【摘要】：目的评价注水圈套器娩核法、水压娩核法和前房内劈核法三种不同娩核方式在小切口非超乳白内障手术中应用的特点和疗效。方法对327例(327眼)老年性白内障患者,随机分成三组,分别通过注水圈套器娩核法、水压娩核法和前房内劈核法完成娩核过程,观察记录娩核时间、术中并发症、术后d 1角膜内皮水肿程度及术后视力,统计学处理差异。结果娩核时间:注水圈套器娩核法平均时间45 s、水压娩核法平均时间34 s和前房内劈核法平均时间65 s,三组的平均娩核时间差异均有统计学意义(P0.05)。注水圈套器娩核法和前房内劈核法的并发症主要表现为虹膜损伤和后囊膜破裂;水压娩核法则主要表现为前房出血。统计学分析,角膜水肿0~1级者:A组与B组、B组与C组差异均有统计学意义(P0.05),A组与C组统计学处理差异无统计学意义(P0.05)。术后1 d视力:A组与C组、B组与C组差异均有统计学意义(P0.05),术后7 d视力:只有B组与C组差异有统计学意义(P0.05),术后1mo视力:三组间差异无统计学意义(P0.05)。结论水压娩核法术中并发症少,术后d 1角膜内皮水肿发生率低,更适用于Ⅳ级以下的核娩出;前房内劈核法对Ⅳ级以上核的处理优势是明显的。
[Abstract]:Objective to evaluate the characteristics and efficacy of three different methods of nucleus delivery in small incision non-supermammary cataract surgery with water injection trap delivery method, water pressure nuclear delivery method and anterior chamber nucleus splitting method. Methods 327 cases (327 eyes) of senile cataract were randomly divided into three groups. The nuclear delivery process was completed by the method of water injection trap, water pressure and nucleus splitting in anterior chamber, and the time of nucleus delivery and complications during operation were observed and recorded. The degree of corneal endothelium edema and postoperative visual acuity were significantly different on postoperative day 1. Results the mean time of nucleus delivery: the average time of nucleus delivery with water trap method was 45 s, the average time of nuclear delivery method with water pressure method was 34 s and the average time with nucleus splitting method in anterior chamber was 65 s. There was significant difference in average nuclear delivery time among the three groups (P0.05). The complications of injection trap delivery method and anterior chamber nucleus splitting method were mainly iris injury and posterior capsule rupture, while the rule of water pressure nuclear delivery was anterior chamber hemorrhage. Statistical analysis showed that there was significant difference between group A and group B and group C (P0.05). There was no significant difference between group A and group C (P0.05). The visual acuity of group A and group C were significantly higher than that of group C at 1 day after operation (P0.05). The visual acuity of group B and group C had statistical significance at 7 days after operation (P0.05). The visual acuity of postoperative 1mo: there was no significant difference among the three groups (P0.05). Conclusion the incidence of corneal endothelial edema is low on the first day after operation, and it is more suitable for nuclear delivery under grade 鈪，
