目的：探讨后房型人工晶状体睫状沟缝线固定术在白内障术中韧带断裂及后囊破裂后人工晶状体二期植入，外伤性白内障、晶状体脱位等无晶状体后囊膜术眼中的应用及术后并发症。

方法：选取我科2007-02/2012-11 采用后房型人工晶状体缝线固定术患者31例32眼，均获得较满意的效果。

结果：术后随访3mo～1a，矫正视力>0.5者9眼(28%)； 0.1～0.5者17眼(53%)； <0.1者6眼(19%)。出现术中睫状体穿刺口出血、术后角膜水肿、角膜散光、悬吊线松弛断裂、人工晶状体偏位等主要并发症。

结论：后房型人工晶状体缝线固定术是目前无后囊或后囊膜晶状体悬韧带大范围缺损的手术首选，但还有许多手术并发症有待进一步解决。

AIM: To discuss the application and complications of ciliary sulcus suture fixation of posterior chamber in secondary intraocular lens(IOL)implantation after rupture of the ligament and posterior capsule, and posterior capsular surgeries in aphakic eyes including traumatic cataract, dislocation of the lens, etc.

METHODS: From February 2007 to November 2012, 31 patients(32 eyes)were received suture fixation of posterior chamber IOL implantation in our department and got satisfactory results.

RESULTS: The corrected visual acuity was >0.5 in 9 eyes(28%), 0.1-0.5 in 17 eyes(53%), and <0.1 in 6 eyes(19%)from 3 months to 1 year after operation. The main complications included bleeding from the puncture site of ciliary body, postoperative corneal edema, corneal astigmatism, loose or parted suspending suture, and IOL dislocation, etc.

CONCLUSION: The suture fixation of posterior chamber IOL implantation is the first operation choice currently for eyes without posterior capsule or eyes with severe defects of posterior capsular lens suspensory ligament, but many complications in the operation need to be solved.
