文摘目的研究CASIA2优化的NK和KS公式预测ICL(V4c)拱高与实际拱高的一致性。设计诊断技术评价。研究对象合肥爱尔眼科医院行ICL植入手术患者68例(68眼)。方法应用Nomogram在线公式计算68眼ICL型号,根据在线公式推荐结果分为12.1 mm、12.6 mm、13.2 mm ICL三组,再采用CASIA2测量以上三种型号组术后1天实际拱高(V1d12.1、V1d12.6、V1d13.2)、术后1个月实际拱高(V1m12.1、V1m12.6、V1m13.2),分别计算与CASIA2术前应用NK、KS公式预测拱高值的差异性、相关性和一致性,以及CASIA2内置的NK、KS公式术前推荐的ICL(V4c)型号与在线公式推荐的ICL(V4c)型号之间的符合率。主要指标实际拱高与公式预测拱高的相关性和一致性。结果全部术眼(68眼)术后1天实际拱高为(528.8±176.9)μm,术后1个月有所降低,为(476.8±161.2)μm。NK公式预测拱高为(656.2±204.5)μm,KS公式为(707.1±173.8)μm。Nomogram在线公式与NK公式之间总符合率为55.88%,与KS公式总符合率为42.65%。3种型号ICL(V4c)组术后1天实际拱高(V1d12.1、V1d12.6、V1d13.2)和1个月的实际拱高(V1m12.1、V1m12.6、V1m13.2)分别与NK公式预测拱高(VNK)、KS公式预测拱高(VKS)之间比较,除了V1d12.1组与VKS组拱高差异无统计学意义(t=-2.056,P=0.079)外,其余各型号组实际拱高均低于NK公式和KS公式预测的拱高(P均<0.05)。NK公式、KS公式的预测拱高与V1d均呈线性关系(Y=0.4728*X+218.6,Y=0.5450*X+143.4);与V1m也均呈线性关系(Y=0.3985*X+215.3,Y=0.4604*X+151.2)。68例患者术后V1d与NK公式、KS公式预测的拱高之间组内相关系数(ICC)分别为0.541、0.536,克隆巴赫系数分别为0.702、0.700;术后V1m与NK公式、KS公式预测拱高之间ICC分别为0.492、0.495,克隆巴赫系数分别为0.659、0.662。Bland-Altman分析V1d与NK公式、KS公式预测的拱高之间95%LoA分别为-486.5~231.7μm、-509.6~153.0μm,V1m与NK公式、KS公式预测的拱高之间95%LoA分别为-543.4~184.5μm、-560.6~99.86μm。�
