Advanced Medical Optics Company has recalled a line of its popular contact-lens solutions over concerns the product has triggered a rare but dangerous eye ailment in some users. Advanced Medical said late Friday it was issuing a global recall for its Complete MoisturePlus lens solutions because of reports that 21 users of the product since January 2005 had contracted acanthamoeba keratitis, an infection of the cornea that can lead to blindness. Complete MoisturePlus solutions are used to store and re-wet soft contact lenses.
