DALK with Big-Bubble Technique
DALK with Manual Dissection
By Francis W. Price Jr., MD
Cornea/External Disease
In this case, Dr. Francis Price performs a deep anterior lamellar keratoplasty (DALK) using the big-bubble technique. When Descemet's membrane remains adherent and no bubble can be formed, the surgeon converts to manual dissection of the stroma. The donor and recipient tissues are previously incised with femtosecond laser in a zigzag pattern that provides a secure, interlocking interface between the surfaces.
