  • Publication number: 20250099296
    Abstract: An eye disease implant device for adjusting intraocular pressure may comprise: a tube body, one end of which is inserted into the anterior chamber of an eyeball and the other end of which is inserted into the conjunctival tissue or tenon tissue of the eyeball, the tube body including a hollow channel and being configured to discharge aqueous humor, produced in the anterior chamber of the eyeball, to the conjunctival tissue or tenon tissue via the hollow channel; and a wick which is configured to be inserted into the hollow channel of the tube body in order to adjust the formation pressure in the anterior chamber through the tube body. In the eye disease implant device, each part, such as the inner diameter of the tube and the diameter of the wick inserted into the tube, is designed such that the optimal formation pressure in the anterior chamber of the eyeball is achieved when lowering the intraocular pressure through the tube inserted into the anterior chamber.

  • Patent number: 11793673
    Abstract: The present invention relates to an implant device for an eye disease for adjusting intraocular pressure. An implant device for an eye disease for adjusting the intraocular pressure according to an embodiment of the present invention comprises: a first tube into which the aqueous humor flows so as to adjust the intraocular pressure; and a second tube formed inside the first tube. The second tube is made of a biodegradable material configured to be degraded inside the eye over a predetermined period of time after being inserted into the eye. The first tube and the second tube may be divided into a first area and a second area according to the distance from the anterior chamber of the eyeball. The second area of the first tube and the second tube may have such a structure that the diameter thereof is larger than that of the first area of the first tube and the second tube, and the same can expand as the aqueous humor flows in.

  • Publication number: 20220395396
    Abstract: The present disclosure relates to an eye disease implant device, and an eye disease implant device according to an embodiment of the present disclosure includes a tube including a hollow portion through which aqueous humor is drained, wherein one or more wings extending in a direction different from a longitudinal direction of the tube are formed on a portion of an outer surface of the tube. Also, the eye disease implant device may further include a body including a receiving space into which an end of the tube is inserted. In this case, the end of the tube may be inserted into the receiving space to be coupled to the body, or detached from the receiving space to be separated from the body.

  • Publication number: 20220133953
    Abstract: An implant for eye disease for controlling intraocular pressure, the implant including a coating layer formed on the outside of an implant substrate. Specifically, the present invention relates to an implant that may suppress a foreign body reaction from occurring around the implant, because the implant includes a coating layer, which is formed on the outside of an implant substrate and is a cured product of a polymer of a composition containing an acrylate-based monomer and a (meth)acryloyloxyethyl phosphorylcholine monomer.
