A comparison of the efficacy of four units for the physical disinfection of contact lenses
Coulson, John, Shuley, Vicki L., & Collins, Michael J. (1994) A comparison of the efficacy of four units for the physical disinfection of contact lenses. Clinical and Experimental Optometry, 77, pp. 105-109.
Four contact lens disinfection units were challenged with saline suspensions of Pseudomonas aeruginosa, Staphylococcus aureus, Serratia marcescens, Escherichia coli and a clinical isolate of Candida albicans. The disinfection units all relied on physical disinfection methods and included the Sonasept unit which uses ultrasound and heat, the Aquasteril unit which uses ultraviolet radiation, the Bausch and Lomb Heat unit and the OPSM Thermos flask, both of which act through moist heat. Both the Sonasept and Aquasteril units performed poorly under most circumstances, causing little reduction in the number of viable organisms and in some cases there was an increase in the number of viable organisms following a disinfection cycle. The Bausch and Lomb Heat unit and the OPSM Thermos flask killed the challenge organisms under all test conditions.
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.
