Can Lasik be done for a third time? Can soft contacts be worn after having Lasik twice?

I'm 45 years old. I started wearing soft contacts at age 12 always with chronic dry eyes, had first lasik surgery at 27 and again at age 30. Everything is now fuzzy but really blurry after dusk. My eyes are still extremely dry and sometimes itchy and I'm always squinting and have to drive with the map light on in my vehicle after dark to help me focus a little. Can I comfortably wear soft contacts again or can the surgery be re-enhanced again with a third surgery?
