1. A method for inserting an intraocular pressure relieving device into an eye, the eye comprising a cornea, a lens, sclera, conjunctiva, and corneal endothelium, the method comprising:
- determining a site for locating the pressure relieving device;
making a corneal incision in an area remote from the site for locating the pressure relieving device;
inserting a drill or laser into the corneal incision;
creating an opening or passage with the drill or laser;
extending the opening or passage into the sclera of the eye remote from the corneal incision;
forming a chamber or pocket at a terminal end of the opening or passage in the sclera;
removing excess sclera from the chamber or pocket;
deforming a pressure relieving device;
inserting the deformed pressure relieving device through the opening/passage and into the chamber or pocket; and
allowing the deformed pressure relieving device to return to its original form after inserting it in the chamber or pocket.

6. A method for relieving intraocular pressure in an eye, the eye comprising a cornea, corneal endothelium, conjuncitva, tenon, anterior chamber, sclera and trabecular meshwork, the method comprising:
-
determining a site for locating a pressure relieving device;
making a corneal incision in an area remote from the site for locating the pressure relieving device;
inserting a drill or laser into the corneal incision across an anterior chamber to the trabecular meshwork of the eye;
creating a passage with the drill or laser;
extending the passage into the sclera remote from the corneal incision;
forming a pocket at the end of the passage that is larger in at least one dimension than the passage;
removing excess sclera from the pocket;
deforming a pressure relieving device;
inserting the deformed pressure relieving device through the passage and into the pocket; and
allowing the deformed pressure relieving device to return to its original form once it is placed in the pocket.

7. A device for excising sclera in an eye to form a chamber for insertion of a device for relieving intraocular pressure comprising:
-
a blade carrying body;
at least one moveable cutting blade having a first or retracted position and a second or extended position wherein the at least one cutting blade extends beyond the body;
means for moving the at least one cutting blade from the first position to the second position, and back to the first position; and
means for moving the at least one cutting blade, while in the second position, around the body. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

23. A method for creating chambers consisting of:
-
creating a passageway;
inserting a device with guarded blade or blades;
retracting the guard;
applying power to the blades so that they expand and cut material to a size larger than the entry passageway;
redeploying the guard over the blade or blades; and
removing the device through the original passageway.

- 24. An implantable device for relieving aqueous pressure in an eye comprising a system of passageways, pores, or channels formed through the device and on its surface.
-
29. A method of inserting a deformable pressure relieving device into an eye comprising;
-
deforming the device;
inserting the device into a delivery device;
creating a passageway in the eye;
creating a chamber at a terminal end of the passageway;
inserting the delivery device through the passageway and into the chamber; and
ejecting the pressure relieving device from the delivery device and into the chamber. - View Dependent Claims (30, 31, 32)
