From my experience it was hell of a whole week, specially the first 5 days. And every kind of light was aggressive for me.
My eyesight took ~3 weeks to be able to read properly on screen without zooming 400%.
I didn't freak out because my doctor told me that the healing process really depended on everyone's body.
2 years later I have absolutely not regrets from doing that surgery despite probably still always reminding myself as one of the worst week of my life during recovery.
First 30 or so hours were pretty inconvenient: dry eyes, bandage lens that would cause itching and general photophobia. The Doctor removed my bandage lens after less than 48 hours and the same day I resumed my normal life. I was still sensitive to light but I could read screens without issues at all.
