摘　　要：目的用超声生物显微镜观察老年性白内障囊外摘除术及后房型人工晶体植入术后房角的变化及相关因素。方法用超声生物显微镜观察老年性白内障囊外摘除术及后房型人工晶体植入术后，３１例（４１只眼）的房角改变。结果虹膜周边前粘连６只眼，瞳孔变形１２只眼，均与人工晶体襻的位置有关；并非所有非囊袋内固定的人工晶体襻均位于睫状体沟；术后残留的晶体皮质，术后３个月仍存留，较多晶体皮质的残留可引起周边虹膜膨隆、房角变窄。结论后房型人工晶体植入术后房角的改变与人工晶体襻的位置及残留的晶体皮质有关；建议尽可能采用囊袋内植入人工晶体，避免过多的晶体皮质残留。Objective To observe the changes of anterior chamber angle after extracapsular cataract extraction (ECCE) with posterior chamber implantation of intraocular lens (IOL) and discuss the associated factors. Methods The changes of anterior chamber angle in 31 cases (41 eyes) with senile cataract were observed with ultrasonic biomicroscopy after ECCE and posterior chamber implantation of IOL. Results (1) There were 6 eyes with peripheral anterior synechia of the iris, 12 eyes with abnormal pupillary configuration, which were related to the position of IOL haptics. (2) The IOL haptics fixed out of the capsular bag were not all fixed at the ciliary grooves. (3) After postoperative 3 months, the residual cortex of the lens still existed. Too much residual cortex in the eye caused postoperative peripheral iris bombe and narrowing of chamber angle. Conclusion The changes of anterior chamber angle after posterior chamber implantation of IOL are related to the position of IOL haptics and much residual cortex must be avoided.
