A surgical technique for implanting a posterior chamber intraocular lens (IOL) in eyes without capsular or zonular support is presented. A 10-0 polypropylene suture attached to a standard needle is tied to the apex of each haptic and passed transclerally through the ciliary sulcus to secure the haptics at the 3 o'clock and 9 o'clock meridians. This technique produced good visual results in six aphakic patients who were contact lens intolerant, two patients in whom capsular or zonular rupture at the time of cataract surgery precluded standard nonsuture fixation techniques, one patient who had intracapsular cataract extraction for a subluxated, cataractous lens, and one patient who had secondary IOL implantation in combination with penetrating keratoplasty for aphakic bullous keratopathy. Advantages over other techniques of posterior chamber lens implantation in the absence of capsular support include technical ease, avoidance of iris fixation, and more precise placement of scleral fixation sutures, thus minimizing IOL decentration.
介绍了一种在无囊膜或悬韧带支撑的眼中植入后房型人工晶状体（IOL）的手术技术。将一根连接标准针的10-0聚丙烯缝线系在每个襻的顶端，经巩膜穿过睫状沟，在3点和9点子午线处固定襻。该技术在6例不能耐受隐形眼镜的无晶状体患者、2例白内障手术时囊膜或悬韧带破裂而无法采用标准非缝线固定技术的患者、1例因晶状体半脱位行白内障囊内摘除术的患者以及1例因无晶状体大泡性角膜病变联合穿透性角膜移植术行二期IOL植入的患者中取得了良好的视觉效果。与在无囊膜支撑情况下进行后房型晶状体植入的其他技术相比，该技术的优点包括操作简便、避免虹膜固定以及巩膜固定缝线的放置更精确，从而使IOL偏心最小化。
