well into the next day.
Yeah it's probably a combination, which might explain why my experience isn't the norm. Ever since I had it done, any poke, foreign objects like sand, etc. is much more painful than before, so the pain from dryness gets amplified. I've used eye drops and gels, but the most effective thing is just avoiding things that mess with electrolyte levels, like alcohol, medications, and certain foods.
