From: Effect of Air Injection Depth on Big-bubble Formation in Lamellar Keratoplasty: an Ex Vivo Study
Transmission electron microscopic images for type I and II big bubbles (BB) created by the depth-sensing needle, respectively. Descemet’s membrane and the corneal endothelial layer were found with posterior stromal layer (A) or without posterior stromal layer (B) in types I and II BBs, respectively. The black solid scale bar represents 2 µm.
