Same happened with my Xperia Z and the water droplets formed totally evaporated after a week or so. My phone worked fine thereafter.
My personal advice would be to not use your phone until the water completely evaporates or you might end up damaging the camera ( and anything that would come in contact with water) at all.
Open all the ports. To remove the moisture out of your phone sooner, put it inside a container full of rice or with silica gel packets.

You have got to be patient. Do not use your phone for as long as possible and it could be worth the wait.
If the camera has been damaged already then you have no choice but to have your phone examined at service center
