Core Tip
Core tip: Deep anterior lamellar keratoplasty (DALK) is recently used for treating corneal diseases not affecting the corneal endothelium. This makes it possible to use donor tissue with poor endothelium. Furthermore, DALK allows acellular corneal tissue to be used and long-term preservation techniques are being considered as a method for donor storage. The recent alterations may require eye banks and corneal surgeons to reassess their selection criteria to ensure donor grafts which are inappropriate for penetrating keratoplasty because of low endothelial cell count can be safely used for DALK.
