An aqueous humor drainage device with an adjustable tube diameter that is configured to be inserted into an eyeball to drain aqueous humor discharged from the eyeball to an outside, the aqueous humor drainage device comprising:
- an annular outer tube part having a first predetermined thickness and having a hollow inside;
- and
- an annular inner tube part coupled to an inner surface of the annular outer tube part and having a second predetermined thickness, the annular inner tube part including a hole therein, the hole extending along an axial direction of the annular inner tube part to be open at two opposite ends of the annular inner tube part, the annular inner tube part further including therein a plurality of porous portions, each pore in the porous portion extending along the axial direction of the annular inner tube part, each porous portion being open at the two opposite ends of the annular inner tube part, the plurality of porous portions surrounding the hole when viewed from a cross-section of the annular inner tube part perpendicular to the axial direction of the annular inner tube part,
- wherein the annular inner tube part includes a biodegradable material, and
- wherein a diameter of the hole is greater than a diameter of each porous portion.
An aqueous humor drainage device with an adjustable tube diameter that is configured to be inserted into an eyeball to drain aqueous humor discharged from the eyeball to an outside, the aqueous humor drainage device comprising:
- a polyhedral outer tube part having a first predetermined thickness and having a hollow inside;
- a polyhedral inner tube part coupled to an inner surface of the polyhedral outer tube part and having a second predetermined thickness, the polyhedral inner tube part including a hole therein, the hole extending along an axial direction of the polyhedral inner tube part to be open at two opposite ends of the polyhedral inner tube part, the polyhedral inner tube part further including therein a plurality of porous portions, each pore in the porous portion extending along the axial direction of the polyhedral inner tube part, each porous portion being open at the two opposite ends of the polyhedral inner tube part, the plurality of porous portions surrounding the hole when viewed from a cross-section of the polyhedral inner tube part perpendicular to the axial direction of the polyhedral inner tube part,
- wherein the polyhedral inner tube part includes a biodegradable material, and
- wherein a diameter of the hole is greater than a diameter of each porous portion,
- wherein the aqueous humor drainage device is configured to penetrate conjunctiva to be inserted into an anterior chamber to drain aqueous humor to outside.
