The majority of patients who have LASIK on a Friday are driving the next day and back to work on Monday. The only restrictions are to be a little extra careful with exceptional exercise(basketball, marathons, swimming,etc) for about a week or so. Your surgeon should give you a very thorough instruction list of "do's and don'ts" for the first one to two weeks.
LASIK patients are a very active group, so we don't hold you down very long. Air travel if fine after about two days, though sometimes the eyes can feel dry on the airplane, so we give extra tear drops to our travelers. I had PRK performed on myself in 1994. It was done on a late Thursday afternoon. I flew in an airplane on Friday and operated all day on Monday! So, I fit the profile of a very active Laser Vision Correction patient!
