摘　　要：目的比较Keratron角膜超声测厚仪与Pentacam测量内蒙古地区屈光不正患者中央角膜厚度的差异,为内蒙古地区屈光不正患者角膜生物力学相关参数分析提供参考,为准分子手术安全性提供依据。方法随机抽取2015年3月~2016年11月在内蒙古医科大学附属医院近视眼激光治疗中心就诊的屈光不正患者140例,其中蒙古族70例(137眼),汉族70例(140眼)。应用Pentacam和Keratron角膜超声测厚仪测量内蒙古地区蒙古族及汉族屈光不正患者中央角膜厚度,并对测量结果进行数据分析。结果 Keratron角膜超声测厚仪所测蒙古族患者的中央角膜厚度为(549.02±33.55)μm,汉族屈光不正患者的中央角膜厚度为(575.92±37.19)μm;Pentacam所测蒙古族屈光不正患者的中央角膜厚度为(538.34±32.61)μm,汉族屈光不正患者的中央角膜厚度为(557.75±31.99)μm。同一仪器测量不同民族中央角膜厚度比较,同一民族不同仪器中央角膜厚度比较,差异均有高度统计学意义(P <0.01)。结论 Pentacam测量中央角膜厚度较Keratron角膜超声测厚仪薄,研究对象中蒙古族屈光不正患者中央角膜厚度较汉族患者薄。Objective To compare the difference in central corneal thickness measurement of patients with refractive error in Inner Mongolia Region performed with Keratron corneal ultrasound thickness gauge and Pentacam, and provide reference for the analysis of corneal biomechanical parameters and basis for the safety of excimer laser surgery. Methods From March 2015 to November 2016, 140 patients with refractive error were randomly selected from the Myopia Laser Treatment Center of the Affiliated Hospital of Inner Mongolia Medical University, including 70 Mongolian(137 eyes)and 70 Han(140 eyes) patients. Pentacam and Keratron corneal ultrasound thickness gauge were used to measure the central corneal thickness of Mongolian and Han patients with refractive error in Inner Mongolia Region, and the data of the measurement results were analyzed. Results The central corneal thickness of Mongolians patients was(549.02±33.55)μm,that of Han patients was(575.92±37.19)μm measured with Keratron, the central corneal thickness of Mongolians patients was(538.34±32.61)μm, that of Han patients was(557.75±31.99)μm measured with Pentacam, there were high statistically significant differences in central corneal thickness for the different nationalities measured with same equipment and for the same nationality measured with different equipment(P < 0.01). Conclusion The thickness of the central cornea measured by Pentacam was thinner than that of Keratron corneal ultrasound thickness gauge, and the thickness of the central cornea of the Mongolian patients in the study objects is thinner than that of the Han patients.
