Antipseudomonal Activity of Soft Contact Lens Solution: A Comparative Study

Since contact lens disinfection solutions come into contact with the ocular surface, they may adversely affect ocular physiology if they are inappropriately formulated. Various conditions resulting from contact lens contamination and colonization by foreign organisms are causing serious problems to contact lens users. The introduction of multipurpose solutions has helped to alleviate some of the problems associated with contact lens. These infections are often associated with contaminated contact lens solutions and improper hygienic care of contact lenses. This experience has motivated us to study these disinfection systems because of the need to keep the lenses in a perfectly hygienic condition in order to avoid infection. The purpose of this study was to evaluate the disinfection capacity of a few popularly used soft contact lens solution in our country especially against pseudomonas aeruginosa. The antibacterial effects of five soft contact lens solutions are studied.
