Swimming, in general, is safest after 3-4 weeks of LASIK or a laser eye surgery where a ‘flap’ has been made. It is also best to always use swimming goggles in chlorinated pools to protect the eyes from allergies post swimming.
Many undergo LASIK or laser eye surgery during their vacation and time may be spent near a beach or a pool. It is alright to ‘wade’ in the water with swim eyewear, or if just ‘lounging’ by the pool, with sunglasses within a few days of the treatment.
