【摘要】：目的比较年龄相关性白内障患者术前IOL Master、角膜地形图及Pentacam测量角膜散光各参数的差异。方法收集我院年龄相关性白内障患者56例(67眼),术前分别通过IOL Master、角膜地形图及Pentacam测量平坦子午线角膜屈光力即最小角膜曲率(flat keratometry,Kf)、陡峭子午线角膜屈光力即最大角膜曲率(steep keratometry,Ks)、平均角膜曲率(mean keratometry,Km)、散光度参数J0(cylinder at 0-degree meridian)及轴向参数J45(cylinder at 45-degree meridian);采用配对t检验对三组测量结果的差异进行比较,不同测量仪器所得的数据的相关性采用Pearson相关性分析,三种方法测量结果的一致性采用Bland-Altman分析。结果 IOL Master测量Kf、Ks、Km、J0、J45分别为(43.524±1.751)D、(44.352±1.839)D、(43.938±1.753)D、(0.059±0.455)D、(0.264±0.228)D;角膜地形图所测Kf、Ks、Km、J0、J45分别为(43.404±1.740)D、(44.290±1.843)D、(43.847±1.753)D、(0.046±0.453)D、(0.242±0.222)D;Pentacam所测Kf、Ks、Km、J0、J45分别为(43.401±1.739)D、(44.285±1.838)D、(43.843±1.751)D、(0.047±0.456)D、(0.241±0.221)D;IOL Master和角膜地形图及Pentacam的检测结果比较差异均有统计学意义(均为P0.05),角膜地形图及Pentacam检测结果比较差异无统计学意义(P0.05);Pearson相关分析显示,Kf、Ks、Km、J0、J45等5个指标在三种检查仪器检测结果之间均有高度的正相关性(均为P0.001)。Bland-Altman一致性分析说明三种仪器的检测结果具有较好的一致性。结论 IOL Master、角膜地形图及Pentacam均可以应用于年龄相关性白内障患者术前测量角膜散光的各项参数。
[Abstract]:Objective to compare the parameters of corneal astigmatism measured by IOL Master, corneal topography and Pentacam in patients with age-related cataract before operation.Methods A total of 56 patients (67 eyes) with age-related cataract in our hospital were collected. The refractive power of flat keratometry was measured by IOL Master, corneal topography and Pentacam before operation, and the corneal refractive power of steep meridian was the largest.The results of the three groups were compared by paired t test, mean keratometry, astigmatic parameter J0(cylinder at 0-degree meridian and axial parameter J45(cylinder at 45-degree meridian.The correlation of data obtained from different measuring instruments is analyzed by Pearson correlation analysis, and the consistency of measurement results by three methods is analyzed by Bland-Altman.缁撴灉 IOL Master娴嬮噺Kf,Ks,Km,J0,J45鍒嗗埆涓，
