  • Patent number: 6375642
    Abstract: A method for improving a drainage of aqueous humor in an eye of a living being and a device for maintaining the drainage of aqueous humor are described, wherein a first incision is made in a lamellar section of the sclera to form a first scleral flap which is then folded upwards in the direction of the cornea, thereby creating a recess in the sclera. A second scleral flap is formed by incising a second lamellar section in the area of the recess and lifted upwardly in the direction of the first sclera flap, thereby creating a second recess and exposing a portion of the Schlemm's canal for permitting injection of a highly viscous medium. At least one support element is implanted in the lumen of the Schlemm's canal on each of both sides of the second recess and, optionally, in the exposed portion of the Schlemm's canal, whereby each of the support elements is made of a material that is decomposable by the tissue of the Schlemm's canal and/or aqueous humor.
