In fact, to the contrary, with wavefront correction TransPRK you can look forward to better night vision than before!
The reports that you have read online are probably reports on early PRK surgery that precedes modern wavefront TransPRK. There are no scientific studies to date stating that modern TrransPRK can cause poorer night vision.
My experience is that patients with pre-existing night vision complaints may still have similar complaints after laser vision corrections be it LASIK or TransPRK. This is because these patients may have inherent contributing factors such as abnormally large pupils in the dark or abnormal retinal sensitivity.
