Hello dear A. Information provided by you is very less B.kindly provide the corneal thickness ...this is most important factor in deciding type of laser C. Yes..in old age you will need cataract surgery..and that is a very simple surgery with good results

You  can go for LASIK because your corneal thickness is around 500micron& 1D myopic correction leads to reduction by 35micron so still your thickness will be more than 300 micron which is on safe side,but you should know few fine print before going for LASIK.Even after LASIK you will need reading glasses  after40 yrs changing  every two years till cataract in old age.LASIK  does not cause any problem in cataract surgery provided you had uneventful LASIK

Bladeless LASIK or PRK is a better option as the number is on the higher side.. Yes.. preserve all your pre- LASIK data to enable a flawless cataract surgery in future.. no prob with that. Thanks
