Lasek with mitomycin c, Lasek with vitamin c, Lasik or Smile?

for higher prescription (-7.5 and -8.75) there is a risk of corneal scarring and haze with lasek and to mitigate against this Mitomycin C is used So with this added complication is the higher risk having flaps with lasik or havjng lasek with mmc kn long term? OR if lasem and no mmc maybe with vitamin c will haze and scar riskbe high ? Is haze lonv term with lasek? or smile without wavefront
