虹膜拉钩联合囊袋张力环在晶状体脱位中的应用

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

目的:评价虹膜拉钩联合囊袋张力环(capsular tension ring,CTR)在外伤性白内障晶状体脱位手术中的应用效果。方法:对23例23眼合并晶状体半脱位的外伤性白内障患者行白内障手术,分为两组。观察组14眼术中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;对照组9眼使用常规白内障超声乳化手术方式。结果:两组间比较,观察组术后视力提高明显,二者比较差异有显著统计学意义(P<0.01);观察组并发症发生率低,二者比较差异有显著统计学意义(P<0.01)。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,视力恢复好。

AIM： To evaluate the application effect of iris hook combined with capsular tension ring（CTR）in traumatic cataract lens dislocation operation.METHODS： Twenty-three patients（23 eyes）of traumatic cataract with lens subluxation underwent cataract operation, and they were divided into 2 groups. Observation group： 14 eyes, iris hooks were positioned to fix capsular bag, CTR was implanted, and then the patients underwent phacoemulsification and were implanted foldable intraocular lenses in the lens capsule. Control group： 9 eyes underwent conventional cataract ultrasonic emulsification operation mode.RESULTS： Comparison between two groups, in the observation group, the postoperative visual acuity was improved, the difference was significant（P〈0.01）; the observation group was lower than the control group in complication rate, and the difference was significant（P〈0.01）.CONCLUSION： The application of iris hook combined with CTR in the treatment of cataract with lens dislocation can improve the operability and safety, reduce operation complication, postoperative intraocular lens can be safe and stable in the capsular bag, visual recovery is good.
