Abstract
A glaucoma drain for non-penetrating deep sclerotorny is made of non-resorbable and hydrophilic synthetic material. The drain is configured to be entirely covered by the scleral flap and totally inserted in the intrascleral space. It comprises a transverse bar (110) at one front end of the drain and a longitudinal body (120) extending longitudinally from said transverse bar. The transverse bar (110, 10) is configured to run along and cover the Schlemm's canal (CS) and the opposite ends are configured to penetrate beneath the deep sclera inside the Sclernm's canal. A hole (125) between the arms of the bar provides a target for possible YAG laser micro-punctures.
Claims26
A glaucoma drain for deep non-penetrating sclerectomy, the glaucoma drain being made of hydrophilic nonresorbable synthetic material and being configured to be covered by the scleral flap and to be inserted inside an intrascieral space, the glaucoma drain comprising a transverse bar at a front end thereof and a longitudinal body extending longitudinally from said transverse bar, opposite ends of said transverse bar being configured to penetrate inside Schlemm's canal.
A glaucoma drain for deep non-penetrating sclerectomy, the glaucoma drain being made of hydrophilic non-resorbable synthetic material and being configured to be covered by the scleral flap and to be inserted inside an intrascleral space, the glaucoma drain comprising a transverse bar at a front end thereof and a longitudinal body extending longitudinally from said transverse bar, a front edge of the transverse bar projects anteriorly in order to tension the trabeculo-descemetic membrane.
A method for reducing intraocular pressure in the anterior chamber of the eye comprising the steps of:
- providing a hydrophilic, non-resorbable glaucoma drain having a longitudinal body and a transverse bar at a front end of the longitudinal body, performing a deep non penetrating sclerectomy, thereby forming a scleral flap and an interscleral space, introducing the drain into the intrascleral space and introducing opposite ends of the transverse bar inside Schlemm's canal and closing the scleral flap.
