Description

<p>Purpose: This study aimed to evaluate the correlation between ocular refraction and total, corneal, and internal higher-order aberrations in myopic with-the-rule astigmatism.</p><p>Methods: A total of 77 healthy young adults (mean age ± standard deviation, 21.0 ± 0.8) were participated in this study. The objective ocular refraction, coma, trefoil, and spherical aberrations in the right eye were performed three times each using the wavefront aberrometer. The correlation between objective ocular refraction and total, corneal, and internal higher-order aberrations was examined.</p><p>Results: Astigmatism was significantly correlated with internal coma and corneal spherical aberrations (internal coma: P = 0.025, corneal spherical: P = 0.010). Spherical power was not significantly correlated with the higher-order aberrations.</p><p>Conclusion: These findings suggested that with-the-rule astigmatism was correlated with internal coma and corneal spherical aberrations in healthy young adults with myopia.</p>
