Evaluation of an enhanced cleaning and storage method for in-office disinfection of hydrogel contact lenses

Abstract

Even though a trial contact lens has been cleaned prior to storage, there is little guarantee that the lens storage environment is sterile (except in the case of autoclaving the lens within the storage vial). The underside of the cap is often an overlooked potential source of contamination to the system. This study evaluated the effectivity of Bausch & Lomb ReNu Multi-Purpose Solution as an in-office storage solution using an enhanced cleaning method, as well as the utility of inverting the lens vial during the disinfecting period. The results show that inversion of the vial assists in assuring a more growth free environment, yet proper cleaning of the lens and the vial stopper is vital to obtain maximum effectiveness with this in-office contact lens storage system
