摘　　要：目的探讨斜向切核及捆绑式娩核在白内障摘除术中的应用价值和临床疗效。方法利用自行设计的白内障线切核器对86例(97只眼)老年性白内障患者应用斜向切核及捆绑式娩核的方法施行白内障摘除及折叠式人工晶状体植入术。评价其疗效。结果97只眼中,术中晶状体后囊膜破裂1只眼;前房出血2只眼;眼压升高6只眼;角膜内皮轻度水肿8只眼,均于5 d内消退。术后1周矫正视力≥0．5者78只眼(80．41％),3个月为91只眼(93．81％);术后3个月矫正视力≥1.0者66只眼(68．04％)。术后1周及3个月角膜平均散光度与术前相比差异均无统计学意义(P>0．05)。结论该方法能够有效地解决适于折叠式人工晶状体植入的小切口白内障摘除术中的手法碎核及娩核问题,而且操作简便、灵活安全。Objective To investigate the effects of oblique nuclear chopping and nuclear extraction by binding procedure （ ONCNEB ） in cataract extraction. Methods Extracapsular cataract extraction by ONCNEB with foldable IOL implantation was performed in 86 senile cataract cases （97 eyes） by using a line-shaped cataract nuclear chopping apparatus developed by the authors. Results In 97 eyes treated with ONCNEB, there was posterior capsular rupture in 1 eye; anterior chamber hemorrhage in 2 eyes; elevated intraocular pressure in 6 eyes; mild corneal edema in 8 eyes which subsided within 5 days. Corrected visual acuity ≥0. 5 was obtained in 78 eyes （80. 41% ） one week and 91 eyes （93.81%） three months after the operation. Corrected visual acuity was ≥ 1.0 in 66 eyes （68. 04% ） three months after the operation. Mean astigmatism one week and three months postoperatively showed not significant difference as compared with preoperative astigmatism. Conclusion The ONCNEB can solve the problem of implanting foldable IOL through a small incision. This procedure is relatively simple and safe.
