SIENA, Italy — A new set of surgical instruments makes deep anterior lamellar keratoplasty with the big-bubble technique easier and safer, according to one surgeon speaking at the meeting of the Italian Society of Corneal Transplantation.
The new set, developed and produced by E. Janach, encompasses three instruments: an intrastromal pocket dissector, a 27-gauge air injection cannula and a disc-shaped spatula.
"The dissector creates a triangular pocket in which the tip of the cannula for inflating the air bubble is inserted. The cannula has a flat profile with an aperture in the inferior surface and is shaped with an anatomic curvature that perfectly fits corneal curvature. The spatula is used to separate Descemet's stromal adhesions," Luigi Fontana, MD, explained. "They will soon be produced as a single-use instrument set."
The big bubble is a delicate procedure that requires equally delicate instruments. Sterilization and repeated use might alter the quality and efficiency of the instruments.
"A single-use big-bubble set will guarantee the highest level of safety and performance," Dr. Fontana said.
