【摘要】：目的比較矢量分解驗光法和常規(guī)主覺驗光法在不同程度散光下的應(yīng)用。方法共納入143名被檢者的143只右眼,根據(jù)散光度數(shù)0~1.50 D和散光度數(shù)1.50~3.00 D分為低散光組和高散光組,被檢者先后接受兩名視光醫(yī)師的使用矢量分解驗光法和常規(guī)主覺驗光法獲取驗光數(shù)據(jù),比較等效球鏡M分量、J0分量、J45分量以及驗光時長的差異。結(jié)果高、低散光組間的年齡、性別、M分量、J45分量和常規(guī)主覺驗光耗時差異均沒有統(tǒng)計學(xué)意義(均為P0.05),兩組間的常規(guī)主覺J0和矢量驗光J0差異均有統(tǒng)計學(xué)意義(均為P=0.00)。低散光組中,分別使用常規(guī)主覺驗光和矢量驗光法所測得的M、J0和J45一致性較好,差值絕對值的平均值分別為0.04 D、0.02 D和0.02 D,一致性界限范圍內(nèi),常規(guī)主覺驗光和矢量驗光的差值絕對值最大分別為0.37 D、0.13 D和0.17 D,且驗光時長差異無統(tǒng)計學(xué)意義(P=0.72)。高散光組中,分別使用常規(guī)主覺驗光和矢量驗光法所測得的M、J0和J45一致性較差,差值絕對值的平均值分別為0.43 D、0.21 D和0.00 D,一致性界限范圍內(nèi),常規(guī)主覺和矢量驗光的差值絕對值最大分別為0.75 D、0.50 D和0.30 D,且驗光時長差異有統(tǒng)計學(xué)意義(P=0.00),矢量驗光法耗時較長。結(jié)論目前的矢量分解驗光法只在針對較低的散光時有較好的表現(xiàn),需要對其進一步完善,使其能較好地應(yīng)用于臨床。
[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.
