A 26-year-old primary school teacher has had a red, watering right eye for four days; the left eye became red two days ago. She had a sore throat the week before. There is no itch. Visual acuity is 6/6 in each eye, the discharge is watery, there is a tender lump in front of the right ear, and fluorescein staining shows no corneal defect. Two children in her class have the same problem. She asks for antibiotic drops. Which one of the following eye preparations is most appropriate for her?
