Check Your Medicine Cabinet: Consumer Knowledge of Contact Lens Solution Recall

CDC continues to receive reports from ophthalmologists that cases of Acanthamoeba keratitis, a potentially blinding infection, are occurring in the United States.

Multiple cases of infection caused by Acanthamoeba have occurred since May 26, 2007, the day the FDA announced the outbreak and the manufacturer issued a recall of the implicated multipurpose contact lens solution. The contact lens user in at least four of these cases continued to use AMO Complete® MoisturePlus™ multi-purpose contact lens solution and subsequently developed symptoms after the recall.

CDC has also learned during the interview stage of its investigation of the outbreak that many contact lens users do not know that AMO Complete® MoisturePlus™ multi-purpose contact lens solution has been recalled from the market because of its association with Acanthamoeba keratitis.

Healthy contact lens users from across the U.S. were interviewed by CDC as part of the ongoing investigation. They were asked if they had heard of a recalled contact lens solution and, if so, could they identify the name of that solution. Among the 151 people interviewed:

  • 52.3% (79/151) were not aware of the recall
  • Among those who were aware of the recall, only 26.8% (19/72) could correctly name the recalled product
  • Of 15 people who reported using AMO Complete® MoisturePlus™ multi-purpose contact lens solution in April 2007, 80% (12/15) were still unaware of the recall

While FDA moved swiftly and worked with the manufacturer to enact this recall, millions of bottles of the solution, purchased prior to the recall, might still be in the homes of contact lens wearers. We are concerned that this lack of awareness among the general public -- as well as eye care providers -- is leading to continued use of the product by those who had purchased it prior to the recall. (It is often sold in bulk packaging at warehouse stores and bottles have a long expiration date).

Help is being sought to get the word out:
