Hello,I had lasik 2.5 months ago. After 2 weeks I noticed a tiny horizontal smudge in the center of my vision in both eyes, almost like light is refracting differently off of a tiny line in the center of each eye.2 months ago, when this started, I went to an optometrist nearby and she said everything she could see looked good but wanted to send me to a retina specialist since it was a problem with my central vision. It’s not blurry though, like a tiny horizontal smudge on a pair of glasses, in both eyes that hasn’t changed at all since it started March 19.After the optometrist I went to see the surgeon who did my lasik procedure and he didn’t see any problems, maybe a little wrinkle in the left eye but it wouldn’t be something I could see. He said to follow up in a week at the clinic.I went to the follow up with an optometrist at the surgery clinic, didn’t see any problems. Said maybe it’s from dry eye and to use only preservative free eye drops every 1-2 hours for 2 months (the week before I asked the surgeon if I should be using only preservative free eye drops and he said it didn’t matter). Now I’m 6 weeks with heavy use of preservative free drops, no change at all. A couple of days I’ve been out hiking and didn’t use the drops for hours, when I got back to the car I checked for the smudge by closing one eye at a time and it was no worse at all. I can wasn’t dying for the drops either, my eyes didn’t feel dry or irritated at all.Yesterday I went to the retina specialist & was told that my retinas are “very healthy.” He said the smudge could be due to dry eye and he will send a note back to the optometrist to treat me for dry eye. I have seen blurry vision as a symptom of dry eye, but my vision isn’t blurry. And my symptom doesn’t change at all depending on frequency of use drops, screen time, nothing. Not that I can tell at least, same little smudge always there.1. Could my symptom really be caused by dry eye? Even if for 6 weeks there has been no improvement with LOTS of drops?2. What else may cause it?3. I have the 2 month follow up with the surgery clinic in 1 week (2 months from frequent drop use, 3 months post-op). What should I be asking them? I feel like they are going to keep telling me it’s dry eyes and to do the same thing which has had no effect...4. Also the ophthalmologist today mentioned that my cornea is very pitted. I should have asked what that means - Is that a common term? What does it mean? What would treatment be?Thank you so much!
