METHODS During the first phase of the Shahroud cohort study, 6311 people of the 40-64-year-old population of Shahroud city were selected through random cluster sampling. A subsample of participa...
متن کاملOcular higher-order aberrations in a school children population.
PURPOSE The primary objective of the study was to explore the statistics of ocular higher-order aberrations in a population of primary and secondary school children. METHODS A sample of 557 children aged 10-15 years were selected from two primary and two secondary schools in Heraklion, Greece. Children were classified by age in three subgroups: group I (10.7±0.5 years), group II (12.4±0.5 yea...
متن کاملAnalysis of higher-order aberrations in a large clinical population.
PURPOSE To use a large wave-front database of a clinical population to investigate relationships between refractions and higher-order aberrations and between aberrations of right and left eyes. METHODS Third- and fourth-order aberration coefficients and higher-order root-mean-squared aberrations (HO RMS), scaled to a pupil size of 4.5-mm diameter, were analyzed in a population of approximatel...
متن کاملEvaluation of corneal higher order aberrations in normal topographic patterns
PURPOSE This study reports the characteristics of corneal higher order aberrations (HOAs) in eyes with normal topographic pattern using the Pentacam scheimpflug system. METHODS In this prospective, observational, comparative study, 165 eyes of 97 patients separated into five groups based on corneal topographic patterns were enrolled. All eyes received a comprehensive ophthalmologic examinatio...
متن کاملOcular higher-order wavefront aberrations in the Japanese adult population: the Yamagata Study (Funagata).
PURPOSE To investigate the relationship between age and ocular higher-order wavefront aberrations (HOAs) in an adult Japanese population, in addition to factors associated with HOA variations. METHODS In the Yamagata Study (Funagata) cohort, 227 adult Japanese participants (aged 37-86 years) underwent systemic and ophthalmologic examinations in 2012. Ocular, corneal, and internal HOAs were me...
