No big deal. Had both eyes done about 7 years ago.
It is wierd in a way, you are awake when they do it. You are
looking at the doctor then it gets black, that is because they
are working on the eye.
Mine was done about 6-8 months apart. Reason being if something goes wrong you still have one good eye.
The other weired thing is you are going to see daylight like you
never saw before. Everything is so bright!
Enjoy it
