表麻下小切口非超声乳化白内障摘除联合IOL植入术的临床研究

目的:探讨表面麻醉下小切口非超声乳化白内障摘除联合人工晶状体植入术的临床效果和安全性。方法:对2007-01/2008-01在我院住院治疗的白内障患者105例113眼实施表面麻醉下小切口非超声乳化白内障摘除联合人工晶状体植入术,观察临床效果。结果:术中麻醉效果明显,显效共107眼(94.7%),有效6眼(5.3%),总有效率达100%,无病例因疼痛无法承受手术而改行球后或球周麻醉。术后第1d裸眼视力≥0.5者65眼(57.5%),>0.8者22眼(19.5%);术后1wk裸眼视力≥0.5者85眼(75.2%),>0.8者17眼(15.0%),随访1mo未发现明显视力下降。术后1wk视力<0.5者1例(0.9%),为糖尿病视网膜病变。术后角膜内皮水肿7眼(6.2%),高眼压4眼(3.5%),经处理后症状均消失。结论:表面麻醉下小切口非超声乳化白内障摘除联合人工晶状体植入术的临床效果确切,安全性高,值得推荐应用。

Clinical research on small incision non-phacoemulsification cataract extraction combined with IOL implantation under topical anesthesia

·AIM:To investigate the effect and safty of small incision non-phacoemulsification cataract extraction combined with intraocular lens(IOL)implantation under topical anesthesia.·METHODS:The cases with cataract in our hospital from January 2007 to January 2008 received small incision non-phacoemulsification cataract extraction combined with IOL implantation under topical anesthesia,and the clinical effect was observed.·RESULTS:The effect of anesthesia was obvious in operation,the excellence rate was 94.7% and good rate was 5.3% and the total effective rate was 100.0%.There was no case who received anesthesia of behind the eyeball and around the eyeball because of pain.There were 65 eyes(57.5%)with naked vision 0.5 or above and 22 eyes(19.5%)with naked vision more than 0.8 in one day after operation.There were 85 eyes(75.2%)with naked vision 0.5 or above and 17 eyes(15.0%)with naked vision more than 0.8 in one day after operation.All of them were followed up for one month and no case was with decressed vision.There was one case(0.9%)with naked vision less than 0.5 because of diabetic retinopathy.There were 7 eyes(6.2%)with corneal endothelium edema,4 eyes(3.5%)with bulbi hypertonia,and all of symptom disappeared after dealing.·CONCLUSION:The effect of small incision non-phacoe-mulsification cataract extraction combined with IOL implantation under topical anesthesia is obvious and safe,so it is worth being used widely.·
