摘　　要：目的探讨内蒙古地区蒙古族、汉族不同性别近视患者中央角膜厚度值及不同仪器测量角膜厚度（CCT）的差异。方法横断面研究。选取预行双眼准分子激光原位角膜磨镶术（LASIK）或前弹力层下激光角膜磨镶术（SBK）的近视患者260例（520眼），其中蒙古族112例，男60例，女52例；汉族148例，男82例，女66例。分别采用Pentacam、Orbscan角膜地形图系统和超声角膜测厚仪3种仪器测量中央角膜厚度值。数据采用单因素方差分析和独立样本t检验进行分析。结果不管是在蒙古族还是在汉族，是男性还是女性，Pentacam测得的CCT值比Obscan和超声测厚仪都小，差异有统计学意义（F=7．052、19．057、21．330、17．391，P〈0．01）。除了Orbscan测得的CCT值蒙古族男性较蒙古族女性小，差异有统计学意义（t=0．013，P〈0．05）外，余比较均无统计学意义。结论Pentacam测得的内蒙古地区近视眼CCT较Orbscan与超声测厚仪测量值小。Orbscan测得的蒙古族男性CCT较女性小。Objective To evaluate and compare central corneal thickness （CCT） among Mongolian and Han populations with myopia; to analyze the differences in corneal thickness measurements when using different instruments. Methods In a prospective study, measurement agreement was assessed in 520 eyes of 260 pre-LASIK and pre-SBK patients using Pentacam, Orbscan and ultrasound. There were 112 Mongolian patients （224 eyes）, in which 60 were males （120 eyes） and 52 were females （104 eyes）; and 148 Han patients （296 eyes）, in which 82 were males （164 eyes） and 66 were females （132 eyes）. Pentacam, Orbsean and ultrasound were used to measure the preoperative CCT, and the results were analyzed using ANOVA and a t test. Results CCT measurements between Pentacam, Orbsean and ultrasound in Mongolian males, mongolian females, Han males, Hart females were significantly different （F=7.052, 19.057, 21.330, 17.391, P〈0.01）. CCT measurements were compared between the different genders in the Mongolian and Han populations with the three above-mentioned instruments. There were no significant differences between any two measurements except that CCT is thinner in Mongolian males compared with Mongolian females by Obscan （t=0.013, P〈0.05）. Conclusion CCT measurements using Pentaeam were smaller than measurements obtained with Orbscan and ultrasound. Orbscan measurements of central corneal thickness in Mongolian men and women result in significantly different values.
