Abstract

To determine the efficacy of standing wave and ultrasound devices for cleaning contact lenses, the extent of coverage of an arbitrary soilant (mascara) on the surface of a high-water and a low-water content soft lens and a rigid gas permeable lens was evaluated before and after use of the Soft MateR professional Cleaning Unit (standing wave) and the SonaseptTM Ultrasonic Contact lens Cleaner and Disinfector (ultrasound). The standing wave unit removed all the mascara, but some mascara remained following ultrasound treatment. The antimicrobial efficacy of the two units was investigated by challenge with three bacteria (S. epidermidis, P. aeruginosa, and S. marcescens) and two fungi (C. albicans and A. fumigatus). Although the viable counts of some organisms were significantly reduced, the overall data does not support the use of either device as being clinically efficacious for disinfection.

Citation countsare 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.
