A judge affirmed more than $487 million in penalties and damages against Cameron-Ehlen Group, operating as Precision Lens, and its owner Paul Ehlen after a jury found they filed tens of thousands of false claims to Medicare and violated the Anti-Kickback Statute.

The ruling of Judge Wilhelmina Wright of the District of Minnesota followed a February guilty verdict that found the defendants liable for paying kickbacks to ophthalmic surgeons to influence their use of Precision Lens products in Medicare-reimbursed cataract surgeries, the Department of Justice (DOJ) announced Monday in a press release.
