imho you probably wouldn't feel it. When I had lasik, the surgeon sliced the top 1/8 of an inch off the front of my eye ball with a scalple(sp?) I didn't take any meds before, and even though he basically took a razor to my eye all I felt was pressure. When you get glass in your eye, what hurts is the glass touching the inside of the eye socket, not your eye.....
not only that, if its a clean cut, it should heal quickly. When the surgeon put the flap he cut back on my eye it healed almost right away......
