I think you should follow your doctors advice. Also look into the Gas Permeable lenses as a cure there are quite a few studies going on now about this phenomena.
Did you look at the links I gave you before? Secrets are hard to keep in the age of the Internet and there are some great sights that give the ‘Method secrets’, with updates, away for free.
Your question came through in the genealogy forum and there is an Optical forum here on Y!A where physicians hang out and Sarek of Vulcan is not one of them, I hope anyways.
