摘　　要：目的:利用超声生物显微镜评价两种后房型人工晶状体在眼内的稳定性。方法:应用超声生物显微镜测量两种后房型人工晶状体在眼内的偏心量、倾斜度、前房深度、观察人工晶状体襻的确切位置和人工晶状体襻与周围组织的关系。结果:术后各组1wk与1mo的偏心量、倾斜度相比,差异无统计学意义(P>0.05);术后1wk时,比较两组的偏心量、倾斜度,差异均无统计学意义(P>0.05);术后1mo时,比较两组的偏心量、倾斜度,差异均无统计学意义(P>0.05)。术后各组1wk与1mo的前房深度相比,差异无统计学意义(P>0.05);术后1wk时,比较两组前房深度,差异有统计学意义(P<0.05);术后1mo时,比较两组前房深度,差异有统计学意义(P<0.05)。结论:一片式折叠人工晶状体较三片式折叠人工晶状体在眼内具有更好的稳定性。UBM能对人工晶状体襻的位置及其对周围组织的影响进行很好的观察。AIM：To evaluate the stability using ultrasonic biomicroscope（UBM） in eyes having phacoemulsification with implantation of 2 types posterior chamber intraocular lens （PC-IOL）. METHODS：The degree of PC-IOL decentration,tilt and anterior chamber depth（ACD） were measured by UBM,while locating the haptics and observing the relationships of haptics on uveal tissue. RESULTS：There was no significant change during the 1 month follow-up period in decentration or tilt in each group （P0.05）.There was no significant difference among the groups in IOL decentration or tilt at any time point （P0.05）.There was no significant change during the 1 month follow-up period in ACD in each group （P0.05）. There was significant difference among the groups in ACD at 1 week,1 month after surgery （P0.05）. CONCLUSION：The stability of 1-piece IOL in eyes was better than that of 3-piece IOL;UBM can locate the haptics and observe the relationships of haptics on uveal tissues better.
