Much needed Eye surgery for son

My son Grant is 17. He is a very polite, Straight A student, and a hard working young man, who wants to go to college to be a music director. He is in the band at Gladwin High School. He is also a student in the Students of Promise  at Mid Michigan Community College.
He needs a very important eye surgery done. He has kerataconus. It's a disease that makes the corneas bulge out. Without this procedure he will need a cornea transplant by the time he is 22. He is going blind very fast. Our insurance company is fighting us on this. For us to get the second procedure done I need 2600 up front.(**Update)  Last October he got his first surgery in his right eye. Now we need the left eye done.  Please share this with your friends, and help us get Grant tge surgery he needs...
Can you find it in your heart to help me so my son can see again... Thank you and God bless you.
*** his procedure for his left eye were t up to $9000. Now we're have to come up with that much to get his other eye done...
