Abstract

Deep Anterior Lamellar Keratoplasty (DALK) is a corneal transplant procedure in which the patient’s central corneal epithelium and stroma is replaced with donor epithelium and stroma, retaining host Descemet’s membrane and endothelium. Surgical principles for achieving optimal visual results for DALK include the following: obtain clean and smooth surfaces for the graft-host interface; leave a posterior layer of uniform thickness; and achieve the deepest possible interface. The big-bubble technique most easily and safely accomplishes these objectives. The chapter explains in detail the surgical procedures of DALK (big-bubble) technique.
