Simple measurement of oxygen transmissibility

Efron, Nathan & Brennan, Noel A. (1985) Simple measurement of oxygen transmissibility. Australian Journal of Optometry, 68(1), pp. 27-35.



This paper describes a simple, in-office procedure for measuring the oxygen transmissibility (DK/L) of hydrogel contact lenses. The procedure involves measuring lens thickness with an electrical micrometer and lens water content using a hand refractometer. A graph is provided so that the lens DK/L can be derived from these two parameters. A protocol for in-office DK/L measurement is presented and the application of this procedure to patient management is discussed.

Impact and interest:

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.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
