Effect of topical anaesthesia on corneal epithelial fragility
The effect of topical anaesthetics on human corneal integrity was assessed by measurement of the alterations they cause in corneal damage threshold. The anaesthetics investigated were 1.0% Amethocaine HCl, assessed immediately after instillation and after delays of 20 min and 60 min, and 0.5% Amethocaine HCl and 0.4% Benoxinate HCl, assessed 20 min after instillation. At 20 min after instillation of 1.0% Amethocaine HCl, the corneal damage threshold was significantly decreased. At other times for this anaesthetic, and for 0.5% Amethocaine HCl and 0.4% Benoxinate HCl, the corneal damage threshold was unaltered.
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.
