Take a look at Skairu's shaders.
3D Artist Skairu showcased an eye-catching demo featuring a pupil that dynamically adjusts by constricting and dilating in response to light. Although the technical details weren't provided, the effect appears to be achieved with pupil tracking and a custom Unity eye shader that allows for pupil size changes, truly impressive work.
