Background: A corneal transplant, or graft, known as a "penetrating keratoplasty," replaces the whole thickness of the cornea. The inner layers of the cornea are transplanted during traditional posterior lamellar keratoplasty (LK) and the more recent “endothelial keratoplasty (EK) operations. Deep lamellar EK, Descemet's stripping (automated) EK (DSEK or DSAEK), Descemet's membrane EK, and Descemet's membrane automated EK” are examples of these procedures' variations. Objective: In order to compare “deep anterior lamellar keratoplasty (DALK)” with “penetrating keratoplasty (PK)” for the outcomes of “best spectacle-corrected visual acuity (BSCVA)”, refractive error, immunological graft rejection, and graft survival, it is necessary to evaluate the published literature on DALK. Methods and Materials: The Cochrane Library and PubMed databases were searched for peer-reviewed literature. The most current search was conducted in May 2009, and the searches were restricted to citations dating back to 1997. 1024 citations in English-language journals were found thanks to the searches. After reviewing the abstracts of these publications, 160 were chosen for likely clinical relevance, of which 53 were found to be pertinent to the assessment aim.
