From: A novel sandwich technique of minimally invasive surgery for corneal perforation
Diagram showing the dissection and insertion of the cornea during the sandwich method. (a) The cornea graft with a 120 mm thickness is made and dissected using the corneal lenticules obtained from the small incision lenticule extraction (SMILE) donor. (b) A corneal lamellar separator creates the intrastromal pocket on the receptor cornea perforation area. (c) The dissected donor cornea is rolled and inserted into the intrastromal pocket. (d) The graft is ironed out and adjusted until it covers the center of the perforation region.
