You need to see an eye MD ophthalmologist perhaps the one that did the laser treatment. Need to rule out retinal detachment or tears.

Hi, I am a community leader here not a doctor. I have a lot of experience helping eye patients including myself. Welcome to our community.
I assume you can see the line in your vision. I would get re-checked by an eye MD as soon as possible. These could be floaters, or a sign of a problem. Find an eye MD, an ophthalmologist, at www,aao,org, if you do not already have one.
Dr. hagan will review my response to you and add helpful information.
Write back when you need to.
