Intralamellar autopatch with lamellar keratoplasty for paracentral corneal perforations

Abstract

Purpose. To report a new technique of tectonic intralamellar autopatch with lamellar keratoplasty (LK) for paracentral corneal perforations. Methods. A partial thickness lamellar dissection of the host was undertaken to remove the superficial epithelium and the anterior stroma. A second lamellar dissection began at the periphery to approximately 1 mm away from the perforation to fashion a hinge. The hinged autolamellar flap was reflected over the perforation and sutured to the host with interrupted sutures. Finally, the autolamellar patch graft was supported by a lamellar graft, which was secured in place with 16 interrupted sutures. This technique was undertaken in 4 eyes with paracentral p..
