方法：对75例80眼白内障应用圈垫器和劈核刀进行劈核取出，植入后房型人工晶状体，观察术后视力、散光度、及术中、术后并发症。随访3～12mo。

结果：术后第1d视力0.3～0.5者37眼，≥0.6者21眼，术后1mo 0.3～0.5者43眼，≥0.6者26眼。角膜散光在术后1wk为1.75±0.55D，与术前0.85±0.29D相比有显著差异(P<0.05)，术后1mo 0.92±0.48D和3mo 0.89±0.35D与术前比较无显著差异(P>0.05)。4眼术中后囊破裂，1眼人工晶状体植入囊袋内，3眼人工晶状体植入睫状沟内。术后角膜内皮波纹状水肿2眼，术后3d左右消退； 斑块状水肿2眼，术后2wk内消退。一过性高眼压2眼。

结论：小切口圈垫式劈核白内障囊外摘除人工晶状体植入术治疗白内障术后效果好，手术成本低，操作简便，并发症小，值得临床推广应用。

METHODS:A total of 75 cases(80 eyes), in which loop-pad and chop knife were performed to chop nucleus before implanting intraocular lens. Visual acuity, postoperative astigmatism degree, intraoperative and postoperative complications were observed. The post-operative follow-up periods ranged from 3 to 12mo.

RESULTS: The visual acuity was 0.3-0.5 in 37 eyes and 0.6 or better in 21 eyes at 1d, while was respectively in 43 eyes and in 26 eyes at 1mo. Compared with preoperative astigmatism(0.85±0.29D), there were significant difference at postoperative 1wk(1.75±0.55D)(P<0.05), while there were no significant difference at postoperative 1mo(0.92±0.48D)and 3mo(0.89±0.35D)(P>0.05). Intraoperative posterior capsule rupture occurred in 4 eyes, which implantation was successful in 1 eye and 3 eyes was managed viaciliary sulcus. Two eyes had dermatoglyphic pattern edema in corneal endothelium which recovered after about 3d. Two eyes had local patchy opacities which recovered in 2wk. Two eyes had transient high intraocular pressure.

CONCLUSION: The surgery is efficient, low cost, easy process and less complications, it is worth to be popularized.
