Getting lasik in the military?

When can I obtain lasik in the military? All of my local recruiters have told me it would be after I'm assigned to my permanent duty station. Also they stated since that reason for me needing lasik is because of front-line duty (example: I'm in the 101st Airborne and glasses are a pain in the *** out in the field.) that I would be put at the top of the waiting list. However I am skeptical that a grunt would get priority over an officer, no matter where that officer is stationed. Thank you for reading.
