New Patent for an Antimicrobial Technology for CLs

Quick-Med Technologies, Inc., has been awarded an eighth U.S. patent for its non-leaching Nimbus antimicrobial technology for contact lenses. The patent (No. 8,227,017) covers the method of post-treating Nimbus contact lens and other Nibus surfaces to enhance antimicrobial efficacy and increase biofilm resistance. By introducing a citrate solution to a surface to which a Nimbus polymer has been non-leachably bound, the bactericidal performance reportedly is improved significantly. For example, a surface treated to achieve a 99% efficacy vs. the highly virulent Pseudomonas aeruginosa would be elevated to a level above 99.99%.
