摘　　要：目的观察白内障患者行陡峭轴切口联合对侧角膜缘松解术后角膜散光和视力的变化。方法选取2020年1月至12月在蚌埠医学院第一附属医院眼科就诊的年龄相关性白内障合并角膜散光(>1.50 D)患者29例(30眼)为研究对象,所有患者均行陡峭轴切口联合对侧角膜缘松解术,观察术前及术后1周、1个月、3个月患者的裸眼视力(UCVA)、最佳矫正视力(BCVA)及角膜散光情况,并进行统计学分析。结果患眼术前角膜散光为(2.16±0.65)D,术后1周、1个月、3个月角膜散光分别为(0.97±0.46)D、(0.84±0.49)D、(0.87±0.47)D;术后各时间点患眼角膜散光均较术前明显降低(均为P<0.05);术后各时间点间两两相比,患眼角膜散光差异均无统计学意义(均为P>0.05)。术前UCVA为0.11±0.08,术后1周、1个月、3个月分别为0.56±0.18、0.71±0.16、0.73±0.16。术前BCVA为0.18±0.11,术后1周、1个月、3个月分别为0.67±0.15、0.82±0.11、0.83±0.09。术后各时间点患眼UCVA及BCVA均较术前明显提高(均为P<0.05);术后1周与术后1个月、3个月患眼UCVA及BCVA相比,差异均有统计学意义(均为P<0.05);术后1个月与术后3个月的UCVA及BCVA相比差异无统计学意义(P>0.05)。术后1个月UCVA≥0.6的患眼占90.0%。结论陡峭轴切口联合对侧角膜缘松解术能够有效矫正白内障合并角膜散光,使患者获得更佳的术后视觉质量。Objective To observe the changes in corneal astigmatism and vision of cataract patients after the steep⁃axis incision in combination with the limbal relaxing incision on the opposite side.Methods Totally 29 patients(30 eyes)with age⁃related cataracts and corneal astigmatism(>1.50 D)who visited the Ophthalmology Department of the First Affiliated Hospital of Bengbu Medical College from January to December 2020 were selected as the subjects.All pa⁃tients received the steep⁃axis incision in combination with the limbal relaxing incision on the opposite side.The uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA),and corneal astigmatism of patients before surgery and 1 week,1 month,and 3 months after surgery were observed.Meanwhile,a statistical analysis was conducted.Results Corneal astigmatism before surgery was(2.16±0.65)D.The corneal astigmatism was(0.97±0.46)D,(0.84±0.49)D,(0.87±0.47)D 1 week,1 month and 3 months after surgery,respectively.Corneal astigmatism significantly decreased at each time point after surgery(all P<0.05).In pairwise comparison,there was no statistically significant difference in cor⁃neal astigmatism at each time after surgery(all P>0.05).The UCVA was 0.11±0.08 before surgery and was respectively 0.56±0.18,0.71±0.16 and 0.73±0.161 week,1 month and 3 months after surgery.The BCVA was 0.18±0.11 before surgery and was respectively 0.67±0.15,0.82±0.11 and 0.83±0.091 week,1 month and 3 months after surgery.UCVA and BCVA significantly increased at each time point after surgery(all P<0.05).There were statistically significant differ⁃ences in UCVA and BCVA of the affected eyes between 1 week after surgery and 1 month and 3 months after surgery(all P<0.05).There was no statistically significant difference in UCVA and BCVA of the affected eyes between 1 month and 3 months after surgery(all P>0.05).The affected eyes with UCVA≥0.6 were founded in 90.0%of patients 1 month after surgery.Conclusion The steep⁃axis incision in combination with the contralateral limb
