摘　　要：目的　评价弹性开放襻一体型前房型人工晶状体 (anterchamberintraocularlens,AC IOL)植入术的疗效及其安全性。方法　应用超声生物显微镜观察 2 0例 (2 0只眼 )弹性开放襻一体型AC IOL植入术后患者IOL襻的位置 ,以及其与虹膜及房角结构的关系 ,从而评价IOL对眼前段结构的影响。随访时间 6～ 2 0个月。结果　 40个IOL襻中 ,2 6个襻固定于房角隐窝 ;14个襻 (8只眼 )穿过虹膜侵入至睫状体实质内 ,并伴有反复发作的葡萄膜炎。术后 8只眼虹膜前粘连与IOL襻有关。结论超声生物显微镜检查是动态了解IOL对眼前段结构影响的有效方法。AC IOL襻的设计有待进一步改进。Objective To evaluate the therapeutic effects and safety of flexible open loop anterior chamber intraocular lens (FOAC IOL). Methods By ultrasound biomicroscopy, the positions of the haptics of FOAC IOL in 20 patients (20 eyes) and the relationships of the haptics with iris and anterior chamber angle structures were observed postoperatively to evaluate the impact of these lenses on the structures of ocular anterior segment. Follow up duration was from 6 to 20 months. Results Among 40 IOL′s haptics, twenty six haptics were fixed at the recess of the chamber angle ;and other fourteen haptics penetrated the iris and invaded into the ciliary stroma, which caused recurrent uveitis. There was 1 eye with eccentric lens. There were 8 eyes with anterior synechiae of iris, which were related to the haptics of intraocular lens. Conclusions Ultrasound biomicroscopy works well in dynamic observation of the influence of intraocular lens on ocular anterior segment. The haptics of flexible open loop anterior chamber intraocular lens should be modified.
