Sutureless, Posterior Lamellar Keratoplasty

Abstract

Sutureless, posterior lamellar keratoplasty may be an effective new surgical approach for managing corneal endothelial disorders.

Descemet membrane endothelial keratoplasty (DMEK) for Fuchs endothelial dystrophy: review of the first 50 consecutive cases

“…[1][2][3][4][5][6] These techniques have been popularised in the United States as 'deep lamellar endothelial keratoplasty' (DLEK), 7,8 and (femtosecond) Descemet stripping (automated) endothelial keratoplasty (DSEK/DSAEK/FS-DSEK). [9][10][11][12] In 1998, we also described a technique for selective transplantation of Descemet membrane through a self-sealing 3.5 mm clear corneal incision, 13,14 tentatively named Descemet membrane endothelial keratoplasty (DMEK).…”

“…The early forms of endothelial keratoplasty, that is, DLEK and DSEK/ DSAEK, may have shown that the visual outcome could compete with PK, whereas the most frequent long-term complications were minimised. [1][2][3][4][5][6][7][8][9][10][11] Endothelial keratoplasty shows little induced astigmatism because the recipient corneal surface is not compromised; suturerelated problems are eliminated as endothelial keratoplasty requires no (corneal) sutures; and wound healing-related complications are rare, because instead of a circular corneal wound, the procedure can be performed through a self-sealing limbal or scleral tunnel incision.…”

A method for true endothelial cell (Tencell) transplantation using a custom-made cannula for the treatment of endothelial cell failure

“…[1][2][3] However, the technique of DLEK is technically demanding. Additionally, it involves creating a stroma-to-stroma interface, which can reduce the final best-corrected visual acuity.…”

Descemet-Stripping Automated Endothelial Keratoplasty

“…P ioneered by Melles et al in 1997, [1][2][3][4] posterior lamellar keratoplasty (PLK) advanced the treatment of corneal endothelial dysfunction (Fuch and bullous keratopathy) by eliminating the numerous weaknesses of the standard procedure, penetrating keratoplasty (PKP). These flaws included prolonged visual recovery, induced irregular and regular astigmatism, and the long-term risk of traumatic wound rupture.…”
