I have had eye surgery twice ( removal of Terigima) not sure if I spelled that right-I had growth of yellow on the eye and when it reached the color of my eye they wanted to remove it. The first surgery was 19 years ago and the most resent was 6 years ago. I noticed that after the last surgery my eye didn't feel the same. On and off I had a onset of red burning and stinging sensation. Now it just seems to be constant everyday. I have tried all kinds of drops and nothing seems to work. Even drops with no preservatives, Now that it is constant I am kinda worried- I am asking here and not at the doctors because I have been laid off and I no longer have insurance. Just wondering if I should be concerned.
