No, when I realized the pupil would be very weak, I turned the piece over and applied a drop to the pupil, after cutting it. When I looked at the rest of the eye I applied the superglue, just on that area, before I cut it. I had to use fingernail polish remover to the paper around the pupil in order to get the pattern off the pupil without breaking it. I added the backer, in part, to strengthen these delicate areas.
