The aim of this study is to investigate the morphometric origins of myopia, specifically focusing on the roles of axial length and corneal curvature in the development of myopia. A retrospective analysis was conducted on individuals aged 7-18 who were newly diagnosed with myopia, with key parameters such as axial length, corneal curvature (K1 and K2), and cylindrical values measured using the MYAH Topcon device. The study found a significant positive correlation between myopia degree, axial length, and astigmatism (CYL). A strong relationship between axial length and the degree of myopia and astigmatism was identified, indicating that axial elongation plays a primary role in the progression of myopia. Additionally, sex differences were observed, with males having flatter corneas. The findings emphasize the importance of evaluating both axial length and corneal curvature in the diagnosis and management of myopia. This research provides valuable insights into the morphometric risk factors of myopia, offering a deeper understanding for personalized treatment strategies and future studies in the field.

KEY WORDS: Axial length; Corneal curvature; Keratometry; Morphometry; Myopia.
