Too thin for LASIK

Based solely on your corneal thickness and prescription, you would not be a good candidate for LASIK.  The amount of tissue that needs to be ablated with the laser to fully correct for your prescription will be too much and will leave your corneas too thin.

You may be a candidate for the Visian ICL procedure. Because of your thin cornea it may be safer to go with the ICL surgery.
