Characteristics of Corneal Biomechanics in Chinese Preschool Children With Different Refractive Status

Purpose: To investigate the characteristics of corneal biomechanics in Chinese preschool children with different refractive status. Methods: Study participants were 108 Chinese children (216 eyes) aged 4 to 6 years with a spherical equivalent refraction between −9.00 and +9.00 diopters (D). Cycloplegic refraction was measured using an autorefractor, axial length using an IOL Master (Zeiss, Oberkochen, Germany), and corneal biomechanical metrics and corneal power using an ultra-high-speed camera (Corvis ST; Oculus, Wetzlar, Germany) and Pentacam (Oculus; Menlo Park, CA). Differences in corneal biometry and biomechanical characteristics among myopia, emmetropia, and hyperopia eyes were analyzed by SPSS 17.0. Results: The spherical equivalent refraction was significantly positively correlated with the stiffness parameter at the first applanation (SP-A1, r = 0.22, P
