Hi, I have operated with lasik surgery 2 years ago. and my vision is normal sometimes. I feel blurry vision and when I was operated doctor said when you feel headache and blurry in future there is only one choice of treatment that is your refresh tear eye drop. and I have minor swelling under my eyes it's present. since when I was not operated, is there any other reason behind swelling my power was sph-5 and cyl-2.5 and it was examined just one day before surgery and there was no suggestion to me about stable my power but I never feel any abnormality but only blurred vision sometime and also know about swelling.
