I can understand your problem and the situation. Ideally you should get nerve conduction study (NCV) and electromyography (EMG). This will give us a correct perspective of the extent of the injury and even prognosis.
At present the treatment should constitute of
a) Physical therapy which will constitute of active and passive exercises
b) Electrical stimulation
c) High doses of vitamin B1, B6, B12.
d) Massage in the direction of muscle fibers.
e) Avoidance of cold stimuli as it aggravates the stiffness, muscle edema.
For eye care you need use of tear substitutes, lubricants, and eye protection (Eyeglasses or shields). They protect the eye from injury and reduce drying by decreasing the air currents that come directly in contact with the exposed cornea.
There are some surgical options also worth trying, if the nerve recovery won't be good.
It would be better to talk to your surgeon in clear terms about the prognosis and various other options and further management. If he does not offer you anything clear and concrete, you would need a referral from your family physician.
