Not at all like infiltrating keratoplasty, DALK holds the back layers of the cornea, the Descemet's film and endothelium layer, set up and it is utilized as the other option to PK when these back layers of the cornea are solid. The surgery itself is completed much the same as PK, yet simply less contributor cornea is utilized.
