The Dk project: an interlaboratory comparison of Dk/L measurements
Holden, Brien A., Newton-Howes, Julia, Winterton, Lynn, Fatt, Irving, Hamano, Hikaru, La Hood, Donna, Brennan, Noel A., & Efron, Nathan (1990) The Dk project: an interlaboratory comparison of Dk/L measurements. Optometry and Vision Science, 67(6), pp. 476-481.
The oxygen transmissibilities (Dk/L) of a set of 48 contact lenses made from 8 different materials were measured by 4 laboratories. The L/Dk measurements from each laboratory were compared and correlated. Samples which were not masked with a fixed front surface aperture during measurement were corrected for edge effects. This paper shows that provided L/Dk is calculated for each lens using the same technique and Dk is derived using a graphical method of calculation, similar results can be obtained by all laboratories. However, the agreement was less good for materials of Dk greater than 70 x 10(-11) (cm2/s) (ml O2/ml x mm Hg).
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.
