title: External refinement of the donor lenticule position during descemet's stripping and automated endothelial keratoplasty.
abstract: The authors describe a technique to facilitate the centration of the donor lenticule during Descemet's stripping and automated endothelial keratoplasty. The donor corneal lenticule is unfolded and grossly centered in the anterior chamber using a barbed 30-gauge needle on a 3-cc air syringe or a reverse Sinsky hook. Fine adjustments to center the lenticule can be achieved by applying external pressure to the cornea with a laser in-situ keratomileusis flap roller. This simple technique provides a mechanism for simultaneously removing interface fluid and allows the surgeon to center the donor corneal lenticule without further risk of direct mechanical trauma to the donor endothelium.
