Abstract
We describe a simple technique for inserting the donor corneal lenticule in Descemet's stripping automated endothelial keratoplasty. Unlike the standard insertion method, which requires folding the donor lenticule, this technique uses a modified intraocular lens (IOL) glide to guide the unfolded donor lenticule through the small incision with an intraocular forceps. This prevents significant endothelial trauma and surgical difficulties when the lenticule is unfolded. Additional endothelial protection is provided by an ophthalmic visco-surgical device on the IOL glide, which protects the donor endothelium from the corneal wound edge and prevents iris prolapse during insertion.
