White dot on eye

After having cataract surgery done a few weeks ago  ( had both eyes done over a course of two months )I have noticed a tiny white dot  like size of a needle on one of my eyes and it actually kind of moves or jerks a tiny bit . Has any one noticed or had this ? Like I said I have only noticed it in one eye . Any one ?

Is it in your vision or do you see it in the mirror. 

I see it in the mirror .. it is a tiny speck 

I too have seen this immediately after my cataract surgeries. Some people call it a 'white piece of lint' in my eye. Nor sure what it can be but if light is shinning behind me and I am looking in a mirror I also get a reflection of my lens in my right eye
