Does cross-linking required in correction with smile in high myopia?

I am 26 years old. I have nearsightedness since I was 10. Currently I have high myopia with astigmatism in left eye (R -8.75 L -8.25 astigmatism -1.5). 1.5 year ago my vision was R -7.25 L -7.75 astigmatism -0.5. I suppose this progression is due to inappropriate glasses that I am wearing ( lenses are -6.5 for both eyes). Cornea thickness is 566-574. I am planning to do laser correction. After the check-up at the eye clinic I was told that I can do any type of laser correction. My questions are:
1. Is my myopia still progressing? If yes, is laser correction allowed?
2. Can the progression in my myopia be due to inappropriate glasses and will it stop after laser correction?
3. Which type of laser correction is suggested in high myopia?
4. Does cross linking required in high myopia an will it help to reduce the risk of regression?

1. Yes your myopia is still progressing.  You also need a cornea topography to rule out keratoconus
2.  Not glasses RX,  yes could progress after refractive surgery
3.   None is 100% successful and you will need to discuss with your surgeon.
4. Cross linking is used to treat keratoconus (see #1)  If you have K-conus you should not have corneal refractive surgery
