Cataract right eye
I had a cataract operation in October 2017 and all has been well until about 3 days ago since then I have been seeing a circle with black edging continually in the same eye.
I went to the opticians but they said to go to the emergency eye hospital.
Thanks for your Question
You should visit the emergency room as soon as possible because you might have retinal detachment or vitreous hemorrhage which manifestate as sudden eye floaters.
