Oxygen has been the “holy grail” of contact lens wear for over 100 years, but it is just one piece of a complex jigsaw puzzle. Clearly, high oxygen transmissibility (Dk/t) silicone hydrogel lenses meet the oxygen needs of the cornea. The Dk/t of these lenses is over 75 Dk units, which is far above that of the “best” hydrogel lenses (30 Dk units). Clinical trials have failed to reveal any hypoxic problemswith silicone hydrogel lenses. Thus, conditions such as epithelial microcysts, limbal redness, hypoxic staining, stromal neovascularisation, oedema and endothelial polymegethism do not occur with these lenses. My view is that – looking at the “big picture” – we are far better off now that we have silicone hydrogel lenses.

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.
