What is your thought to the reason I have had headaches every day ever since surgery? I never have had such ongoing headaches before, so this is definately related to the eye surgery. i was told that due to the fact that i have an astigmatism of .75 left in my left eye that it is causing headches. I had a pair of glases made to correct the astigmatism but that did not solve the problem of the dull headaches.However I did notice a marked difference in the acuity of my vision in that one eye with glasses. Would a topography test be able to show anything that is wrong such as excessive edema behind the eye or what ever the cause of these headaches are from? I don't know why my dictor ahs nto even suggested the test knowing that this is not normal. i do want to mention that I have had problems with dry eyes but since ahve had plugs put in and they seem to be much better, but could severe dry eye really cause headaches every day?
