Hi, No, visual info from the left visual field goes (ultimately)only to the primary visual cortex in the right hemisphere and vice versa. Info does "crossover" at the optic chiasm but here it's actually combining the info received from the left and right halves of each eyeball. Each hemisphere in the split-brain is functionally cut off from communicating its information to the other.
