超声乳化中强轴角膜切口在白内障患者中的应用分析

Application of Strong Axis Corneal Incision in Phacoemulsification in Cataract Patients

目的:探讨超声乳化中强轴角膜切口在白内障患者中的应用效果。方法:选取2021年10月—2022年10月样本医院收治的260例白内障患者作为研究对象,所有患者均接受白内障超声乳化手术治疗,根据不同手术切口将其分为观察组(n=146,强轴角膜切口)和对照组(n=114,右上方或颞侧透明角膜切口),手术切口均为3 mm;对比两组患者术前、术后1个月、术后3个月视力恢复情况[最佳矫正视力(BCVA)]和角膜散光度情况。结果:术后1个月、术后3个月,观察组与对照组相比,BCVA较高、角膜散光度较低,差异有统计学意义(t=2.975、2.055;t=7.019、9.427;P<0.05);观察组与对照组相比,前房出血、角膜切口灼伤、后囊膜破裂、后角膜水肿并发症总发生率观察组低于对照组,差异有统计学意义(χ^(2)=4.572,P<0.05)。结论:选用强轴角膜切口作为白内障超声乳化手术的切口效果较好,有助于患者视力恢复,近期对角膜散光度的影响较小,还可降低术后并发症发生率。

Objective:To investigate the effect of phacoemulsification with strong axis corneal incision in cataract patients.Methods:260 cataract patients who were treated in the hospital from October 2021 to October 2022 were selected as the research objects.All patients were treated with phacoemulsification.According to different surgical incisions,they were divided into observation group(n=146,strong axis corneal incision)and control group(n=114,right superior or temporal clear corneal incision).The surgical incision was 3 mm.The best corrected visual acuity(BCVA)and corneal astigmatism were compared between the two groups before surgery,1 month and 3 months after surgery.Results:BCVA was higher and corneal astigmatism was lower in the observation group than that in the control group at 1 month and 3 months after operation(t=2.975,2.055;t=7.019,9.427;P<0.05).Compared with the control group,the total incidence of complications such as hyphema,corneal incision burn,posterior capsule rupture and posterior corneal edema was lower in the observation group(χ^(2)=4.572,P<0.05).Conclusion:The strong axis corneal incision is a good incision for phacoemulsification,which is helpful to the recovery of visual acuity.It has little effect on corneal astigmatism and can reduce the incidence of postoperative complications.
