Pars plana lensectomy by ultrasonic fragmentation appears to be the treatment of choice for extraction of subluxated and dislocated lenses. The closed system technique allowed extraction of 11/11 subluxated lenses without operative or postoperative complications with an average observation period of 4.5 years. The technique was employed in four traumatically dislocated lenses in eyes with accompanying traumatic pathology requiring additional surgical procedures, i.e., cryoretinopexy and scleral buckling. There were no complications in 4/4 eyes with an average observation period of 1.5 years. Pars plana lensectomy avoids many of the complications of the open-sky limbal approach i.e. anterior synechiae, vitreous incarceration, wound dehiscence, aphakic or pupillary block glaucoma, bullous keratopathy, epithelial ingrowth, stromal ingrowth or outgrowth and surgically induced astigmatism.
超声粉碎晶状体平坦部切除术似乎是半脱位和脱位晶状体摘除的首选治疗方法。采用闭合系统技术摘除了11枚半脱位晶状体，均未出现手术中和术后并发症，平均观察期为4.5年。该技术应用于4例伴有外伤性病变（需要额外手术操作，即冷冻视网膜固定术和巩膜扣带术）的外伤性脱位晶状体。4只眼中有4只未出现并发症，平均观察期为1.5年。晶状体平坦部切除术避免了开放式角膜缘入路的许多并发症，即虹膜前粘连、玻璃体嵌顿、伤口裂开、无晶状体性或瞳孔阻滞性青光眼、大疱性角膜病变、上皮内生、基质内生或外生以及手术性散光。
