Changes in through-focus spatial visual performance with adaptive optics correction of monochromatic aberrations
Guo, Huanqing, Atchison, David A., & Birt, Benjamin J. (2008) Changes in through-focus spatial visual performance with adaptive optics correction of monochromatic aberrations. Vision Research, 48(17), pp. 1804-1811.
We determined the influence of adaptive optics correction on through-focus illiterate-E visual acuity and through-focus contrast sensitivity under monochromatic conditions. In two subjects, adaptive optics improved high and low (12 %) contrast in-focus visual acuity by 0.1 to 0.15 logMAR, but resulted in more rapid and more symmetrical deterioration in visual acuity away from in-focus. In one subject, adaptive optics improved in-focus contrast sensitivity and resulted in more symmetrical and greater loss of contrast sensitivity about the peak sensitivity because of correction of higher order aberrations. The results show that full correction of higher order aberrations may worsen spatial visual performance in the presence of some defocus.
Impact and interest:
Citation counts are sourced monthly from and 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 theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
