目的：探讨开放囊袋-人工晶状体(IOL)单襻睫状沟固定术治疗先天性晶状体半脱位的安全性和有效性。
方法：收集2011-03-01/2013-12-31影响视力的先天性晶状体半脱位患者10例13眼，做角巩膜缘隧道切口，环形撕囊后，使用虹膜拉钩，固定脱位晶状体，完成超声乳化手术。植入IOL，剪开晶状体脱位一侧囊袋，翻转前囊，上襻位于囊袋内，下襻单针经缝合固定于睫状沟。
结果：所有患者最佳矫正视力均不同程度提高，IOL稳定，没有进展性偏位。
结论：虹膜拉钩可以稳定脱位的晶状体，使超声乳化手术顺利完成。开放下方囊袋，IOL呈半游离状态，下襻睫状沟缝合固定可维持IOL的长期稳定，避免囊袋进行性偏移，造成IOL偏位。

[Abstract]
AIM: To evaluate the safety and efficiency of the open capsule-single loop intraocular lens(IOL)ciliary sulcus fixation for the treatment of congenital subluxation lens.
METHODS: Ten patients(13 eyes)with congenital subluxation lens were included. After conventional tunnel incision and continuous curvilinear capsulorhexis, iris hooks were used to fix the luxation lens helped the phacoemulsification(phaco)procedure and IOL implantation into capsular bag. The inferior capsular bag was opened. The IOL prolapsed from the bag and was half packaged. The lower loop was fixed to the ciliary sulcus by suturing to avoid the possible dislocation.
RESULTS: The best corrected visual acuity(BCVA)was increased in all of the patients without any serious complication. The IOL kept stable in 12mo.
CONCLUSION: The iris hooks can fix subluxation lens and facilitate the phaco. Open capsular bag makes IOL half-free and single suture the lower IOL loop in ciliary sulcus. It can avoid dislocation of the IOL due to progressive weakening of the zonular fibers.
