The authors performed a statistical analysis of the dependence of the total level of aberrations and the integral level of higher-order aberrations (hereafter, higher-order aberrations) depending on the type of clinical refraction and the degree of ametropia. The calculations made it possible to conclude that higher-order aberrations are characteristic of both eyes with emmetropia ("normal vision") and eyes with ametropia (myopia and hyperopia). It turned out that the total level of eye aberrations in general directly correlates with the degree of ametropia and statistically significantly increases with an increase in the degree of ametropia (spherical component of refraction). Higher-order aberrations are practically unchanged in front of eyes with emmetropia and ametropia. According to updated data, the authors found that in the eyes with weak and moderate hypermetropia, the integral level of higher-order aberrations is higher than with myopia and emmetropia, but with a slight statistically significant difference.
