Oldster has it right, absolutely nothing until they are looking better. Like he said it is going to be a PITA trying to get that soil moist again. Water very slowly until you see runoff, let it sit for 5 minutes or so and water again very slowly. What you want to do is give the water time to be absorbed by the soil because there are going to be patches in the container that are dry no matter how slowly you water it. If you give them time to absorb some of the water then the second time you water it about 5 minutes later, the soil will absorb more. The biggest thing is to make sure you water all of the pot. In other words, start at the center and work your way around the stem and out to the edges of the container. Try and get the soil moist as evenly as possible.
Best of luck! Also like Oldster said, they should be fine but you may see some leaves die off. Won't be too big a deal.
