Love4Flights,
Eyesight is key to being a pilot. That's the first criterior. Lasik, even though accepted by SIA, they are still very careful in their screening as even though after one year, your eyes are perfect, it is not proven that it will be such forever. That is why those that had gone through lasik need an optomologist clearance every year. However, SIA frowns upon people who have more than 500 degrees for pre-op. That's what it's set. (even the CAAS people advised that.) I don't know of any cases that have advanced yet. Anyone care to shed more light on this?
