【摘要】：目的比较新型眼生物测量仪Tomey OA-2000与IOLMaster获得的白内障患者眼生物参数的差异性和一致性。方法前瞻性研究。纳入白内障术前检查者74例(74眼),分别应用Tomey OA-2000和IOL-Master进行测量,获得眼轴长度(axial length,AL)、角膜曲率(keratometry,K)、前房深度(anterior chamber depth,ACD)和角膜横径(white to white,WTW)等参数。配对t检验分析两种设备获得的眼生物参数之间的差异。Bland-Altman散点图分析两种设备获得的各生物参数之间的一致性。结果Tomey OA-2000获得的AL、平坦K(flat K,Kf)值、陡峭K(steep K,Ks)值、平均K(mean K,Km)值、中央角膜厚度(central corneal thickness,CCT)、ACD、晶状体厚度(lens thickness,LT)、瞳孔直径(pupil diameter,PD)和WTW值分别为(24.26±2.71)mm、(44.09±1.76)D、(45.01±1.73)D、(44.55±1.72)D、(518.41±34.18)μm、(3.07±0.48)mm、(4.48±0.61)mm、(4.07±0.95)mm和(11.50±0.52)mm。IOLMaster获得的AL、Kf、Ks、Km、ACD和WTW值分别为(24.33±2.69)mm、(44.21±1.74)mm、(45.15±1.76)D、(44.69±1.74)D、(3.04±0.46)mm和(11.65±0.41)mm。Tomey OA-2000和IOLMaster获得的AL、Kf、Ks、Km、ACD和WTW差值分别为(-0.07±0.10)mm(t=-5.99,P0.01)、(-0.12±0.14)mm(t=1.99,P=0.05)和(-0.14±0.32)mm(t=-3.73,P0.01)。两种设备获得的AL、Kf、Ks、Km、ACD的95%一致性界限(Lo A)其上下限最大绝对值分别为0.27 mm、0.50 D、0.53 D、0.38 D、0.30 mm,一致性较好;而WTW的95%Lo A为0.78 mm,一致性较差。结论Tomey OA-2000和IOLMaster获得的AL、K、ACD差异小,一致性好。
[Abstract]:Objective to compare the difference and consistency of eye biological parameters between Tomey OA-2000 and IOLMaster. Methods prospective study. 74 cases (74 eyes) of cataract were examined before cataract. The axial length (axial length,AL), corneal curvature (keratometry,K), anterior chamber depth (anterior chamber depth,ACD) and corneal transverse diameter (white to white,WTW) were measured by Tomey OA-2000 and IOL-Master, respectively. The difference between the eye biological parameters obtained by the two kinds of equipment was analyzed by pairing t test, and the consistency between the biological parameters obtained by the two kinds of equipment was analyzed by Bland-Altman scatter plot. Results the values of AL, flat K (flat K, K f, steep K (steep K, K s, mean K (mean K, km), central corneal thickness (central corneal thickness,CCT), ACD, lens thickness (lens thickness,LT), pupil diameter (pupil diameter,PD) and WTW were (24.26 卤2.71) mm, (44.09 卤1.76) D, (45.01 卤1.73) D, (44.55 卤1.72) D, respectively.
