摘 要:目的探讨切口位置在对白内障摘除效果的影响。方法选取河南省开封市尉氏县第二人民医院2016年11月至2018年1月间收治的84例白内障患者为研究对象,联合应用小切口白内障摘除术和人工晶体植入,采用随机图表法分组,对照组和观察组各为42例。对照组以颞上方角巩膜缘为手术切口,观察组手术主切口位于角巩膜缘上最大角膜屈光度子午线方位,辅助切口位于对侧180°角膜缘内。比较患者裸眼视力、手术源散光度、眼压、角膜内皮细胞计数、泪膜功能和并发症发生率。结果治疗前,对照组和观察组裸眼视力、手术源散光度、眼压、角膜内皮细胞计数和泪膜功能对比,差异无统计学意义(P>0.05)。治疗后,观察组术后裸眼视力高于对照组,手术源角膜散光低于对照组,差异有统计学意义(P<0.05);两组治疗后眼压对比,差异无统计学意义(P>0.05);观察组角膜内细胞计数高于对照组,泪液分泌试验值、主观干眼症状问卷评分低于对照组,泪膜破裂时间长于对照组,差异有统计学意义(P<0.05);两组并发症发生率对比,差异无统计学意义(P>0.05)。结论白内障手术中,设置手术主切口于巩膜缘上最大角膜屈光度子午线方位,辅助切口于对侧180°角膜源内,基本不影响患者眼压,对裸眼视力和泪膜功能有改善作用,手术源散光度下降,不增加手术并发症。Objective To investigate the effect of incision location on cataract extraction.Methods A total of 84 cataract patients treated in Weishi Second People's Hospital of Kaifeng City,Henan Province from November 2016 to January 2018 were selected as the research objects.The patients were treated with small incision cataract extraction and intraocular lens implantation,and they were divided into control group and observation group by random chart method,with 42 cases in each group.The control group used the sclcleral margin of the superior temporal angle as the surgical incision.In the observation group,the main incision was located at the meridional position of the maximum corneal diopter on the corneoscleral edge,and the auxiliary incision was located in the contralateral 180°corneal limbus.The naked eye visual acuity,surgical source scattered luminosity,intraocular pressure,corneal endothelial cell count,tear film function and incidence of complications were compared between two groups.Results There were no statistically significant differences in naked eye eyesight,surgical source scattered luminosity,intraocular pressure,corneal endothelial cell counts and tear film function between two groups before treatment(P>0.05).After treatment,the postoperative naked eye vision of the observation group was higher than the control group,and the surgical source corneal astigmatism was lower than that of the control group,showing statistically significant differences(P<0.05).There was no significant difference between two groups in the intraocular pressure after treatment(P>0.05).The corneal cell count in the observation group was higher than that in the control group,the tear secretion test value and the subjective dry eye symptom questionnaire score were lower than the control group,and the time of tear film rupture was higher than that in the control group,which were statistically significant(P<0.05).There was no significant difference in the incidence of complications between the two groups(P>0.05).Conclusion In cataract
