It sounds like you did not damage the flap when you rubbed your eye since you are not experiencing pain or vision loss. Continue using your preservative free artificial tears every few hours. To be safe, I would recommend that you see your eye doctor so they can take a look at your eyes.
you must be seen by your MD to make sure you did not move or dislodge or wrinkle the flap, in which case it must be put back and hopefully not sutured in place
this is yet another advantage of LASEK, as there is no flap, so you can rub all you want, the flap isn't going to move bc you never got any flap cut into your cornea to begin with
If the eye does not hurt and if your vision is the same, then you did not do any harm by rubbing the eye. It is best not to rub the eye, so maybe wear the goggles for a few nights more to prevent this from happening again.
