囊袋张力环联合虹膜拉钩在外伤性白内障晶状体脱位中的应用

Application of capsular tension ring combined with the iris hook in the treatment of traumatic cataract with dislocation of lens

目的:评价晶状体囊袋张力环(capsular tension ring,CTR)联合虹膜拉钩在外伤性白内障晶状体脱位手术中的应用效果。方法:对15例15眼合并晶状体半脱位的外伤性白内障患者行白内障手术,术中连续环形撕囊后,使用虹膜拉钩固定囊袋,植入CTR,然后行超声乳化及后房型折叠人工晶状体囊袋内植入。结果:15眼的人工晶状体均处于正位囊袋内。5眼术后12mo最佳矫正视力>0.8;6眼术后12mo最佳矫正视力>0.6,4眼术后视力较术前有提高,无后囊膜破裂,玻璃体进一步脱出,视网膜脱离等并发症的发生。结论:在超声乳化治疗晶状体脱位的白内障手术中运用CTR联合虹膜拉钩,能提高手术的可操作性和安全性,减少手术并发症,术后人工晶状体可以安全稳定地位于囊袋内,且居中性良好。

AIM： To study the clinical effect of capsular tension ring（CTR） and the iris hook in the treatment of traumatic cataract with dislocation of lens. METHODS： Fifteen cases （15eyes） with subluxated cataractous lenses were managed by implanting CTR after continous curvilinear capsulorhexis （ CCC）, fixed by the iris hook, and followed by cataract extraction with phacoemulsification and implantation of posterior chamber intraocular lens. RESULTS： Twelve months after the treatment,the best corrected visual acuity was more than or equal to 0.8 in 5 eyes, more than 0.6 in 6 eyes,and no vision improved in 4 eyes. No intraoperative and postoperative complications such as posterior capsular rupture, prolapse of vitreous and retina detachment occured. CONCLUSION ： The application of CTR and the iris hook in cataract patients with subluxated lens extracted by phacoemulsification can both improve the security and reduce operation complication. Postoperative IOL can be located safely and stably in the capsular centre.
