Manoj is a 27 year old male with a red left eye and discharge for the last 2 days. He says his eyelashes on the left eye are stuck together in the morning. His vision is unaffected and there is no painful vision. He is a contact lens wearer and says he is careful with cleaning his contact lenses.
On examination you note conjunctival injection of his left eye and topical fluorescein identifies some corneal staining. Manoj is otherwise well in himself and apyrexial.
Based on the likely diagnosis, what is the best management option at this stage?
