小切口非超声乳化人工晶状体植入术临床研究

Small-incision non-phacoemulsification intraocular lens implantation.

目的 探讨小切口非超声乳化白内障摘出及人工晶状体植入术的方法及效果。方法 在上方角膜缘后做 5 5mm角巩膜隧道小切口 ,对 6 7例 ( 81眼 )老年性白内障行晶状体分割术摘出 ,并植入人工晶状体。对照组采用现代白内障囊外摘出(ECCE)及人工晶状体植入术进行前瞻性研究。结果 术后 3天后裸眼或球镜矫正视力≥ 0 .5者小切口组占 91 36 % ,对照组占6 3 16 % ,两组之间差别具有非常显著性 (P <0 .0 1) ,小切口组术后第 3日。 1周、1月和 3月时的裸眼或球镜矫正视力的平均值均高于对照 (P <0 .0 5 )结论 小切口白内障摘出及人工晶状体植入术可获得与超声乳化术相近的术后结果 ,而且对Ⅳ级和Ⅴ级硬核白内障则更安全 ,且投资小 。

Objective To evaluate the method and effectiveness of small-incision non-phacoemulsification and intraocular lens implantation.Methods ECCE and intraocular lens implantation was performed through a 5.5 mm incision by means of scleral tunnel behand the upper limbal on 81 eyes of 67 patients with senile cataract.The prospective study was made through the regular morden ECCE and intraocular lens implantation in the control group.Results The postoperative visual acuity or corrected visual acuity with sperical lens ≥0.5 was 91.36% in small-incision group, and 63.16% in the control group, the difference between two groups was significent(P<0.01).The mean value of visual acuity and corrected visual acuity with sperical lens at 3 days, one week,one month and three months after operation in small-incision group was higher than that in the control group (P<0.05).Conclusion Small-incision cataract extraction and intraocular lens implantation has the similar effectiveness with phacoemulsification,which is safer and cheaper to the hard mucleus cataract above Ⅳ level,and has a useful clinic value.
