Ocular collar stent for treating narrowing of the irideocorneal angle
First Claim
1. An annular ocular stent for insertion in an irideocorneal angle of an anterior chamber of an eye, the stent comprising:
- a continuous annular central portion;
an anterior portion protruding in an anterior direction from the central portion and being configured to provide variable contact around a circumference of the stent with a surface of a transition zone between a trabecular meshwork and a corneal endothelium of the eye; and
a posterior portion extending in a posterior direction from the central portion, the posterior portion being configured to contact a portion of a peripheral iris of the eye,wherein the posterior portion comprises a plurality of posterior supports extending radially along a posterior surface of the central portion from an inner radial edge of the central portion toward an outer radial edge of the central portion.

Abstract
An ocular stent for insertion in an anterior chamber of an eye is provided. The stent facilitates the restoration of the structure of an irideocorneal angle of the anterior chamber for treating structural changes from ocular aging. The stent includes: a continuous annular central portion; an anterior portion protruding in an anterior direction from the central portion and being configured to provide variable contact around a circumference of the stent with a surface of a transition zone between a trabecular meshwork and a corneal endothelium of the eye; and a posterior portion extending in a posterior direction from the central portion, the posterior portion being configured to contact a portion of a peripheral iris of the eye. A method for stabilizing the irideocorneal angle of the anterior chamber using a stent is also disclosed herein.

15. An annular ocular stent for insertion in an irideocorneal angle of an anterior chamber of an eye, the stent comprising:
-
a continuous annular body defining a rounded anterior surface and a posterior surface; a plurality of anterior protrusions integrally formed with and extending from the anterior surface, the anterior protrusions being configured to contact portions of a surface of a transition zone between a trabecular meshwork and a corneal endothelium of the eye to provide variable contact therewith about a circumference of the stent; and a plurality of posterior supports integrally formed with and protruding from the posterior surface of the body and extending radially along the posterior surface thereof from an inner radial edge of the body toward an outer radial edge thereof, the supports being configured to contact a peripheral iris of the eye. - View Dependent Claims (16, 17)

18. A method of stabilizing an irideocorneal angle of an anterior chamber of an eye, the method comprising:
-
providing an annular ocular stent comprising a continuous annular central portion, an anterior portion protruding in an anterior direction from the central portion and being configured to provide variable contact around a circumference of the stent with a surface of a transition zone between a trabecular meshwork and a corneal endothelium of the eye, and a posterior portion extending in a posterior direction from the central portion, the posterior portion being configured to contact a portion of a peripheral iris of the eye, wherein the posterior portion comprises a plurality of posterior supports extending radially along a posterior surface of the central portion from an inner radial edge of the central portion toward an outer radial edge of the central portion; inserting the stent into the anterior chamber of the eye, such that the stent is in contact with soft tissue of the anterior chamber; and stabilizing the irideocorneal angle of the anterior chamber of the eye by simultaneously applying pressure in an anterior direction with the anterior portion of the stent to portions of the surface of the transition zone between the trabecular meshwork and the corneal endothelium of the eye and in a posterior direction with the plurality of posterior supports of the posterior portion of the stent to the peripheral iris of the eye. - View Dependent Claims (19)
