Man suing amusement park for parasite in eye

A man has filed a negligence lawsuit against a Pittsburgh amusement park claiming he contracted an eye-eating parasite after getting splashed on a water ride.
    
Robert and Krystsina Trostle claim in their suit this week that Robert contracted the parasite while riding Raging Rapids at Kennywood Park July 2nd.
    
He claims his eye became inflamed, and he was diagnosed with acute conjunctivitis.
    
His symptoms worsened, and on July 14th, was diagnosed with microsporidia keratitis and later endured a painful surgery that wasn't able to completely remove the parasite.
