A putative class action over the size of eye medicine drops dismissed by a federal judge for lack of standing has been revived by the U.S. Court of Appeals for the Third Circuit.

The class action was filed in U.S. District Court for the Eastern District of Pennsylvania and alleged that the defendant pharmaceutical companies manufactured dispensers that emitted drops that were too large and wasted medicine, causing the plaintiffs economic harm. The case was filed under numerous states’ unfair trade practice laws.
