Technical Field
The present invention relates to an ocular disease implant device for regulating intraocular pressure, and more particularly to an ocular disease implant device which has a double structure capable of more effectively discharging aqueous humor of an ocular disease patient such as glaucoma and is composed of a substance that degrades in the eye over time.
Background
Glaucoma is a disease in which the pressure of the optic nerve or the blood supply is impaired due to the increase of intraocular pressure, and further, the function of the optic nerve is abnormal. Since the optic nerve is a nerve for transmitting light received by the eyes to the brain, it causes a visual field loss when abnormality occurs in the optic nerve and leads to a loss of vision at a later stage. The most important cause of early-field glaucoma is damage to the optic nerve due to increased intraocular pressure. Intraocular pressure is primarily dependent on aqueous humor (meaning water produced in the eye that serves to maintain the morphology of the eye and supply nutrients to the interior of the eye).
The method for treating glaucoma as described above includes a glaucoma filtration operation or the like in which an intraocular pressure-lowering drug is used in an eye drop form or orally administered, or a small hole is drilled in the iris with a laser beam to assist the circulation and drainage of aqueous humor of the eye, and when the above-described drug therapy and filtration operation fails or the intraocular pressure rises after the drug therapy and filtration operation is prevented, an insertion operation of an implant device can be performed in which the intraocular pressure is maintained at a constant level by adjusting the amount of aqueous humor in the eye.
The conventional implant devices that are surgically inserted into the eyeball as described above are mostly tubular devices made of silicone material having a certain diameter, and thus, since they are formed with a certain diameter, a certain amount of aqueous humor is continuously discharged regardless of the intraocular pressure value after insertion, and thus it is difficult to effectively adjust the intraocular pressure.
Further, in order to stably fix the implant device to the inside of the eye, a structure in which a projection is formed on the outer surface of the implant device and the implant device is manufactured in a reversed-l shape is adopted in korean laid-open patent publication No. 10-2017-0058811, but when the device is formed as described above, there is a possibility that an eyeball tissue is damaged during insertion, and a problem that aqueous humor cannot be effectively discharged due to the reversed-l shape.

Means for solving the problems

ADVANTAGEOUS EFFECTS OF INVENTION
By applying the implant device for ocular diseases according to one embodiment of the present invention, it is possible to degrade the inner tube of the device with the lapse of time, thereby regulating the discharge amount of aqueous humor generated in the anterior chamber of the eyeball and thereby effectively treating ocular diseases.
In addition, by adopting a configuration in which a part of the tube is expanded according to inflow of aqueous humor, it is possible to adjust the internal pressure of the tube when the aqueous humor flows in and to effectively discharge the aqueous humor, and also to ensure the stability of the device because it can be fixed to the inside of the eye and does not move.
