Small but important correction: the chemical is injected into the retina, not the cornea.
I was thinking this was cool because if it works in the cornea, it could possibly be injected into a contact lens and achieve the same effect. But it looks like that won't work because the effect depends on the chemical being in (very) close proximity to photoreceptors in the retina.
