Combine the crab, panko, corn, and 1-1/2 tsp. salt in a large bowl. Gently stir in the eggs. With damp hands, tightly shape the mixture into eight 3/4-inch-thick cakes and place them on a small cutting board or flat plate. Refrigerate for 10 minutes.
Meanwhile, toss the lettuce and cilantro together and arrange on four plates. Finely grate the zest and squeeze the juice from the lime into a small bowl. Stir in the sour cream, and thin with a little water to make a pourable sauce. Season to taste with salt.
Heat 2 Tbs. of the oil in a 12-inch nonstick skillet over medium heat. Add 4 crab cakes and cook, flipping once, until golden brown, about 8 minutes. Repeat with the remaining oil and crab cakes. Divide the crab cakes among the plates and serve with the sour cream.
