I'd be very surprised if anyone onboard an aircraft had corneal damage from being shone on with l@sers, unless they were disoriented as a result and stuck something into their eye
It's a question of energy output and distance. Some people make "laser pointers" out of high-power industrial diodes scavenged from various sources - these are not your average "toy" pointers. I would not at all be surprised if they cause serious damage to the eyes of a helicopter pilot at close distance (and if you make it a single pilot, you have all the holes in the cheese lined up).
Even at longer distances, one could imagine various unfortunate scenarios.
