After efforts to improve comfort, reduce toxicity, and facilitate compliance regarding multipurpose contact lens solutions, the time has come to enhance their antimicrobial efficacy. It had been hoped that the ease of use of multipurpose solutions would enhance compliance, but noncompliance remains common, and even compliant patients have developed serious infections. In 2006 and 2007, there were voluntary recalls of 2 specific multipurpose solutions owing to their association with Fusariumand Acanthamoebacorneal infections. Since this time contact lens–associated Fusariuminfections appear to have decreased, but Acanthamoebainfections remain a serious problem. Standards for multipurpose solutions need to be modified to include cidal action against Acanthamoebacysts. Instructions for contact lens care need to include directions to resume rub-and-rinse steps and avoid exposure of contact lenses and lens cases to water.
