摘　　要：目的探讨杭州市萧山区白内障患者角膜散光分布规律,及各年龄层的分布差异。方法收集2051眼白内障患者术前角膜屈光数据。对患者角膜屈光力、散光度数和散光轴位进行统计,分析不同年龄组中的分布差异。结果角膜散光度数(0.96±0.67)D。顺规散光619眼(30.18%),逆规散光1034眼(50.41%);顺规散光≥0.75 D有357眼(17.41%),逆规散光≥0.75 D有644眼(31.40%)。各年龄组间角膜平坦轴屈光力(k1),角膜陡峭轴屈光力(k2)分布及散光度数(ast)差异均有统计学意义(P<0.05)。年龄增长与k1、k2及ast变化呈正相关(P<0.05)。结论杭州市萧山区白内障患者伴有较高的角膜散光发生率,角膜散光类型有从顺规散光向逆规散光转化的趋势。Objective To study the distribution pattern of corneal astigmatism in cataract patients in Xiaoshan area and the distribution differences among different age groups.Methods Collect corneal refractive data of 2051 cataract patients before surgery.Statistical analyss corneal refractive power,astigmatism,and astigmatism axis data of patients.Simultaneously study the distribution differences of these parameters in different age groups.Results Corneal astigmatism degree(0.96±0.67)D.619 eyes(30.18%)had regular astigmatism,and 1034 eyes(50.41%)had irregular astigmatism.357 eyes(17.41%)had regular astigmatism with a deviation of 0.75 D,while 644 eyes(31.40%)had irregular astigmatism with a deviation of 0.75 D.There were statistically significant differences in the distribution of corneal flat axis refractive power(k1),corneal steep axis refractive power(k2),and astigmatism degree(ast)among different age groups.Age growth was weakly correlated with changes in k1,k2,and ast(P<0.05).Conclusion Cataract patients in Xiaoshan area have a higher incidence of corneal astigmatism,and the type of corneal astigmatism tends to shift from regular astigmatism to irregular astigmatism.
