Catarats Surgery

I am a part-time writer and college professor. That is why I do not have medical insurance. I have developed catarats in one eye, and the other eye is starting to get it. Operation for both eyes is $5000  or $2600 per eye. If I can't get operated soon, i will lose my eyes forever and will not be able to continue my careers.
I can send anyone who donates $50 or more a signed copy of my latest book, Globalizing the Curriculum with the Latino Literature of the U. S. You can use it in your classroom or give away to your favorite teacher. Any help is greatly appreciated. Thank you
