Barosurgery, the Surgical Use of Air, as a Technique to Promote Adhesion Between Corneal Layers in Lamellar Keratoplasty

In this article, we describe the techniques for the safe use of air in bonding Descemet to stroma in corneal transplant surgery. Barosurgery, the surgical use of air, can help in both anterior and posterior lamellar grafts to secure good apposition of the corneal layers. We describe the management and the prevention of complications such as anterior and posterior pupillary block both during and after surgery. The concepts presented here will help the lamellar transplant surgeon feel comfortable in safely using air to manage the full spectrum of problems with donor adherence.
