Higher-Order Aberrations and Anisometropia [PDF]
Current Eye Research, 2012 Myopia incidence is increasing around the world. Myopization is considered to be caused by a variety of factors. One consideration is whether higher-order aberrations (HOA) influence myopization. More knowledge of optics in anisometropic eyes might give further insight into the development of refractive error.To analyze the possible influence of HOA on

Analysis of Higher-Order Aberrations in a Large Clinical Population [PDF]
Investigative Opthalmology & Visual Science, 2012 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.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 ...

Higher order aberrations across the horizontal visual field
Journal of Biomedical Optics, 2006 The relationship between higher order aberrations and position in the horizontal visual field is investigated in normal and refractive corneal surgery subjects. Individual aberration coefficients are obtained from two studies using five untreated subjects and two myopic subjects following conventional laser assisted in situ keratomileusis (LASIK ...

Higher-order aberrations of the entire eye.
, 2022 Data of 62 eyes in 62 patients are shown using violin plots. Wavefront aberrations of the entire eye measured by a retinoscopic aberrometry are decomposed by Zernike polynomials for a 3-mm pupil diameter.
