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.
