目的:探讨术前 B超检查对外伤性白内障后囊损伤的判定及应用价值。方法:外伤性白内障 60只眼术前采用 B超检查以判定晶体后囊情况,显微镜下行外伤性白内障摘除,直接观察术中后囊情况并记录。结果: 36只眼术前 B超检查后囊完整,其中 33只眼术中证实后囊完整,符合率 91.7%, 24只眼术前 B超检查后囊不完整,术中证实 23只眼后囊存在大小不等的破损,符合率 95.8%。结论:外伤性白内障术前 B超检查为非侵入性无痛性检查,操作简便,准确率高,对术前晶体后囊状态可提供重要的参考,可作为术前了解外伤性白内障后囊破损情况的常规检查方法,对手术操作和选择术式有指导意义。%Objective:To evaluate the diagnostic value of B- Ultrasound Scan on Traumatic Cataract.Methods:60 eyes of traumatic cataract underwent preoperative B- ultrasonograph and intraoperative microscopic examination to evaluate the situation of posterior lens capsule.Results:95.8% cases has been confirmed the evaluation of B- Ultrasound Scan after the operations.Conclusions:For traumatic cataract,B- Ultrasound Scan is a harmless and accurate diagnostic method.
