Abstract
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.
Claims46
A lacrimal implant for insertion into a lacrimal canaliculus of a patient comprising:
- a therapeutic agent and a contrast agent admixed with biocompatible material comprising a hydrogel polymer wherein the contrast agent is configured to optically distinguish the lacrimal implant from a region of an eye and wherein a release rate of the therapeutic agent and contrast agent are different.
A lacrimal implant for insertion into a lacrimal canaliculus of a patient comprising:
- a therapeutic agent and a contrast agent admixed with a biodegradable material comprising a hydrogel polymer wherein the contrast agent is configured to optically distinguish the lacrimal implant from a region of an eye and wherein a release rate of the therapeutic agent and contrast agent are different.
A lacrimal implant for insertion into a lacrimal canaliculus of a patient comprising:
- a therapeutic agent and a contrast agent admixed with a biodegradable hydrogel polymer wherein the contrast agent comprises a color material, a pigment, a luminescent material, or a dye, and wherein a release rate of the therapeutic agent and contrast agent are different.
A lacrimal implant for insertion into a lacrimal canaliculus of a patient comprising:
- a therapeutic agent, a detection agent and hydrogel polymers that form a hydrogel matrix with the therapeutic agent and detection agent dispersed through the hydrogel matrix, wherein the shape of the lacrimal implant consists of a constant diameter cylinder, and wherein a release rate of the therapeutic agent and detection agent are different.
A lacrimal implant for insertion into a lacrimal canaliculus of a patient comprising:
- a therapeutic agent, fluorescein and hydrogel polymers that form a hydrogel matrix with the therapeutic agent and fluorescein dispersed through the hydrogel matrix, wherein the shape of the lacrimal implant consists of a constant diameter cylinder, and wherein a release rate of the therapeutic agent and the fluorescein are different.
