About eighteen months after I had lasik my left eye (previously -8.50) began regressing rather rapidly form -1.- with about .50 astigmatism to -3.25 with 2 astigmatism within a few months. My right eye has regresses slightly but not significantly. Has anyone experienced anything like this? I am particularly surprised as it happened so long after treatment. I am at the moment looking into the possibility of successful re-treatment.
