Abstract
The present invention generally relates to the reduction of intraocular pressure, and in particular, to methods for treating glaucoma by insertion of an intraocular shunt in the eye such that it forms a drainage pathway between the anterior chamber and the intra-Tenon's space.
Claims24
A method of deploying an intraocular shunt into an eye having an anterior chamber, a sclera, and a Tenon's capsule, the method comprising the steps of:
- advancing a hollow shaft through the anterior chamber, the hollow shaft (a) having a beveled tip at a distal end of the hollow shaft and (b) holding the intraocular shunt with a proximal end of the shunt within the hollow shaft and a distal end of the shunt positioned closer to the distal end of the hollow shaft than is the proximal end of the shunt;
- penetrating the sclera with the hollow shaft;
- orienting a beveled surface of the beveled tip such that the beveled surface faces toward the Tenon's capsule when the beveled tip passes out of the sclera;
- positioning the distal end of the shunt in a space between the sclera and the Tenon's capsule;
- and
- positioning the proximal end of the shunt in the anterior chamber.

- advancing the hollow shaft into the sclera;
- orienting a beveled surface of the beveled tip such that the beveled surface faces away from the sclera when the beveled tip passes out of the sclera;
- advancing at least a portion of the shunt from the hollow shaft such that the distal end of the shunt resides in a space between the sclera and the Tenon's capsule;
- with the proximal end of the shunt in the anterior chamber, retracting the hollow shaft from the shunt.
