陡峭轴切口联合对侧角膜缘松解术矫正白内障合并角膜散光患者的疗效

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...

Efficacy of the steep-axis incision in combination with the contralateral limbal relaxing incision on the cataract accompanied by corneal astigmatism

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 patients 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 corneal 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±0.16 1 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±0.09 1 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 differences 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 limbal relaxing incision can effectively improve the cataract combined with corneal astigmatism, enabling patients to achieve better visual quality after surgery.
