Title:
NOVEL GLAUCOMA DRAINAGE DEVICE FOR CONTROLLING INTRAOCULAR PRESSURE
Document Type and Number:
WIPO Patent Application WO/2022/139081
Kind Code:
A1
Abstract:
Glaucoma is a kind of eye diseases caused by an increase of intraocular pressure (IOP). An increase in intraocular pressure damages the appearance and function of the optic nerve and, when lasting, results in vision loss. However, conventional glaucoma drainage devices implanted to control a pressure have difficulty in effectively controlling the intraocular pressure because once the devices are inserted, a certain amount of aqueous humor is continuously discharged regardless of how much the intraocular pressure is. The present invention was designed to solve the above problems and relates to a novel glaucoma drainage device for controlling intraocular pressure. The glaucoma drainage device of the present invention is a dual glaucoma drainage device containing a tube made of a shape memory polymer therein and can control low and high intraocular pressures simultaneously, exhibiting an excellent function of maintaining the intraocular pressure within a clinically acceptable range.
