目的:探讨应用晶状体调位钩劈核,在硬核白内障小切口非超声乳化并人工晶状体植入术的治疗效果。方法:对128例128眼白内障患者,采用角膜缘后2mm做直线巩膜隧道切口,开罐式截囊,充分水分离使晶状体核浮至前房,以注水晶状体圈匙进入核下方并向上托住核,晶状体调位钩进入前房至核前面,从核中央两手缓缓用力,将核劈为两半分别托出,并植入人工晶状体。结果:术后视力恢复快,128例术后第1d裸眼视力≥0.5者84眼(65.6%);术后1wk裸眼视力≥0.8者113眼(88.3%)。术后无严重并发症。结论:此方法视力恢复快,疗效好。无需特殊器械,设备便易,操作简便,安全、有效、经济,适用于基层医院和大规模的复明行动。

AIM:To investigate the therapeutic efficacy of lens pitch hook chop on small incision hard nuclear cataract phacoemulsification and intraocular lens implantation.METHODS:One hundred and twenty-eight patients 128 eyes underwent 2mm straight limbal scleral tunnel incision,open capsulotomy,the lens was separated to the anterior chamber,the core was held with lens ring,the lens hook was put into the lens anterior surface,and the central nuclear was chopped slowly,and split ted into two part.After that,the intraocular lens was implanted.RESULTS:The vision of all the patients was recovered quickly.In 84 eyes(65.6%) of 128 patients the uncorrected visual acuity was more than 0.5 in postoperative day 1;113 eyes(88.3%) of 128 patients the uncorrected visual acuity was more than 0.8 in postoperative week 1.No serious complications happened postoperatively.CONCLUSION:This method has a good vision recovery and curative effect without special equipment.The equipment is easy,simple,safe,effective,economic and suitable for base hospitals and large-scale light action.
