Abstract Purpose : The purpose of this study is to compare corneal curvature, corneal topography, and non-surgical in refraction correction surgery to determine the difference in corneal curvature and shape between the two groups. Methods : The subjects of this study were 30 persons (60 eyes) who underwent refractive surgery and 30 non-surgery persons (60 eyes) who had no systemic or eye disease over the age of 20. The research method measured refractive error and corneal curvature in two groups using an autorefractor-keratometer, measured curvature by area of the cornea using corneal topography, and compared refractive surgery eyes and non-surgery eyes. Results : In area-specific corneal curvature, the plan for refractive surgery was 8.48±1.05 mm in area A (0~1.5 mm), 8.49±1.58 mm in area B (1.5~4.5 mm), 8.19±1.87 mm in area C (4.5~7.5 mm), and 7.93±2.87 mm in area D (7.5~10.0 mm). In non-surgery procedures, the corneal curvature by area was 7.65±0.82 mm in area A, 7.77±1.56 mm in area B, 7.70±2.27 mm in area C, and 7.88±3.42 mm in area D. Conclusion : A side effect of refractive surgery, it is believed that it can be used as data to understand the shape of the cornea while using an Autorefractor-keratometer and a corneal topography as prior tests. Key words : Corneal topography, Keratometer, Refractive surgery
