Soft contact lenses and corneal topography
We investigated the effect of 3 months of daily soft contact lenswear on corneal topography. Thirty young myopic subjects who had not previously worn contact lenses were fitted with hydroxyethyl methacrylate (HEMA) soft lenses. Corneal topography was measured in each eye before and after the 3-month period using a videokeratoscope, the Topographic Modeling System (TMS). For each TMS image, we recorded the local radius of curvature at points approximately 1, 2, 3, and 4 mm along the four principal meridians. Following 3 months of soft lens wear, there was a significant steepening of the cornea in all meridians. This steepening was most pronounced in the peripheral cornea, averaging 0.09 ± 0.13 mm (i.e., about 0.50 ± 0.75 D) at 4 mm from the center of the cornea.

Citation countsare sourced monthly fromand 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.
