Abstract
An equivalent oxygen technique was used to measure the level of oxygen beneath one daily wear lens (HEMA) and two extended wear lenses (Permalens and Gelflex 75) under the closed lid of the in vivo human eye. The cornea responded as if it was in an anoxic environment with the HEMA lens, whereas the extended wear lenses resulted in responses just beneath the level of the Mandell-Farrell limit. These findings are compared with model predictions, and their physiological consequences are discussed.
Citations:
Citation countsare 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.
