NEW YORK — The I-Ring pupil expander may consistently manage small pupils using a “backflip” technique, according to a speaker here.
At OSN New York 2015, Kenneth R. Kenyon, MD, presented the advantages of the pupil expander, a device that he and colleagues at Beaver-Visitec devised 2 years ago.
“I recommend this simple device. It’s kind of a next-gen strategy that has safety, consistency and reliability on its side,” he said.
The device is a single-use polyurethane ring with safe positioning holes that are isolated from the channel, living hinges to facilitate its insertion and removal, as well as channels that go all around the ring to support the pupillary margin for 360°.
The ring is injected into the anterior chamber, and a Sinskey hook is utilized to engage opposing lobes before it disengages the ring. Then the inserter is used to remove the ring back from where it came.
“The indicated polyurethane material is not too hard, not too soft. It’s just right and really supports the iris as well as enlarging the pupil. It hangs in there very well during all phases of the procedure, including IOL manipulation,” Kenyon said.
In his current technique, Kenyon uses a backflip technique to simply grasp the hinge points rather than disengage the ring.
The device received FDA class 1 exemption 6 months ago and CE mark approval 3 months ago. – by Kristie L. Kahl
