Relationship between corneal thickness and level of myopia

A retrospective study of 533 eyes, which underwent complete pre-operative evaluation for refractive surgery, was done. Regression Analysis was performed to find the correlation between corneal thickness and level of myopia and between corneal thickness and corneal curvature. There was statistically significant correlation between corneal thickness and level of myopia (p = 0.039) and also in corneal thickness and corneal curvature (p = 0.04). No clinical correlation was demonstrated (R² = 0.014 and R² = 0.0153, respectively). There was no clinical correlation between corneal thickness and level of myopia and also between corneal thickness and corneal curvature.
