Abstract

A method for improving the draining of aqueous humor in an eye of a living being and a device for widening the Schlemm's canal is 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 exposing two opposite openings into the Schlemm's canal into which an expanding medium is injected into the Schlemm's canal; formation of a slitlike passageway connecting the aqueous humor-permeable Descemet-membrane with the subscleral space is realized by detaching the Descemet-membrane on the area of the Schwalbe's line by means of a slight pressure force; and subsequently, the first scleral flap folded back, after severance of the second scleral flap, for placement upon a support surface formed as a consequence of the incision of the second lamellar section. Subsequently, a viscous medium is injected into a subscleral space formed behind the first scleral flap and the first scleral flap is rejoined to the sclera.
