[Determination of posterior lens capsule status in traumatic cataract with B-ultrasonography].

OBJECTIVE

To determine the status of posterior lens capsule in traumatic cataract with B-ultrasonography.

METHODS

44 eyes of traumatic cataract were studied. The integrity of posterior lens capsule was evaluated with B-ultrasonography before surgery. Cataract extraction was performed under microscope and the status of posterior lens capsule was recorded.

RESULTS

21 eyes showed complete posterior lens capsule in B-ultrasonography. Of them, 19 eyes (90.5%) were confirmed by surgery. Other 23 eyes with posterior lens rupture determined before operation were all confirmed by surgery (100.0%).

CONCLUSION

B-ultrasonography is helpful in evaluating the integrity of posterior lens capsule and choosing the strategy of surgery.
