(B) Cyanoacrylate glue applications techniques, (i) traditional technique: direct application of a drop of cyanoacrylate glue on a pre-dried ocular tissue, and (ii) patient eye treated with this technique; (iii) infant cannula technique: a small disc of a non-adhesive material is cut with a punch biopsy, an infant cannula (without needle) is used to pick up and hold the disc, a drop of glue is applied on the disc, and finally the glue is placed gently on the pre-dried ocular tissue, (iv) patient eye treated with this technique, (v) corneal tissue repaired with this technique.
