Seeing Shadow, Double or transparent reflection at the bottom of every object 7 months post LASIK, advice?

I had lasik surgery in May 2017. From last few months I have observed double vision(shadow) of any thing on contrast and their appears a shadow of what I see at the bottom of it. If there are two line written on white paper, I will start seeing the top line overlapping on the bottom line, thus making it difficult to read and concentrate. This doesn't happen always. Mostly while watching TV, looking at phone screen, etc. Any suggestion, advice will be highly appreciated.
