Key Concepts The cannula “big bubble” (BB) technique and the bubble test lessen the possibility of deep anterior lamellar keratoplasty (DALK) intraoperative complications. If the air BB fails, the air-visco bubble (AVB) technique can be used. A manual dissection can…
Key Concepts Anterior lamella keratoplasty (ALK) techniques allow the surgeon to selectively dissect parts of the diseased corneal stroma while sparing the healthy remaining stroma and endothelium. The stromal dissection has to be deep (residual bed thickness <80 μm) and…
Key Concepts Anterior lamellar keratoplasty includes techniques whereby the diseased corneal stroma is partially or totally replaced by donor tissue, provided the endothelium is still healthy. Anterior lamellar keratoplasty induces a low immunologic insult. This allows for larger grafts without…
