Seeing neurologist, had ct scan, seen ophthalmologist to rule out serious conditions. any suggestions to help reduce lingering eye pain after migraine?

Oxygen : Oxygen helps cluster headaches if that is what u have.

This could help: With migraine (if it was in fact a migraine), an ounce of prevention is worth a pound of cure, as they say. For now, getting some sleep, avoiding bright lights, loud sounds, nsaids may help, but if you're a migraine sufferer i think it's worth it to try to find your triggering factors (e.g., food allergies) and then having a method to stave them off asap, rx or otherwise.

Optic nerve OCT: There is a disease called benign intra-cranial hypertension (bih) or previously known as pseudo-tumor cerebri. Oct is an ocular ct scan that many ophthalmologists have. Often bih is misdiagnosed as migraine. If your oct showed optic nerve swelling (elevation) and nasal decrease of optic nerve fibers you need to have a spinal tap by your neurologist to rule this easily treated condition out.
