Abstract: A method of reducing the risk of macular degeneration is provided. The method includes inserting an intraocular collar stent into a portion of a mammalian eye, such that the stent is in contact with soft tissue of the anterior chamber. When inserted in the eye, the stent applies pressure to a surface centered on a transition zone, between an anterior limit of a trabecular meshwork and a posterior limit of a corneal endothelium of the eye, to a surface of the peripheral iris of the eye, and in circumferentially expanding direction to the irideocorneal angle. The pressure is applied continually. The method also includes creating an environment of a reduced negative pressure state within the retina as a result of the application of the pressure; and, while the reduced negative pressure state is present, permitting drusen precursors formed by extracellular material to flow through the eye for removal by vasculature of the eye.

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 an annular body sized to fit in the irideocorneal angle of the eye. The body includes: an anterior portion configured to contact a surface of a transition zone between a trabecular meshwork and a corneal endothelium of the eye; a posterior portion configured to contact a peripheral iris of the eye; and a central portion connecting the anterior portion and the posterior portion of the body. A method for stabilizing the iredeocorneal angle of the anterior chamber using a stent is also disclosed herein.
