£Õ£–£”° multipurpose solution°ň°®Submission of a written request to prevent acanthamoeba keratitis in MPS users

2009-12-16

MPS (multipurpose solution°ňis a soft contact lens care product(quasi drug) used to clean, rinse, disinfect, and store soft contact lenses, that has been on sale since 1996°°in Japan.

It is said that the number of patients with acanthamoeba keratitis is ncreasing rapidly, and 90 % of these patients are MPS users,in particular users who replace their contact lenses every two weeks. °°.

The diagnosis and treatment of acanthamoeba keratitis is difficult and patients may lose their sight if their conditions worsen.

On December 16th 2009, we submitted a written request to the Ministry of Health, Labor and Welfare (MHLW), Consumer Agency, and Consumer Committee to prevent acanthamoeba keratitis in MPS users.


°„Our Request Outline>

We request that the MHLW and Consumer Agency:

£Ī. Immediately warn MPS users about the risk of acanthamoeba keratitis.

£≤. Set up a MHLW survey committee to carry out a fact finding survey in order to investigate the cause of acanthamoeba keratitis in £Õ£–£” users, and to publish the results of the survey.

£≥. Establish appropriate test methods to confirm the effect of disinfection on acanthamoeba keratitis, which is required in the marketing application procedures for MPS.
