I have done Prk eye surgery before 2 months. My left eye vision is perfect but right is not perfect. Although my near vision is also affected in right eye. I feel slight irritation and sometimes itching in right eye when I am using mobile and computer. Too much difficult to focus from both eyes. After closing left eye when I am focusing too much from right eye then for only some seconds it looks too clear and after that it became blurr again. How much time it takes to settle this effect?
