Abstract: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.
