Endothelial keratoplasty (EK) has gradually replaced penetrating keratoplasty (PKP) and has become the main method for the treatment of endothelial dysfunction in developed countries in recent years. EK is safe and effective and can achieve good postoperative vision. The surgical techniques and postoperative effects have been improved continuously along with the development of microsurgical technology and surgical instruments. The EK surgeries mainly include Descemet stripping endothelial keratoplasty (DSEK), Descemet stripping automated endothelial keratoplasty (DSAEK), Descemet membrane endothelial keratoplasty (DMEK) and ultra-thin Descemet stripping automated endothelial keratoplasty (UT-DSAEK), which have different characteristics and advantages compared with PKP...

Corneal dystrophies are categorized according to the International Committee for Classification of Corneal Dystrophies (IC3D) classification, and their treatment depends on the affected structures and layer of the cornea. Therefore, estimating the depth and extent of the morphological changes due to the specific dystrophy is crucial when deciding between different treatment options. Besides superficial laser treatments and penetrating keratoplasty, minimal invasive lamellar keratoplasties such as Descemet membrane endothelial keratoplasty), deep anterior lamellar keratoplasty, or Descemet stripping automated keratoplasty have become increasingly popular to exchange the specific opaque layers in dystrophic eyes...

PURPOSE: Corneal endothelial dysfunction is a major indication for corneal graft surgery worldwide, and although surgical intervention through a range of posterior lamellar surgeries has proven to be hugely beneficial, challenges remain. This is especially so where the anterior chamber is relatively shallow, as is often the case in the Asian population, though not exclusively so. In this study, we introduce a new insertion device to deliver endothelial graft tissue for Descemet stripping automated endothelial keratoplasty (DSAEK)...

Descemet membrane endothelial keratoplasty (DMEK) has evolved into a routine surgical procedure for posterior lamellar keratoplasty. After its introduction more than 10 years ago, several modifications in grafting technique and postoperative treatment regimen helped to improve its safety and reproducibility. Although DMEK offers faster and better improvements in visual acuity, as well as less graft rejections when compared to Descemet's stripping (automated) endothelial keratoplasty (DS[A]EK), difficulties when implementing this technique hamper the widespread use in many areas...

BACKGROUND: Descemet's membrane endothelial keratoplasty (DMEK) involves removal of the recipient's Descemet membrane (DM) prior to transplanting the donor's DM. When using balanced salt solution (BSS) or ophthalmic viscosurgical devices (OVDs), visualization of the host's DM during its stripping may be inadequate and may result in Descemet remnants and could lead to sub-optimal surgical results. Previous articles described excellent visualization when utilizing air injection but this requires repeated air injection into the anterior chamber (AC)...

Endothelial keratoplasty is at present the gold standard for surgical treatment of corneal endothelial pathologies not associated with significant corneal scar. Tremendous progress has been made in recent years in improving the technology of endothelial keratoplasty techniques, such as descemet stripping automated endothelial keratoplasty (DSAEK) and descemet membrane endothelial keratoplasty. In this review, we discuss the current techniques and outcomes of DSAEK.
