Self-sealing technique closes corneal incisions without sutures, glue or hydration

WAIKOLOA, Hawaii — A new technique for the closure of corneal incisions uses a valve mechanism of shelved incision, according to a speaker here.
“The idea is that the interior incision is closed up against the exterior incision and the pressure inside the eye keeps the wound self-sealing,” Ayman Naseri, MD, told colleagues at Hawaiian Eye.

First, the surgeon displaces the interface fluid using a common “squeegee” type of technique, Naseri said.
“Essentially, you are pressing down so the two leaflets displace any interface fluid,” he said. Second, the surgeon presses on the opposite limbus.
“The idea there is to create a vector force to try to shut the door, to get the interior leaflet to close against the exterior one,” he said.
Third, the surgeon slowly fills the anterior chamber through the paracentesis.
“It’s important to go through the para at this point, because we don’t want to open the valve that we’re trying to close. And, if you overfill, if you put too much fluid in, the fluid’s going to open the wound itself,” Naseri said.
Finally, the surgeon checks for a leak, which is an application for intraoperative OCT, which can confirm that the architecture is self-sealing.
“We’re starting to see literature on the use of intraoperative OCT for cataract surgeons,” he said. “And, I think we’re going to see more and more innovation as we learn more about the incisions we use in cataract surgery.”– by Patricia Nale, ELS
