Abstract: Intraocular stents are provided. An intraocular stent (20) includes a piercing end (40) for penetration into portions of the eye without requiring a surgical incision by a separate cutting device. A first retention member (50) stabilizes the intraocular stent (20) against the anterior wall of the canal of Schlemm. A second retention member (60) stabilizes the intraocular stent within the trabecular meshwork. A fluid inlet end (72) is configured to be disposed within the anterior chamber. In use. aqueous humor fluid flows into the fluid inlet end (72) through a central lumen (70) and/or drainage tubes (80) and out into the canal of Schlemm. Stack configurations of intraocular stents and insertion devices are also provided.
