ObjectiveTo 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. MethodsIn 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， Orbscan and ultrasound were used to measure the preoperative CCT， and the results were analyzed using ANOVA and a t test. ResultsCCT measurements between Pentacam， Orbscan and ultrasound in Mongolian males， mongolian females， Han males， Han 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）. ConclusionCCT measurements using Pentacam 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.
