目的 探讨儿童超声乳化白内障吸除联合丙烯酸酯 (Acrysof)折叠式人工晶状体(intraocularlenses ,IOL)植入术的手术疗效。方法 对行超声乳化白内障吸除联合Acrysof折叠式IOL植入术的超声乳化组患儿 6 1例 (76只眼 )及行现代囊外白内障摘除联合聚甲基丙烯酸甲酯(polymethylmethacrylate ,PMMA)硬性IOL植入术的囊外摘除组患儿 5 9例 (77只眼 ) ,术后随访 6～ 18个月 ,观察、比较术后视力、并发症和Q 开关掺钕钇铝石榴石 (Q switchedneodymium :yttriumaluminumgarnet,Nd :YAG)激光后囊膜切开手术率的情况。结果 超声乳化组和囊外摘除组脱盲率分别为10 0 %、90 6 % ;脱残率分别为 72 6 %、5 1 5 % ;后囊膜混浊发生率依次为 6 6 %、80 5 % ,Nd :YAG激光后囊膜切开手术率依次为 2 6 %、6 4 9%。两组比较 ,脱盲率差异无显著性 (P >0 0 5 ) ;脱残率差异有显著性 (P <0 0 5 ) ;术后各种并发症的发生率和Nd :YAG激光后囊膜切开手术率差异有非常显著性(P <0 0 1)。结论 超声乳化白内障吸除联合Acrysof折叠式IOL植入术 ,以手术切口小、组织损伤轻、负压吸引可最大限度清除残存晶状体上皮细胞等特点及IOL材料优良的组织相容性 ,使手术疗效显著 ,术后并发症减少 ;Acrysof折叠式IOL在治疗儿童白内障手术中?
Objective To investigate the effect of phacoemulsification combined with Acrysof intraocular lenses (IOL) implantation. Methods Sixty-one children (76 eyes) with phacoemulsification combined with Acrysof foldable IOL implantation were treated with modern extracapsular cataract extraction combined with polymethylmethacrylate (PMMA) Fifty-nine patients (77 eyes) with IOL implantation underwent extracranial resection and were followed up for 6 to 18 months. The postoperative visual acuity, complications and Q switched neodymium : yttriumaluminumgarnet, Nd: YAG) laser posterior capsulotomy operation rate of the situation. Results The rate of blindness in phacoemulsification group and extracapsular excision group was 100% and 906% respectively. The percentage of disability was 72.6% and 51.5% respectively. The incidences of posterior capsule opacity were respectively 6 6% and 80 5% The Nd: YAG laser posterior capsulotomy rates were 26% and 649%, respectively. There was no significant difference between the two groups (P> 0.05); the difference of disability rate was significant (P <0 05); the incidence of postoperative complications and Nd: YAG laser posterior capsule The difference of incision rate was significant (P <0.01). Conclusion Phacoemulsification combined with Acrysof foldable IOL implantation has the advantages of small surgical incision, light tissue injury and negative pressure to minimize the residual lens epithelial cells and the excellent histocompatibility of IOL, Significant reduction of postoperative complications; Acrysof foldable IOL in the treatment of children with cataract surgery?
