Clinical significance of preoperative B-ultrasonography for traumatic cataract

Objective To approach the clinical significance of B ultrasonography in detection of the break of posterior lens capsule in traumatic cataract Methods 30 patients (30 eyes) of traumatic cataract underwent preoperative B ultrasonography and intraoperative microscopic examination to evaluate the status of posterior lens capsule Results 14 eyes showed posterior lens capsule unbroken in B ultrasonography Of them, 12 eyes were confirmed by surgery 16 eyes showed rupture of the posterior lens capsule in B ultrasonography Among them 14 eyes were confirmed by surgery and in 2 eyes there was no break at the posterior lens capsule Comclusions B ultrasonography for preoperative traumatic cataract is harmless, painless, simple in operative procedure and accurate, thus it can be used as a routine examination to show the status of posterior lens capsule in traumatic cataract
