Do I have Ptosis ? Lasik first or Ptosis surgery first? (photos)

I did a non-incisional double eyelid surgery 7 years ago but the double eyelids have now disappeared. I am now wondering whether I have ptosis as I am in early 40s now. If yes, is it mild or moderate as I am considering a surgery to improve the look. I am also looking at lasik as I have quite high degree of above 800 . Should I go for the ptosis surgery first or lasik first?
