Abstract

To provide adequate information that would assist surgeons in performing advanced refractive corrections, it is now essestial to address the problem of microfluctuations in the eye's aberrations due to pulse and respiration. Although the effects of fluctuations in defocus are known and well described, very little is reported on modelling the fluctuations in other types of aberrations. We propose a methodology in which the dynamics of higher order aberation components are modelled by parametric AM-FM signals. Using our modelling approach, the effects of changes in these aberrations could be predicted and studied. In particular, we model the dynamics of components related to coma and sperical aberration. We provide a validation of the proposed modelling approach using aberration data from the eyes of six subjects.

Search Google Scholar™

Citation counts are 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.
