目的:探讨平面劈核方法在小切口硬核白内障摘除术的临床效果。方法:用穿刺碎核镊及拦截型劈核刀劈开Ⅳ级以上硬核白内障,完成小切口硬核白内障摘除术。结果:对86例86眼Ⅳ级以上硬核白内障进行平面劈核,一次性劈开率为100%。86眼的晶状体核经6mm长切口均安全娩出。术后3,7d视力≥0.5者分别为70眼(81%)和79眼(92%)。术后角膜散光度为0.85±0.55D。结论:穿刺碎核镊及拦截型劈核刀平面劈核法适合小切口非超声乳化硬核白内障摘除手术,是小切口白内障手术理想的劈核方法。

AIM:To investigate the clinical effect of plane chopping method in small incision hard nucleus cataract surgery. ·METHODS:Hard nucleus(≥Ⅳ) small incision cataract surgery was performed with the puncture forceps and split nucleus knife. ·RESULTS:Totally 86 cases of hard nucleus cataract (≥Ⅳ) underwent the plane chopping surgery and succeeded with the 6mm incision. Visual acuity≥0.5 in 70 eye (81%) and 79 eyes (92%) in postoperative day 3 and day 7,respectively. Postoperative astigmatism degree was 0.85±0.55D. ·CONCLUSION:The puncture nucleus-forceps and plane chopping is a suitable and ideal chopping method for small incision hard nucleus cataract.
