    Pupil expander manages unique needs of small pupils

    Single-use device provides stability; simplifies ease of insertion and removal

    Take-home message: A pupil expansion device is flexible, yet stable and can easily be inserted and removed for cataract surgery procedures.

     

    Boston—A pupil expansion device (I-Ring Pupil Expander, Beaver-Visitec) is an innovative step in helping surgeons manage small pupils during cataract surgery, said Roberto Pineda, MD.

    “It’s an incredibly valuable device for many of our cataract surgery patients,” said Dr. Pineda, director, Refractive Surgery, Massachusetts Eye and Ear, Harvard Medical School, Boston. “I think it provides better stability than a lot of the current ring-like devices.

    “It’s very flexible and can be easily inserted into the eye through the same cataract incision, down to a 2.2-mm incision,” he added. “On average, the pupil is 6.4 to 6.5 mm with this device, and that provides adequate dilation for the vast majority of cases. Also, the device can be placed in the pupil margin a little more quickly than some of the other devices.”

    Testing it out

    Dr. Pineda was one of several surgeons invited to test prototypes of the ring and provide feedback. Although he was initially skeptical about how this new device would differ from others, he discovered features that help increase and maintain a larger pupil size and reduce the risk of complications during a procedure.
