To evaluate by ultrasound biomicroscopy (UBM) the exact position of a posterior chamber intraocular lens (PC IOL) implanted above a posterior capsule tear and to correlate the findings with the outcomes and complication rate.
Department of Ophthalmology, Rabin Medical Center, Petah Tiqva, Israel.
In a retrospective noncomparative case series, 36 patients (36 eyes) who had extracapsular cataract extraction (ECCE) complicated by capsular tear were evaluated. In all cases, a PC IOL was implanted above the remnant of the capsule without suturing. Ultrasound biomicroscopy was performed to study the exact position of the optic and haptic. The outcomes and complication rate were determined from patient examinations performed during a follow-up of 1 to 6 years.
Optic tilt was found in 20 of 36 patients (56%). In 17 patients (47%), both haptics were located in the sulcus. In 15 patients (42%), 1 haptic was observed in the sulcus and 1 in the bag or elsewhere. No correlation was found between the position of the optic and the location of the haptics. Minimal postoperative complications were observed, and only 1 patient required another surgery for a dislocated IOL.
By UBM, half the patients had optic tilt and more than half the IOLs were not implanted in the sulcus, the intended location.
通过超声生物显微镜（UBM）评估植入后囊膜撕裂上方的后房型人工晶状体（PC IOL）的确切位置，并将结果与手术效果及并发症发生率相关联。
以色列佩塔提克瓦拉宾医疗中心眼科。
在一项回顾性非对照病例系列研究中，对36例（36只眼）因囊膜撕裂而接受了囊外白内障摘除术（ECCE）的患者进行了评估。所有病例均在未缝合的情况下将PC IOL植入囊膜残余上方。采用超声生物显微镜检查来研究晶状体光学部和襻的确切位置。通过对患者进行1至6年随访期间的检查来确定手术效果及并发症发生率。
36例患者中有20例（56%）出现晶状体光学部倾斜。17例患者（47%）的两个襻均位于睫状沟。15例患者（42%）的一个襻位于睫状沟，另一个襻位于囊袋内或其他部位。未发现晶状体光学部位置与襻的位置之间存在相关性。术后观察到的并发症极少，只有1例患者因人工晶状体脱位需要再次手术。
通过UBM检查发现，半数患者存在晶状体光学部倾斜，超过半数的人工晶状体未植入预期位置睫状沟。
