Retrospective safety study of the herrick lacrimal plug: a device used to occlude the lacrimal canaliculus.

Purpose: The purpose of this study was to evaluate the safety of the Herrick Lacrimal Plug (HLP) (Lacrimedics, Eastsound, WA) by reviewing medical records obtained from patients in whom the HLP was implanted.

Methods: A total of 228, primarily dry-eye, patients who had received one or more HLP implants at 19 centers during 1994 were included in the review; both centers and patients were randomly selected for inclusion. Medical records were examined for evidence of adverse events, which were characterized by presumed relationship to treatment, time of occurrence, severity, treatment required, and clinical outcome.
