title: Coring: a potential problem in eye surgery.
abstract: Any needle passing through a rubber stopper can aspirate a core of rubber. This rubber may then be injected into the eye or into the retrobulbar or peribulbar space. Aspirates from a number of syringes were spun down in a centrifuge and examined for microscopic particles. All specimens contained microscopic particles even from half-used bottles of Xylocaine.
