Big-bubble technique to bare Descemet's membrane in anterior lamellar keratoplasty

Abstract
Injected. In most cases, this forms a large air bubble between Descemet's membrane and the corneal stroma. After anterior lamellar keratectomy is performed, a small opening is made in the air bubble and the remaining stromal layers are lifted with an iris spatula, severed with a blade, and excised with scissors. This technique is faster, safer, and easier to perform than previous methods....
