摘　　要：目的:评估角膜曲率仪与电脑验光仪对准分子激光原位角膜磨镶术(LASIK)前患者角膜曲率的一致性。方法:选取2022年1-12月联勤保障部队第九六九医院就诊拟行LASIK的65例(130眼)近视患者,应用角膜曲率仪及电脑验光仪行角膜曲率测量,记录角膜曲率,水平径线上的角膜曲率(Kl)、垂直径线上的角膜曲率(K2)及平均角膜曲率[(K1+K2)/2]值。用一致性评价测量方法(Bland-Altman)分析两种仪器测量方法的一致性。结果:电脑验光仪与角膜曲率仪测得的角膜曲率无显著差异,两种仪器在测得的K1、K2以及(K1+K2)/2值呈正相关(r=0.483、0.409、0.427,P<0.05)。两种仪器测得的角膜曲率Kl、K2值及[(K1+K2)/2]值差值均数d分别为42.094D、42.919D和42.981D,差值的标准差(SD)分别为2.113D、2.157D和2.282D。95%CI分别为(46.770~37.419)、(47.148~38.691)和(47.145~38.508)。结论:电脑验光仪与角膜曲率仪有较好一致性,可相互替代使用,临床应综合考虑两种仪器的适用性,以发挥最大作用。Objective:To assess the consistency between corneal curvature instrument and computer optometry instrument for corneal curvature of patients before underwent laser-assisted in situ keratomarisis(LASIK).Methods:A total of 65 myopic patients(130 eyes)who planned to undergo LASIK at the 969th hospital of People’s Liberation Army Joint Service Support Force from January to December 2022 were selected.Corneal curvature instrument and computer optometry instrument were applied to record corneal curvature,corneal curvature on the horizontal radial line(Kl),corneal curvature on the vertical radial line(K2)and average corneal curvature[(K1+K2)/2]values.Using the method of consistency evaluation measurement(Bland Altman)to analyze the consistency between two kinds of measurement methods of instrument.Results:There was no significant difference in corneal curvature values between computer optometry instrument and corneal curvature instrument.There were positive correlations in the K1,K2 and(K1+K2)/2 between two instruments(r=0.483,0.409,0.427,P<0.05),respectively.The mean d of the differences of the measured Kl,K2 and[(K1+K2)/2]values of corneal curvature between two kinds of instruments were respectively 42.094D,42.919D and 42.981D,and the standard deviation(SD)of the differences were respectively 2.113D,2.157D and 2.282D.The 95%CI were respectively(46.770-37.419),(47.148-38.691)and(47.145-38.508).Conclusion:There is favorable consistency between computer optometry instrument and corneal curvature instrument,and they can be used by mutual substitution.The applicability of the two instruments should be comprehensively considered in clinical work,so as to play its maximum role.
