I not sure lasik can do in NS or not.
If can, good to do it in NS.
lasik cannot. cos its under cosmetic surgery. and can be
corrected easily by wearing glasses.
and its really worth it to extract your wisdom tooth during
NS.
it would cost around $1200 outside, and depending on your job, the
mc might be disruptive. e.g. you are a student, den suay suay your
wisdom tooth got infected and need immediate extraction, and
somehow kena exam period.
or if you are earning daily pay, e.g. taxi driver. not being
able to work would have an impact on you etc.
