Fitting Zernike polynomials to ocular wavefront aberrations. Effect of the radial order on the fitting accuracy
نویسنده
چکیده
METHODS: Ocular wavefront maps were obtained from 19 normal eyes using a ShackHartmann aberrometer. The tenth Zernike order fit was considered to be the real wavefront of the eyes. Different fittings from second to ninth Zernike orders were computed and compared with the tenth order. The ratio of the root mean square (RMS) error between the different fittings and the original wavefront was calculated, and a percentage value was given. This was performed for two pupil diameters: 3 and 6 mm.

Comparison of Zernike and Fourier wavefront reconstruction algorithms in representing the corneal aberration of normal and abnormal eyes
Purpose: The goal of this study was to investigate with what accuracy the Zernike and Fourier reconstruction algorithms can describe the corneal aberration in normal and abnormal eyes. Methods: Corneal topography (Orbscan IIz) was collected on 87 normal, 27 keratoconus, 9 penetrating keratoplasty (PKP), and 20 post-LASIK symptomatic eyes. Raw topography images were converted into elevation maps...
متن کاملZernike polynomial fitting fails to represent all visually significant corneal aberrations.
PURPOSE It is assumed that wavefront error data arising from aberrometry are adequately described by a Zernike polynomial function, although this assumption has not been extensively tested. Inaccuracies in wavefront error may compromise clinical testing and refractive correction procedures. The current retrospective study correlates visual acuity with corneal wavefront error and with the residu...
متن کاملMonochromatic ocular wavefront aberrations in the awake-behaving cat
Measurement of wavefront aberrations in human eyes has become a reliable, quantitative way of assessing the optical impact of experimental and corrective ocular manipulations. Wavefront measures have also been performed in several other species, but never in cats, an animal model of choice for many ocular studies. Our goal in this study was to measure wavefront aberrations reliably in live, awa...
متن کاملAccuracy of Zernike polynomials in characterizing optical aberrations and the corneal surface of the eye.
PURPOSE Zernike polynomials have been successfully used for approximately 70 years in many different fields of optics. Nevertheless, there are some recent discussions regarding the precision and accuracy of these polynomials when applied to surfaces such as the human cornea. The main objective of this work was to investigate the absolute accuracy of Zernike polynomials of different orders when ...
متن کاملDetermining the accommodative response from wavefront aberrations.
The purpose of this study was to evaluate some of the methods used to calculate objective refractions from wavefront aberrations, to determine their applicability for accommodation research. A wavefront analyzer was used to measure the ocular aberrations of 13 emmetropes and 17 myopes at distance, and 4 near target vergences: 2, 3, 4, and 5 D. The accommodative response was calculated using the...
