FACT: LASIK Has Been Approved for All Flight Activities
There is no reason to be concerned about flying after LASIK, as a passenger or as a pilot. Airplane air is dry, so it is helpful to bring artificial tears with you when you fly, especially during the first 6 months after surgery.
An extreme example of LASIK flap safety while flying may be found in the experience of a naval flight officer who ejected from his F/A-18F Super Hornet at 13 000 feet at a speed in excess of 400 miles per hour. His 7-year old LASIK flap was unharmed, and vision the next day was 20/15. 
Another study showed that 88% of pilots who land on aircraft carriers at night found their night vision to be better after LASIK with no glasses than they did with their glasses before surgery.

Title: Extreme LASIK flap stability

Précis: A 28-year-old male F/A-18F Super Hornet naval flight officer ejected from an aircraft at 13 000 feet at a speed in excess of 400 miles per hour 7 years after LASIK. His LASIK flap was unharmed, and vision the next day was 20/15.

Précis: Amongst 633 active-duty naval aviators who were treated with modern LASIK, 99.6% would recommend the treatment to others and 95% stated that LASIK had helped them be more effective at their job. Uncorrected vision was 20/20 for 98.3% of nearsighted and 95.7% of farsighted eyes by 3 months after surgery, and more than 1 in 3 gained at least 1 line of vision while just 0.4% (2 eyes) lost any vision. Night vision after LASIK was reported to better than pre-surgery with glasses by 88% amongst these pilots whose job requirements include landing on aircraft carriers at night.
