Bausch & Lomb Inc. is in serious trouble after an eye infection was detected in association with the use of one of its lens care products. There are complaints arising from Asia, US and Europe under pressure since authorities said its contact lens care products might be linked to a spate of serious eye infections in Asia and the United States, said a handful of cases of the infection had also been confirmed in Europe. Bausch & Lomb, based in Rochester, New York, recalled ReNu lens care products after users were diagnosed with fungal infections. Health authorities have not yet determined a root cause of the fungal infection, known as Fusarium keratitis, which can lead to blindness and potential eye loss.
