Ocular aberrations of human eyes

Abstract

We have modified an aberroscope technique, developed by Horvland and Howland, to investigate the influence of: 1. Refractive error and 2. Accommodation on ocular aberrations. These authors analysed drawings made by subjects of retinal shadows generated by a rectangular grid pattern mounted between crossed +5 D and -5 D cylindrical lenses and a point light source. We have developed the method further by using a fundus camera to photograph these shadow pattens. Preliminary data show that third-order- coma-like aberrations are usually the dominant foveal aberrations, and that there is a trend from positive spherical aberration torwards negative spherical aberration in some accommodating eyes that have been obseeved previously with other measurement techniques.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
