The most important task, IMO, of a GP is to protect the patient as much as possible from the deleterious effects of hospital and secondary care. Don't get me wrong -- there are many wonderful medical treatments these days, but all have potential harms associated and should be administered with the greatest possible care and only when absolutely necessary.
For a professional pilot to submit themelves to laser treatment on their eye for convenience sake when the treatment has at best a long downtime and at worst an uncertain outcome strikes me as silly.
Don't believe anyone who tells you a treatment has no side effects or is perfectly safe. Such a medical treatment has not been invented so far and will never be invented.
