    $\begingroup$ did you try simply using the Mapping node between the cross product and the ramp and change the X, Y or Z scale? $\endgroup$ – Bruno Jan 5 '20 at 23:02

You currently have a node setup for one object to make the iris and the pupil. You would need to have just the iris as the background, and then another object parented to it to be the pupil. It would look like an eye, not two objects.
