A prayer for Isaac

Please say a prayer for my nephew Isaac. He is undergoing some surgery today to correct his pupil-iris alignment in his eye. I am not sure what the correct medical term for this is. But surgery is always scary, especially so on an infant. He is just a few weeks old. Please pray that God watch over him and the doctors caring for him. Pray for a successful surgery. And please pray for Isaac's parents, Derek and Stephanee, for patience, comfort and love. Thank you.
