表麻下角巩膜缘刺入法治疗IOL植入术后发性白内障

Therapy of after cataract by needling through corneoscleral limbus tunnel incision with topical anesthesia

摘要:

目的:探讨在表面麻醉情况下从角巩缘刺入进行针对白内障人工晶状体(IOL)术后后囊膜混浊划开与YAG激光后囊膜切开治疗方法对比。评价其临床效果及安全性及稳定性。方法:在表面麻醉下选择角巩缘用钻石刀刺入1mm,用自制弯形刺囊针深入人工晶状体后面对其增厚囊膜点状划开,观察临床效果及并发症。结果:患者29例32眼,划开前视力0.06～0.1,划开后视力1.0以上占69.9%,患者无任何不适,无任何并发症。结论:选用瑞士进口钻石刀在表面麻醉下角巩缘区刺开,方法简便易行,患者无任何不适,无任何并发症,达到立竿见影的效果,可以替代YAG激光的治疗。

Abstract:

AIM:To compare the therapeutic method of posterior capsulorhexis with topical anesthesia by needling through corneoscleral limbus tunnel incision with that of YAG laser posterior capsulotomy on posterior capsular opacification.To evaluate the efficacy,safety and stability of posterior capsulorhexis.METHODS:An 1mm tunnel incisoon was stuck into by a diamond cutter from the cornescleral limbns atfer topical anesthesia was performed Postorior of intraoular lens was pricked into by a curved needle for dividing the thichened postorior capsiles.The efficacy and complication were observed.RESULTS:In 29 patients(32 eyes),whoes visual acuity was 1.0 account for 69.9% postoperatively,compared with preoperatively the visual acuitiy 0.06-0.1 without any discomfort and complication for the patients.CONCLUSION:Use of imported diamond cutter from Swizorland to discissio through tunnel incision is convenient and easy without any discomfort and complication for the patients.This method can be substituted by YAG laser posterior capsulotomy.
