Accommodation with higher-order monochromatic aberrations corrected with adaptive optics.
Higher-order monochromatic aberrations in the human eye cause a difference in the appearance of stimuli at distances nearer and farther from best focus that could serve as a signed error signal for accommodation. We explored whether higher-order monochromatic aberrations affect the accommodative response to 0.5 D step changes in vergence in experiments in which these aberrations were either pre...
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 کاملcontrast sensitivity and higher-order aberrations in myopes
purpose: to investigate the relationship between higher-order aberrations (hoas) and contrast sensitivity function (csf) in myopes. methods: in this cross-sectional study, hoas and csf were measured in myopic eyes over a 6-mm pupil. pupil diameter was measured in photopic condition. the correlation between hoas and csf was investigated using multivariate linear regression analysis. results: sev...
متن کاملHigher-Order Aberrations in Myopic Eyes
PURPOSE To evaluate the correlation between refractive error and higher-order aberrations (HOAs) in patients with myopic astigmatism. METHODS HOAs were measured using the Zywave II aberrometer over a 6 mm pupil. Correlations between HOAs and myopia, astigmatism, and age were analyzed. RESULTS One hundred and twenty-six eyes of 63 subjects with mean age of 26.4±5.9 years were studied. Mean s...
متن کاملeffect of unilateral congenital ptosis on ocular higher order aberrations in children
800x600 to analyse the effect of congenital unilateral ptosis on the ocular higher order aberrations (hoa) and to compare these eyes with normal fellow eyes this study has been performed. in this observational comparative case series, 16 eyes of 16 patients less than 15 years old with congenital unilateral upper eyelid ptosis were included. corrected distance visual acuity (cdva), corneal topog...
