The patient's vision was affected, though not as much as one would think. Visual areas in the left hemisphere represent the righthand size of visual space, while those in the right hemisphere represent the the left part of the world. With one hemisphere totally removed, you'd think the patient would be half blind. However, Dan Guitton's lab showed that D.R. still has some residual "blindsight" and that stimuli flashed in the blind hemifield affect eye movements. I'm not sure what else, though the patient had a rather normal life: held down a job, was involved in some civic organizations, stuff like that.
