Corneal Higher-Order Aberrations in Infectious Keratitis
American Journal of Ophthalmology, 2017To characterize the corneal higher-order aberrations (HOAs) in eyes with Acanthamoeba keratitis (AK), bacterial keratitis (BK), and fungal keratitis (FK).Retrospective consecutive case series.This retrospective study includes 18 normal subjects and 63 eyes of 62 consecutive patients with corneal scarring due to AK (20 eyes), BK (35 eyes), and FK (8 ...

Corneal High-Order Aberrations in Fuchs Endothelial Corneal Dystrophy and Subclinical Corneal Edema
CorneaPurpose: High-order aberrations (HOAs) are known to be increased in corneas with Fuchs endothelial dystrophy (FECD) and are associated with visual impairment. This case series aimed to analyze whether tomographic changes in FECD affect the HOA in the early period of the disease. Methods:

Corneal biomechanics study : relationship between corneal aberration – hysteresis
Acta Ophthalmologica, 2009Abstract Purpose To determinate the relatioship between corneal aberration and a biomechanical parameter: the corneal hysteresis. Methods 122 eyes of 61 patients were included in a prospective and transversal study. Range of age was between 18 and 60 years.

Chromatic aberration of a dipteran corneal lens
Journal of Comparative Physiology ? A, 1982The longitudinal chromatic aberration (variation in the position of focus with wavelength) of corneal facet lenses of the houseflyMusca domestica is measured directly. The result is shown to agree with that calculated using the thick-lens formulas, the measured lens parameters and the dispersion of the refractive index of the lenses, measured with an ...

[Quantification of corneal aberrations with an aberration coefficient].
Klinische Monatsblatter fur Augenheilkunde, 2003Abnormal corneal surfaces in keratoconus, contact lens induced corneal distorsion or after refractive surgery are thoroughly described by Zernike polynoms. This study investigated such deviations from the healthy eye by a newly introduced aberration coefficient.300 healthy eyes were measured with videokeratometry. Corneal Zernike coefficients (grade 1.

Higher-order aberrations after corneal collagen crosslinking for keratoconus and corneal ectasia
Journal of Cataract and Refractive Surgery, 2012To determine changes in higher-order aberrations (HOAs) after corneal collagen crosslinking (CXL).Cornea and refractive surgery practice.Prospective randomized controlled clinical trial.Corneal and ocular HOAs were measured and analyzed using the Pentacam device and Ladarwave aberrometer, respectively, at baseline and 12 months after CXL.Ninety-six ...

Corneal Higher-Order Aberrations in Eyes With Corneal Scar After Traumatic Perforation
Eye & Contact Lens: Science & Clinical Practice, 2019Objectives: To evaluate corneal higher-order aberrations (HOAs) in eyes with corneal scar after traumatic perforation and their correlation with visual acuity. Methods: This retrospective consecutive case study included 40 eyes of 40 consecutive patients (mean age, 39.2±21.6 years),
