Lacrimal implant detection

摘要

This document discusses, among other things, an apparatus comprising a lacrimal implant insertable at least partially into a lacrimal punctum. The lacrimal implant comprises an implant core, and an implant body. The implant body includes a cavity sized and shaped to receive the implant core. At least one of the implant core and the implant cavity includes a detection device configured to allow automatic detection of the lacrimal implant with a separate detector device.

主权项

1. A lacrimal implant comprising:
a punctal plug insertable at least partially into a lacrimal punctum, the punctal plug comprising: an implant core comprising a matrix; a sheath body partially surrounding the implant core; a plug body, wherein the plug body includes a cavity sized and shaped to receive the implant core, the implant core disposed within the cavity, and a contrast agent configured to allow detection of the punctal plug with a separate detector device, wherein the contrast agent is present in at least one of the implant core and the plug body and configured to optically distinguish the lacrimal implant from a region of an eye.
