Rigid lenses: the pump is still alive and well
|PDF (928kB) |
With the continuing advancement of rigid gas permeable lenses, not much is heard about the traditional tear pump anymore (the bulk flow movment of tears and gases driven by lid action on the lens). The decline of edema with increasing Dk's has markedly reduced the fitters dependance on this mechanism as the sole source of corneal oxygen, yet, have the pumps benefits entirely disappeared What portion of the corneas oxygen may still be derived by this mechanical (pump) means, and what other benefits do rigid lens sytems accrue through such bulk-flow exchange.
Impact and interest:
Citation countsare sourced monthly fromand 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.
