I'm 4 months post vitrectomy in my right eye. After about a month I noticed a distortion in that eye at the center of my FOV as when reading a line of text, there is a slight dip down that looks like a sloppy print job. Just had the full monty of tests this week in prep for a cataract insertion soon. I asked about this and my surgeon showed me that the back lining (?) of the repaired eye was thicker than the unrepaired eye causing distortion. This may be from swelling and reduce some, or it just may be the way that things are to be for me. It's slightly annoying but certainly livable. I hope you get helpful answers and treatment - best of luck!
