i have spoke to at least 2 SQ pilots who know of crew with lasik done. I think there is a stabilisation period required between the time the op was done to the medical. I'm not sure if one year is sufficient but more research is needed.
A question to ask yourself is, would you be devastated is you were subsequently rejected after lasik. If you are able to accept that possibility then I think it is worth a go. After all (discounting the risks involved) you'd have improved vision, minus the pesky contacts/specs
