A variation to standard trabeculectomy is described, whereby the trabecular tissue flap is not completely excised, but dissected free, hinged at its nasal end and sutured diagonally across the scleral bed, to act as a wedge between the scleral flap and its bed, in an attempt to decrease the tendency of the sclera to scar into a watertight barrier. In addition, it is suggested that the trabecular flap acts as a wick that aids in the filtration of the aqueous humour. The technique has been used in 24 eyes with good to excellent, short-term, post-operative intraocular tension control in all but 2 patients. Mil complications like transient flat anterior chamber or blood cells in the aqueous occur at rates comparable to other filtering procedures.
本文描述了一种标准小梁切除术的变体方法，即小梁组织瓣并非完全切除，而是游离后在其鼻侧端形成铰链，并斜向缝合于巩膜床，充当巩膜瓣与其床之间的楔子，以试图降低巩膜瘢痕化形成水密屏障的倾向。此外，有人认为小梁瓣起到灯芯作用，有助于房水滤过。该技术已应用于24只眼，除2例患者外，其余患者术后短期眼压控制良好至极佳。轻微并发症如短暂性无前房或房水中出现血细胞的发生率与其他滤过手术相当。
