Antimicrobial contact lenses and lens cases: a review.

Antimicrobial agents are being examined with the aim of developing antimicrobial contact lenses and new forms of antimicrobial lens cases. It is hoped that these developments will result in reduced contact lens-related microbial adverse events. In this review, we assess aspects of various antimicrobial strategies, such as cationic metals and peptides, selenium, quorum sensing inhibitors, and various biocidal and non-cidal agents. We highlight the historical challenges, the current scenario of this field, and recommendations for future antimicrobial strategies.
