A U.S. agency and eye doctors reportedly agree the ReNu With Moisture Loc contact lens solution alone was responsible for an eye infection outbreak this year.
But the research led by Dr. Douglas Chang, a fungal disease specialist at the Centers for Disease Control, said it was not clear how the solution made by Bausch & Lomb caused the problem, reports The New York Times. The findings are to be published in The Journal of the American Medical Association.
In an accompanying commentary in JAMA, two academic researchers urged more study to determine the safety of various brands of "multipurpose" lens care solutions, the report said.
On Moisture Loc, Bausch & Lomb had cited as a major factor for the outbreak customer failure to properly clean their lenses and regularly replace the storage solution, the Times reported.
Bausch & Lomb withdrew Moisture Loc from U.S. markets in April and later announced a worldwide recall. The latest study said the number of confirmed new infection cases has slowed to a trickle since the recall, the report said.
It also found no evidence of unusual risks with ReNu MultiPlus, which Bausch is using as a replacement.
