Age-related paraxial schematic emmetropic eyes
Atchison, David A. (2009) Age-related paraxial schematic emmetropic eyes. Ophthalmic and Physiological Optics, 29(1), pp. 58-64.
Based on recent biometric data, four-surface paraxial schematic emmetropic eyes for different ages have been developed. There are three sets of schematic eyes: male, female and overall. With increase in age, the changes in the schematic eyes are decreased anterior chamber depth, increased lens thickness, decreased vitreous length, increased axial length, decreased anterior lens radius of curvature and increased lens equivalent refractive index. Gender differences are greater anterior corneal radii of curvature (0.07 mm), longer vitreous chambers (0.70 mm), longer axial length (0.70 mm) and lower lens equivalent refractive indices of male eyes (0.007) relative to female eyes. Gaussian parameters of the various schematic eyes are given.
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.
