Abstract: Corneal endothelial dysfunction can severely affect visual acuity.In order to deal with this morbidity, ophthalmologists used to perform penetrating keratoplasty, in which the complications, such as postoperative astigmatism and graft rejection,led to poor visual recovery.If only the Descemet's membrane and endothelium is transplanted, the corneal injury of recipients caused by surgeries would be reduced and better visual acuity recovery might be guaranteed.In the past few years, the advantages of sutureleas deep lamellar endothelial keratoplasty have been brought to the attention by more and more ophthalmologists worldwide.However, the challenging techniques of performing DLEK limits its chnical application.Other kind of, DSEK, by stripping Descemet's membrane and endothelium from the recipient cornea, has produced excellent outcomes.This article outlined and analysed surgery techniques, clinical results and complications of DSEK.
