Eye drops and tears.

He had lost his vision despite multiple surgical attempts over the years to save his sight. Darkness came out of his mouth, as he hurled foul language at me, while I tried to conduct a preoperative anesthesia interview and prepare him for yet another surgical procedure on his eyes. He was still stunned by a collective disappointment from his previous five corneal transplants that had failed. He had no functional vision in either eye and was here to face another three hours of surgery with nothing but a vague, guarded promise of improvement. There was a sliver of hope and possibility that his sight might recover from light perception to hand motion.
