Abstract

Aspects of the present disclosure are directed to an ocular drainage device that includes a stability system. The stability system includes a plate, and can further include a material comprising collagen covering at least a portion of a top surface of the plate, and / or a viscoelastic substance covering at least a portion of the plate's top surface. The plate is formed of a flexible material and includes a tube retaining structure integrally formed therewith, wherein the tube retaining structure is configured to hold a tube that is at least partially surrounded by the tube retaining structure to the plate when the tube is moved. The tube retaining structure can include a low profile ridge, and / or a channel having an undercut or horseshoe shape. The plate has at least one plate channel, including a plate channel configured for carrying the tube. The plate can further include a reservoir.

Description

technical field [0001] The present invention generally relates to the field of ophthalmology. In particular, the present invention relates to implantable ocular devices, including ocular drainage devices. More particularly, the present invention relates to glaucoma drainage devices (hereinafter referred to as 'GDDs'), methods of manufacturing GDDs, and methods of implanting GDDs. Background technique [0002] Glaucoma, if left untreated, can lead to irreversible blindness. Sixty million people were diagnosed with glaucoma in 2010, and eight million of them developed blindness. Glaucoma occurs when the intraocular pressure (IOP) in the eye increases above normal levels due to a higher inflow than outflow of aqueous fluid. While drug therapy is effective, one problem is compliance since drug therapy often uses multiple drugs. For example, studies have shown that for patients undergoing drug therapy there is a 50% non-adherence within 6 months of drug therapy. Trabeculecto...
