摘要
目的 评价 3种隧道式切口在白内障超声乳化吸除术的中应用效果。 方法 采用透明角膜 (Ⅰ组 )、角膜缘 (Ⅱ组 )、反弧形巩膜 (Ⅲ组 )隧道式切口 ,对 5 6 8例 (5 88眼 )老年性、并发性、外伤性白内障行超声乳化吸除 ,并植入Acrysof折叠式人工晶状体或直径 5 .5mm的人工晶状体。 结果 3组在术后 1周、2周、1个月视力≥ 0 .5者分别占 74.6 %、79.5 %、77.4% ,83 .5 %、86 .4%、84.6 % ,88.6 %、89 .7%、87.4% ;角膜散光以角膜切口组为高 ,差异有显著性 (P <0 .0 5 )。术后 3个月时 3组的角膜散光已经基本接近 (P >0 .0 5 )。 结论 3种隧道式切口均是白内障手术较佳的切口。
Objective To evaluate the therapeutic effects of phacoemulsification with foldable intraocular lens implantation through three tunnel incisions. Methods The surgery was performed through clarity cornea,limbus and reverse arc sclera tunnel incisions on 588 eyes of 568 patients with senile,complicated and traumatic cataracts. Results Postoperatively,the visual acuities were 0.5 or better in 74.6%、79.5%、77.4%;83.5%、86.4%、 84.6% 、88.6%、89.7%、87.4%of the eyes on one week,one month,three months(P<0.05).The mean postoperative astigmatism was cornea incision for high.There was also statistical difference prominence(P<0.05).The mean postoperative astigmatism was almost the same as compared between the three tunnel incision groups. Conclusion Three tunnel incisions for PHACO and IOL surgery were fine incisions.
