Over the past year, away from the glare of public scrutiny, the optical products company has quietly settled nearly 600 fungal-infection lawsuits - with dozens more individual claims yet to be resolved. The cost so far: Upward of $250 million.

More than 700 lens wearers in the United States and Asia say they were exposed to a potentially blinding infection known as Fusarium keratitis while using ReNu with MoistureLoc, a new-formula multipurpose solution for cleaning, storing and moistening soft contact lenses.

Sometimes, the damage was irreparable. Seven people in Florida, Maryland, New York, Oregon, Tennessee and West Virginia had to have an eye removed. At least 60 more Americans needed vision-saving corneal transplants.

The U.S. Centers for Disease Control and Prevention confirmed 180 cases in 35 states from June 2005 through September 2006, when the agency's dedicated surveillance stopped, according to Dr. Benjamin Park, a CDC epidemiologist. CDC continued to hear of sporadic, unconfirmed cases in the months after MoistureLoc was withdrawn, Park said.

Among out-of-court settlements reached in May was a potential bellwether case brought by Andrea Martin, a Broadway actress and comedienne whose eye was scarred. In Colorado, a corneal transplant ended a race-car driver's career. In Baltimore, a chimney-sweep business owner who lost an eye got hooked on painkillers.

The culprit, an infection so rare that most eye doctors had never seen a case, somehow eluded MoistureLoc's disinfecting defenses. The outbreak appeared first in Hong Kong in spring 2005 and reached its peak in the United States just days after MoistureLoc was removed from domestic markets in April 2006.

With some fungal lawsuits still unresolved, the prospect of Bausch & Lomb's health care nightmare being aired in court has not entirely faded - which heartens some lawyers and doctors.
