摘要
目的探析白内障超声乳化手术中采用角膜最大子午线切口联合角膜缘松解切开术(LRI)的价值。方法选择2022年1月至2023年12月在南通市第三人民医院眼科接受治疗的符合筛选条件的100例白内障超声乳化手术治疗患者,依据随机数字表法对其均分2组,各50例。对照组予以常规角膜切口+散光型人工晶体治疗,观察组予以角膜最大子午线切口联合LRI+非球面人工晶体治疗。对两组术前、术后1周、1个月、6个月裸眼视力、最佳矫正视力、残余角膜散光值、周边角膜厚度及并发症发生率的比较。结果术后1个月,观察组眼压、眼部VAS评分低于对照组(P<0.05);观察组患者术后1周、1个月、6个月裸眼视力、最佳矫正视力高于对照组(P<0.05);后1周、1个月、3个月、6个月观察组残余角膜散光值、周边角膜厚度高于对照组(P<0.05)。观察组并发症发生率较对照组低,组间差异具有统计学意义(P<0.05)。结论角膜最大子午线切口联合LRI应用在白内障超声乳化手术低度数散光患者中效果明显,患者裸眼视力和散光情况明显改善,还可预防其发生并发症,临床上可借鉴及推广。
Objective To investigate the value of maximum meridional incision combined with limbus relaxing incision(LRI)in cataract phacoemulsification surgery.Methods 100 cataract phacoemulsification patients who received treatment in the Ophthalmology Department of the Third People's Hospital of Nantong from January 2022 to December 2023 were selected and evenly divided into 2 groups with 50 cases each according to random number table method.The control group was treated with conventional corneal incision+astigmatism intraocular lens,and the observation group was treated with maximum meridian incision combined with LRI+aspherical intraocular lens.Naked eye visual acuity,best corrected visual acuity,residual corneal astigmatism,peripheral corneal thickness and complication rate were compared between the two groups before surgery,1 week,1 month and 6 months after surgery.Results 1 month after operation,the IOP and VAS scores of observation group were lower than the control group(P<0.05).The observation group had higher naked eye visual acuity and best corrected visual acuity at 1 week,1 month and 6 months after surgery than the control group(P<0.05).The residual astigmatism value and peripheral corneal thickness in the observation group were higher than the control group at 1 week,1 month,3 months and 6 months after surgery(P<0.05).The incidence of complications in the observation group was lower than the control group,the intergroup differences are statistically significant.(P<0.05).Conclusion The maximum meridian incision of the cornea combined with LRI has an obvious effect in cataract phacoemulsification surgery for patients with low-degree astigmatism.The naked eye vision and astigmatism of patients are significantly improved,and complications can be prevented,which can be referenced and promoted in clinical practice.
