【摘要】：目的比较矢量分解验光法和常规主觉验光法在不同程度散光下的应用。方法共纳入143名被检者的143只右眼,根据散光度数0~1.50 D和散光度数1.50~3.00 D分为低散光组和高散光组,被检者先后接受两名视光医师的使用矢量分解验光法和常规主觉验光法获取验光数据,比较等效球镜M分量、J0分量、J45分量以及验光时长的差异。结果高、低散光组间的年龄、性别、M分量、J45分量和常规主觉验光耗时差异均没有统计学意义(均为P0.05),两组间的常规主觉J0和矢量验光J0差异均有统计学意义(均为P=0.00)。低散光组中,分别使用常规主觉验光和矢量验光法所测得的M、J0和J45一致性较好,差值绝对值的平均值分别为0.04 D、0.02 D和0.02 D,一致性界限范围内,常规主觉验光和矢量验光的差值绝对值最大分别为0.37 D、0.13 D和0.17 D,且验光时长差异无统计学意义(P=0.72)。高散光组中,分别使用常规主觉验光和矢量验光法所测得的M、J0和J45一致性较差,差值绝对值的平均值分别为0.43 D、0.21 D和0.00 D,一致性界限范围内,常规主觉和矢量验光的差值绝对值最大分别为0.75 D、0.50 D和0.30 D,且验光时长差异有统计学意义(P=0.00),矢量验光法耗时较长。结论目前的矢量分解验光法只在针对较低的散光时有较好的表现,需要对其进一步完善,使其能较好地应用于临床。
[Abstract]:Objective to compare the application of vector decomposition optometry and routine principal optometry in different degrees of astigmatism. Methods 143 right eyes of 143 subjects were divided into low astigmatism group and high astigmatism group according to the astigmatism 0 ~ 1.50D and astigmatism 1.50 ~ 3.00D, respectively. The two optometrists used vector decomposition optometry and routine principal optometry to obtain the optometry data. The differences of M component, J0 component, J45 component and optometry duration of the equivalent spherical mirror were compared. Results there was no significant difference in age, sex, M component, J45 component and routine principal optometry time between high and low astigmatism groups (P0.05). There were significant differences between the two groups in routine principal perception J 0 and vector optometry J 0 (all P 0 0.00). In the low astigmatism group, the average values of MnJ 0 and J 45 measured by conventional principal optometry and vector optometry were 0.04 D 0.02 D and 0.02 D respectively, and the average values of the absolute values were 0.04 DX 0.02 D and 0.02 D, respectively. The absolute values of the difference between conventional principal optometry and vector optometry were 0.37 DX 0.13 D and 0.17 D respectively, and there was no significant difference in optometry duration (P0. 72). In the high astigmatism group, the consistency of MnJ 0 and J 45 measured by routine principal optometry and vector optometry was poor. The average absolute value of the difference was 0.43 DX 0.21 D and 0.00 D, respectively. The absolute values of the difference between conventional principal perception and vector optometry were 0.75 DX 0.50 D and 0.30 D respectively, and the difference of optometry time was statistically significant (P0. 00). Vector optometry took a long time. Conclusion the current vector decomposition optometry has good performance only for low astigmatism and needs to be further improved so that it can be used in clinical practice.
