Modified "Top-up sandwich" technique for the management of corneal perforations: A case report and a literature review.

ABSTRACT:

Purpose

We describe a modified technique for managing a peripheral, non-infected, corneal perforation using a "Sandwich" technique that combines posterior lamellar keratoplasty, an amniotic membrane patch and a Gundersen conjunctival flap.

Observations

A 75-year-old female patient presented with Sjogren's syndrome-related corneal perforation. A mini-Descemet stripping automated endothelial keratoplasty (DSAEK) graft (5 mm) was introduced into the anterior chamber and was mobilized to plug the perforation. Then, two amniotic membrane patches were stacked over the perforation and glued. Finally, the whole area was covered with a Gundersen conjunctival flap, mobilized from the inferior conjunctiva and secured in place using interrupted 10-0 nylon sutures. A step-by-step guide i
