Benefits of technology

The patent describes a method of treating glaucoma by using an implant that is placed in the eye to support tissue that forms a canal. The implant is designed to increase the flow of fluid between the eye's chamber and the canal, which can help to lower pressure in the eye and slow the progression of glaucoma. The implant has open areas and spine areas along its length, with the spine areas partially defining the channel where fluid flows. The supporting step involves orienting the openings of the implant towards a specific part of the eye (the trabecular mesh portion of the canal). Overall, this method offers a new and effective way to treat glaucoma.

Problems solved by technology

Researchers have theorized prolonged exposure to high intraocular pressure causes damage to the optic nerve that transmits sensory information from the eye to the brain.
This damage to the optic nerve results in loss of peripheral vision.
As glaucoma progresses, more and more of the visual field is lost until the patient is completely blind.

Embodiment Construction

[0083]FIG. 1 is a stylized perspective view depicting a portion of a human eye 20. Eye 20 can be conceptualized as a fluid filled ball having two chambers. Sclera 22 of eye 20 surrounds a posterior chamber 24 filled with a viscous fluid known as vitreous humor. Cornea 26 of eye 20 encloses an anterior chamber 30 that is filled with a fluid know as aqueous humor. The cornea 26 meets the sclera 22 at a limbus 28 of eye 20. A lens 32 of eye 20 is located between anterior chamber 30 and posterior chamber 24. Lens 32 is held in place by a number of ciliary zonules 34.

[0084]Whenever a person views an object, he or she is viewing that object through the cornea, the aqueous humor, and the lens of the eye. In order to be transparent, the cornea and the lens can include no blood vessels. Accordingly, no blood flows through the cornea and the lens to provide nutrition to these tissues and to remove wastes from these tissues. Instead, these functions are performed by the aqueous humor. A contin...

Abstract

An ocular implant having an inlet portion and a Schlemm's canal portion distal to the inlet portion, the inlet portion being disposed at a proximal end of the implant and sized and configured to be placed within an anterior chamber of a human eye, the Schlemm's canal portion being arranged and configured to be disposed within Schlemm's canal of the eye when the inlet portion is disposed in the anterior chamber.
