Abstract

PURPOSE

To describe a bimanual method for management of posteriorly dislocated large nucleus fragment using standard chopper.

METHODS

A 23G assistant handheld endoilluminator was used as light source through inferonasal self-sealing port, while the large nuclear fragment was broken into smaller fragments using phacofragmatome and standard phaco chopper.

RESULTS

A case of posteriorly dislocated large nuclear fragment was operated using this technique. The time taken for phacofragmentation was significantly reduced, as well as the ultrasound energy required for the same. There was no port site complication.

CONCLUSION

This technique allows greater maneuverability and reduces amount of ultrasound energy used by dividing nucleus into small fragments in vitreous cavity.

摘要

目的

描述一种使用标准劈核器处理后脱位大核碎片的双手操作方法。

方法

通过鼻下自封闭端口使用23G辅助手持内照明器作为光源，同时使用晶状体超声粉碎器和标准超声乳化劈核器将大核碎片破碎成较小的碎片。

结果

采用该技术对1例后脱位大核碎片病例进行了手术。晶状体超声粉碎所需时间显著缩短，所需超声能量也显著减少。未发生穿刺口并发症。

结论

该技术可提高操作的灵活性，并通过在玻璃体腔中将核粉碎成小碎片来减少超声能量的使用量。
