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.
