目的:比较改良的Blumenthal和Ruit手法小切口白内障手术的效果。方法:对129例预定行白内障手术的患者进行非随机分组的前瞻性比较分析。组一(n=64)采用Blumenthal方法巩膜上方隧道切口,组二(n=65)采用Ruit方法颞侧巩膜隧道切口。手法小切口白内障手术及人工晶状体植入术通过一个无缝合的6.5~7.0mm巩膜隧道切口。在术后1d,1wk和3mo检查患者。比较术后未矫正及矫正视力,术中及术后并发症以及手术引起的散光。结果:两组患者都获得了很好的视觉结果,并发症很少。术后3mo,Blumenthal组的矫正视力是0.73,Ruit组的矫正视力是0.69(P=0.29)。术后平均散光:Blumenthal组是0.87(SD:0.62)D,Ruit组是0.86(SD:0.62)D。手术引起的平均散光Blumenthal组是0.55(SD:0.45)D,Ruit组是0.50(SD:0.44)D(P=0.52)。常见的并发症是少量的前房出血和角膜水肿。两组并发症的发生率无显著差别(P>0.05)。结论:Blumenthal和Ruit手法小切口白内障手术都能获得很好的视觉结果,并发症很少。

·AIM:To compare the efficacy and visual results of the modified Blumenthal and Ruit techniques for manual small-incision cataract surgery(MSICS).·METHODS:This was a prospective,non-randomized comparison of 129 patients with senile cataracts scheduled to undergo routine cataract surgery via either a superior scleral tunnel incision,i.e.,the Blumenthal technique(group 1,n=64)or a temporal scleral tunnel incision,i.e.,the Ruit technique(group 2,n=65).MSICS and intraocular lens implantation were performed through an unsutured 6.5-to 7.0-mm scleral tunnel incision.Uncorrected and corrected visual acuity,intraoperative and postoperative complications,and surgically induced astigmatism calculated by simple subtraction were compared.Patients were examined 1 day,1 week,1 month,and 3 months after surgery.·RESULTS:Both groups achieved good visual outcomes with minor complications.Three months after surgery,the corrected visual acuity was 0.73 in the Blumenthal group and 0.69 in the Ruit group(P=0.29).The average(SD)postoperative astigmatism was 0.87(0.62)diopter(D)for the Blumenthal group and 0.86(0.62)D for the Ruit group.The mean(SD)surgically induced astigmatism was 0.55(0.45)D and 0.50(0.44)D for the Blumenthal and Ruit groups,respectively(P=0.52).Common complications were minimal hyphema and corneal edema.There was no statistically significant difference in the complication rate between the groups(P>0.05).·CONCLUSION:In MSICS,both the Blumenthal and Ruit techniques achieve good visual outcomes,with low complication rates.·
