I, typically, recommend no swimming or excessive exertion for approximately one week after Lasik, PRK or Cataract surgery. Although this is likely to be overly cautious, it also gets the patient in the frame of mind to be somewhat more sedentary after surgery, and I have found this reduces the risk of injury to the eye. Examples of this would be cycling, boxing, basketball, swimming, etc. I do not restrict patients from variations in altitude, like we experience in an airplane, so traveling is fine. One has to remember, though, the air on an airplane is considerably drier than usual, so we will prepare you with extra rewetting drops if you have a trip planned. My advice is to use common sense after any surgery, including eye surgery. Take it easy for a week and things will be fine.
