Hydration changes of Acuvue(TM) disposable contact lenses during disinfection

Harris, Michael G., Brennan, Noel A., Lowe, Russell, & Efron, Nathan (1989) Hydration changes of Acuvue(TM) disposable contact lenses during disinfection. Clinical and Experimental Optometry, 72(5), pp. 159-162.


To model hydrogel lens parameter changes during disinfection, the water content of 24 new AcuvueTM disposable lenses was measured with a contact lens refractometer prior to disinfection and at various intervals during the course of disinfection/neutralisation. The disinfection systems investigated were: a two-step hydrogen peroxide system (using three alternative disinfection/neutralisation cycles), a one-step hydrogen peroxide system, a preservative-based chemical system and heat disinfection. Hydrogen peroxide disinfection resulted in mean endpoint decreases in lens water content ranging from 2.1 per cent to 6.7 per cent, while the other systems resulted in changes of water content of less than 1.0 per cent. This information may assist contact lens practitioners in advising on the appropriate choice of disinfection systems to be used with daily wear of AcuvueTM lenses.

Search Google Scholar™

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.
