超声乳化白内障摘除术与手法碎核小切口白内障摘除术对硬核性白内障的治疗效果

Clinical study of phacoemulsification and manual small incision cataract surgery in the treatment of hard nuclear cataract

目的:比较超声乳化白内障摘除术与手法碎核小切口白内障摘除术对硬核性白内障的治疗效果。方法:选择进行诊治的硬核性白内障患者182例,随机分为观察组和对照组各91例;对照组采用超声乳化白内障摘除术治疗,观察组采用手法碎核小切口白内障摘除术治疗,比较两组患者治疗前后的角膜散光及术中前房出血、后囊膜破裂和虹膜损伤、术后炎症反应和角膜水肿等并发症发生率。结果:观察组于术后1 d和术后1周的角膜散光高于对照组(P<0.05),术后1个月和术后3个月两组的角膜散光相比较差异无统计学意义(P>0.05);观察组术中后囊膜破裂以及术后角膜水肿的发生率低于对照组(P<0.05)。结论:手法碎核小切口白内障囊外摘除与超声乳化白内障摘除对硬核白内障的术后效果相近,但小切口白内障囊外摘除的术中和术后并发症少,更为安全可靠。

Objective： To compare the clinical effects of pbacoemulsification and manual small incision cataract surgery in the treatment of hard nuclear cataract. Methods：182 cases of patients with hard nucleus cataract were salected and randomly divided into two groups, 91 cases in each group. The control group was treated with phacoemulsificatian, and the observation group was treated with manual small incision cataract surgery. Corneal astigmatism was compared between the two groups before and after treatment. The incidence of complications such as intraoperative hyphema, posterior capsule rupture, iris injury, postoperative inflammatory response and corneal edema were observed. Results：The astigmatism of the observation group was obviously higher than that of the control group at 1 day and 1 week after surgery （ P 〈 0.05 ）. There was no significant difference in corneal astigmatism between the two groups at 1 month and 3 months after surgery （ P 〉 0.05）. The posteri- or capsular rupture during surgery and the incidence of postoperative corneal edema after surgery in the observation group were significantly lower than those in the control group （ P 〈0.05）. Conclusion： The effect of manual small incision cataract surgery and phacoemulsification on cataract extraction was similar. But the manual small incision cataract surgery has less intraoporative and postoperative complications, which is more safe and reliable.
