Question on Lasik Surgery? It's relevant to my wedding

So, I am talking to my MOH (she lives in TX) on the phone last night and she was expressing how psyched she is about coming up for the wedding next week.
Well, she mentioned in the conversation that she got lasik surgery yesterday.

I am concerned b/c I remember when my dad had surgery b/c of his separated retina...he could travel in the airplane because of the pressure. When I told my MOH, she didn't inquire with the doctor because she did not think of it. She will find out today, but do any of you know if she can travel in an Airplane? I will be so upset because I really want her here.
