Clinical Significance of B- mode Ultrasonic Scanning in Preoperative Examination for Cataract Patients

Objective To evaluate clinical significance of B-mode ultrasonic scanning as a preoperative eye examination on the diagnosis,postoperative vision and prognosis for pediatric,traumatic and senile cataract patients.Methods 68 eyes of 58 cataract operative cases underwent B-mode ultrasonic scaning preoperatively,and were compared with the intra operative findings along with postoperative examination.Results There are three characteristic echograms respectively for each kind of cataract patients with 95.59% diagnostic coincidence rate among 68 eyes.Conclusions B mode ultrasonic scanning of eye examination plays an important role in the operative selection and prognostic evaluation because of its convenient procedure with high quality picture of crystalline lens and direct figure diagnosis.
