The relationship between central corneal thickness and dioptric power of myopic eye

Background: This study aimed to assess the relationship between central corneal thickness (CCT) and the dioptric power of myopic eyes among a selected patient population. Given the increasing prevalence of myopia, understanding biometric factors associated with refractive errors is essential.Objective: This study aims to investigate the relationship between CCT and diopteric power of the myopic eye.Methods: A cross-sectional study was conducted among 70 participants, with data collected on spherical (SPH) and cylindrical (CYL) dioptric power, CCT, and visual acuity. Statistical analysis was performed to determine correlations between these parameters.Results: The majority of participants were female (57.15%), with the most common age group being 26-30 years (45.71%). Most individuals had a CCT between 501-550 µm, with a mean CCT of 532.58±4.67 µm. The distribution of spherical power showed a predominance in the 3.00 to -5.00 D range, and cylindrical power was primarily within the 0.00 to 0.50 D range. No statistically significant correlation was found between CCT and dioptric power.Conclusion: Our study suggests that CCT is not a significant determinant of myopic refractive error. Other factors such as axial length and corneal curvature may play a more crucial role. Further research with a larger sample size and additional biometric parameters is recommended to explore the underlying mechanisms of myopia progression.
