Maybe I don't fully understand Lasik but I thought they were effectively making a corrective lens on the front of your eye..? In that case I would be concerned that they have corrected for your eyes WITH Diabetes. Now if your vision changes as the D comes under control you may end up needing glasses again. I certainly needed a different lens prescription after my D was controlled.
I'd also be concerned that the Lasik clinic did not test for Diabetes... not only can it affect your vision but it can also lead to higher risks of infection and longer healing times.
That said, I truly hope everything works out well for you
