Background: Contact lens has a growing popularity among people with vision impairment as well as for cosmetic reasons. However, its contamination can cause microbial keratitis. This study aimed to test the effectiveness of three antimicrobial contact lens solutions against microbial keratitis and to determine the contact time and adjustments in the existing label of multipurpose solutions. Aims and Objectives: To study the antimicrobial activity of three locally available contact lens solutions against Pseudomonas aeruginosa and Staphylococcus aureus and determined their contact time. Materials and Methods: Three bottles of each contact lens solution were evaluated using a single-blind controlled experiment method. These test solutions were categorized based on their identified disinfecting ingredient. This study evaluated the antibacterial activity of three contact lens solutions against P. aeruginosa and S. aureus at different contact times of 1, 3, 6, and 12 h. Results: All samples of contact lens solutions tested showed excellent antimicrobial activity. The contact lens solution B had the highest antibacterial activity against S. aureus and P. aeruginosa with a contact time of 6 h. Conclusion: The results showed that all the contact lens solutions demonstrate antimicrobial activity even after 24 h of exposure. Contact lens solutions containing polyhexamethylene biguanid as the active agent are found to have excellent antimicrobial activity and a desirable contact time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
