Embodiment Construction

[0095] Figure 1-3 is a view showing a part of the human eye 20 . The eye 20 can be thought of conceptually as a fluid-filled ball with two chambers. The sclera 22 of the eye 20 surrounds a posterior chamber 24 filled with a viscous fluid known as the vitreous. The cornea 26 of the eye 20 surrounds an anterior chamber 30 filled with a fluid known as the aqueous humor. The cornea 26 meets the sclera 22 at a limbus 28 of the eye 20 . The lens 32 of the eye 20 is located between the anterior chamber 30 and the posterior chamber 24 . The lens 32 is held in place by a number of ciliary cords 34 .

[0096] When a person observes an object, he observes the object through the cornea, aqueous humor and lens of the eye. To be transparent, the cornea and lens may not include blood vessels. Therefore, no blood flows through the cornea and lens to provide nutrients to and remove waste from these tissues. Instead, these functions are carried out by the aqueous humor. The continuous ...

Abstract

An ocular implant (100) adapted to reside at least partially in a portion of Schlemm' s canal (38) of an eye (20). In some embodiments the implant has a body (104) extending in a curved volume whose longitudinal axis forms an arc of a circle, and a plurality of open areas and strut areas formed in the body (104), the open areas extending over more than 50% of a surface defining the curved volume, the strut areas surrounding the open areas, the body having a diameter of between 0.005 inches and 0.04 inches. The application also provides a method of treating glaucoma including the steps of supporting tissue forming Schlemm' s canal in an eye with an implant extending at least partially in the canal along an axial length within the canal; and contacting with the implant less than 50% of the tissue forming the canal along the axial length.
