    • A method of treating glaucoma in an eye by managing fluid flow past an implanted shunt having an elastomeric plate and a non-valved elastomeric drainage tube. The plate is positioned over a sclera of the eye with an outflow end of the elastomeric drainage tube open to an outer face of the plate. An inflow end of the drainage tube tunnels through the sclera to the anterior chamber of the eye. The plate may have regions of greater propensity for cell adhesion alternating with regions of lesser cell adhesion. For example, regions of texturing around the plate or drainage tube may be provided to control the size of a bleb that forms over the implant. The effective surface area of the plate may be balanced against a number of fenestrations. The drainage tube has a reduced profile and may be shaped with a non-circular external cross-section to reduce its height. A scleral groove may be used to further reduce the height of the drainage tube on the sclera. A flow restrictor for the early post operative period will immediately lower the intraocular pressure (IOP) and simultanously prevent hypotony.
    • 通过管理流体流过具有弹性体板和非瓣膜弹性体引流管的植入分流器来治疗眼睛中的青光眼的方法。 该板位于眼睛的巩膜上方,弹性体排出管的流出端向板的外表面敞开。 引流管的入流端通过巩膜隧道进入眼睛的前房。 该板可以具有较高的细胞粘附倾向的区域与较小细胞粘附的区域交替。 例如,可以提供围绕板或引流管的纹理区域以控制在植入物上形成的泡沫的尺寸。 板的有效表面积可以与多个开窗平衡。 排水管具有减小的轮廓并且可以被成形为具有非圆形的外部横截面以减小其高度。 可以使用巩膜槽来进一步降低巩膜上引流管的高度。 术后早期流量限制器将立即降低眼内压(IOP)并同时预防低血压。

    • An implantable glaucoma shunt (10) for treating glaucoma in an eye by managing fluid flow past an implanted shunt having an elastomeric plate (40) and a non-valved elastomeric drainage tube (46). The plate is positioned over a sclera of the eye with an outflow end (50) of the elastomeric drainage tube open to an outer face of the plate (42). An inflow (52) end of the drainage tube tunnels through the sclera to the anterior chamber of the eye. The plate may have regions of greater propensity for cell adhesion alternating with regions of lesser cell adhesion. For example, regions of texturing around the plate or drainage tube may be provided to control the size of a bleb that forms over the implant. The effective surface area of the plate may be balanced against a number of fenestrations (64). The drainage tube has a reduced profile and may be shaped with a non-circular external cross - section to reduce its height. A scleral groove may be used to further reduce the height of the drainage tube on the sclera. A flow restrictor for the early post operative period will immediately lower the intraocular pressure (IOP) and simultanously prevent hypotony.
    • 一种用于通过管理流体流过具有弹性体板(40)和无阀弹性体引流管(46)的植入分流器来治疗眼内青光眼的可植入青光眼分流器(10)。 该板位于眼睛的巩膜上方,弹性引流管的流出端(50)通向板(42)的外表面。 引流管的流入端(52)通过巩膜隧道到眼前房。 该板可以具有较高细胞粘附倾向的区域与较少细胞粘附的区域交替。 例如,可以提供围绕平板或引流管的纹理区域以控制在植入物上形成的气泡的大小。 板的有效表面积可以与多个窗孔(64)平衡。 引流管具有减小的外形并且可以成形为具有非圆形外部横截面以降低其高度。 可以使用巩膜凹槽来进一步减小巩膜上引流管的高度。 手术后早期的限流器将立即降低眼压(IOP)并同时防止低眼压。
