Abstract
A glaucoma aqueous humor drainage device and a glaucoma aqueous humor drainage method, wherein the opening and closing of a pressure valve is controlled by the change in the pressure in a cavity of the valve. When the pressure in the intraocular pressure exceeds 12 mmHg, the valve is opened, and a drainage tube connected behind the valve drains the aqueous humor to the ocular surface, reducing the patient's discomfort and dry eyes, effectively draining the aqueous humor and avoiding scarring caused by embedding the device via a conjunctival flap and operation failure caused by increase of intraocular pressure caused by generation of filtering blebs.
