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。
OBJECTIVE: To compare the effects of modified Blumenthal and Ruit techniques for small incision cataract surgery. Methods: A prospective comparative analysis of 129 patients scheduled for cataract surgery was performed on a nonrandomized basis. Group one (n = 64) adopted the Blumenthal method for the scleral tunnel incision, and Group II (n = 65) used the Ruit method for the temporal scleral tunnel incision. Small incision cataract surgery and intraocular lens implantation through a seamless 6.5 ~ 7.0mm scleral tunnel incision. Patients were examined at 1 day, 1 week and 3 months after operation. Comparison of uncorrected and corrected visual acuity, intraoperative and postoperative complications and surgery caused by astigmatism. RESULTS: Both groups of patients achieved good visual results with few complications. At 3 months postoperatively, the corrected visual acuity was 0.73 for the Blumenthal group and 0.69 for the Ruit group (P = 0.29). Postoperative mean astigmatism was 0.87 (SD: 0.62) D in the Blumenthal group and 0.86 (SD: 0.62) D in the Ruit group. The average astigmatism caused by surgery was 0.55 (SD: 0.45) D in the Blumenthal group and 0.50 (SD: 0.44) D in the Ruit group (P = 0.52). Common complications are a small amount of hyphema and corneal edema. No significant difference in the incidence of complications between the two groups (P> 0.05). Conclusion: Both Blumenthal and Ruit mini-incision cataract surgery can achieve good visual results with few complications.
