The kebab technique uses a bipolar pencil to retrieve a dropped nucleus of the lens via a small incision.

Sci Rep 2021 Apr 12;11(1):7897. Epub 2021 Apr 12.

Division of Ophthalmology, Department of Visual Sciences, Nihon University School of Medicine, 30-1 Oyaguchi-Kamicho, Itabashi-ku, Tokyo, 173-8610, Japan.
