1. A method of placing an ocular device into the eye, comprising:
- providing a fluid drainage tube having a longitudinal, internal lumen, a first end and a second end;
forming a self-sealing incision in the cornea into the anterior chamber of the eye;
introducing the first end and second end of the fluid drainage tube through the self-sealing incision and into the anterior chamber;
separating at least a portion of the ciliary body from at least a portion of the sclera from within the anterior chamber so as to place the fluid drainage tube such that when implanted into the eye the first end of the drainage tube communicates with the suprachoroidal space, the second end of the fluid drainage tube is in the anterior chamber, and the internal lumen provides a pathway for aqueous humor to flow through the fluid drainage tube from the anterior chamber to the suprachoroidal space, so as to provide aqueous pressure regulation.

Abstract
This invention comprises a flexible ocular device for implantation into the eye formed of a biocompatible elastomeric material, foldable to a diameter of 1.5 mm or less, comprising a fluid drainage tube having at one end a foldable plate adapted to locate the device on the inner surface of the sclera in a suprachoroidal space formed by cyclodialysis, said drainage tube opening onto the disc at one end and opening to the anterior chamber when implanted into the eye at its other end, so as to provide aqueous pressure regulation. Also provided are methods for the treatment of glaucoma utilizing the flexible ocular device, and an ocular pressure spike shunt.

21. A method of treating an eye, comprising:
-
providing a fluid drainage tube having a longitudinal, internal lumen through which fluid can flow; forming an opening in the cornea to provide access to the anterior chamber of the eye; inserting the entire fluid drainage tube through the opening into the anterior chamber; accessing the sclera and the ciliary body of the eye from within the anterior chamber; and separating at least a portion of the sclera from at least a portion of the ciliary body and implanting the fluid drainage tube in the eye from within the anterior chamber such that the internal lumen provides a direct flow pathway from the anterior chamber to the suprachoroidal space of the eye. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 41, 42, 43, 44, 45, 46)
