Corneal thickness changes during scleral lens wear: Effect of gas permeability
The compatabillity of scleral lens wear with the physiological requirements of the cornea was assessed by measuring corneal thickness changes. Lenses made of either poly(methyl methacralate) (PMMA) (effectively non-oxygen permeable) or itaflourocon B (equalens II) material (oxygen permeability of 121 x 10-11cm2 ml O2/sec ml mmHg) were directly compared by fitting one lens type to each eye of eight subjects. The rate of corneal thickness increase was 0.98 +/- 3.33 microns/hour for gas permeable lenses and 14.84 +/- 14.93 microns/hour for PMMA lenses. this difference was statistically significant (p= 0.039)
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.
