I had two done in LOS, a month apart, they said, in case of a problem. No restrictions on sleeping, except wearing eye patch in case you rub or poke your eye when sleeping.
Do not let water in your eye when showering, and no swimming because of the chlorine.
Put the drops in your eye religiously as instructed, I saw folk who obviously didn't.
All the rest of the don't do this and do that, is more aligned to retina repair, I have had two of those done, much more complicated..🤕
